1. INTRODUCTION

OVERVIEWThe Model 1516 SentriVoice and Model 1517 SentriVoice+ are alarm monitoring andreporting systems that alert a radio receiver or a pager with voice or text messages whenalarm conditions are detected.

The standard SentriVoice consists of a single circuit board (PCB) which comes in a sheetmetal clamshell enclosure (measuring 10.6 x 7.4 x 2.6 inches). It is compatible with mostradios and can send an alert if a monitored input becomes active.

The standard SentriVoice+ is housed in a fiberglass/polyester NEMA 4Xi enclosure. TheSentriVoice+ uses the same circuit board as the SentriVoice; however, it also includes 40seconds of voice storage, Motorola and GE 2 tone paging capability, a seven amp-hourrechargeable lead-acid battery, and mounting hardware. Like the SentriVoice, theSentriVoice+ is compatible with most radios. The mounting hardware includes the sheetmetal needed to mount the PCB and user selected radio in the enclosure.

The SentriVoice+ operates exactly the same as the SentriVoice. The products monitor eightinputs, provide up to 16 messages, and report change of input status via a radio. Input statusis reported as a coded tone followed by a pre-recorded voice message (voice is an option forthe SentriVoice). The coded tone can be DTMF and an alarm tone. The voice message is pre-recorded by the user prior to the unit operation. A status message can be repeated up to ninetimes in one transmission. The user can elect to send up to 14 transmissions, over a fixedduration, or the user can select to repeat the transmissions until acknowledged by the user.The user can select to repeat transmissions every minute or once every 99 minutes. The usermay select to cancel the alarms remotely via a DTMF keypad. In addition, the user may havean “ALL CLEAR” message sent out, when no alarms are present, up to eight times a day.

The SentriVoice and SentriVoice+ monitor eight discrete inputs (contact closures or discretevoltage levels). The user can select input debounce times between zero and five seconds.Inputs can be programmed to react to either continuous or momentary relay closures.Selecting continuous requires that the input signal remain at a level before a status messagewill be sent. If the signal level changes, a “Clear” message can be programmed to be sent.Selecting momentary causes a message to be sent even if the signal level changes during thealarm cycle.

Up to 15 SentriVoice or SentriVoice+ units can be interfaced to the same radio. The unitswork with either trunking or conventional radio. The radios that can be accommodated in theNEMA enclosure include 2W, 15W and 25W units (29.7 - 50MHz, 136-174MHz, 450-512MHz, and 806-870MHz). The user can select the pre-key time from 0 to 5 seconds.

i National Electrical Manufacturers Association enclosure that is rated to protect against wind, dust, water spray,corrosion, or formation of ice on the enclosure.

Introduction

3. INSTALLATION

INSTALLATION WARNINGThis equipment generates, uses, and can radiate radio frequency energy, and if not installedand used in accordance with the instruction manual, may cause interference to radiocommunications.

Installation of the SentriVoice or SentriVoice+ alarm system should be accomplished byqualified radio service personnel.

WARNINGShipping the lead acid battery back to the factory inside the NEMA enclosure willcause damage to the enclosure, and/or the battery. Zetron will charge the sender forany damage incurred as a result.

HARDWARE INSTALLATION OF THE SENTRIVOICEThe SentriVoice is usually co-located with the radio transmitter. The SentriVoice can bewall-mounted in any position. The preferred orientation is with the wiring entering from thebottom to prevent foreign objects from dropping into the cable opening.

The connections to the radio are PTT, COR, audio in, and audio out found on P2. Inside theunit, there is a telephone jack for programming functions and recording voice messages via aDTMF telephone.

CAUTIONThe telephone should not be left plugged in while the unit is hooked to the radiochannel.

Wire each switch/relay contact to the appropriate alarm input according to Table 3-1. Makesure that you wire each switch/relay common to either pin 3 or 4 of P2.

Note: The COR input is pulled high through an internal 10-kΩ resistor. If you programthe COR level to active high, you may need to connect JP3, grounding the CORinput to allow programming. JP3 pulls the COR input to ground.

See Figure 3-1 and Figure 3-2 for enclosure details.

HARDWARE INSTALLATION OF THE SENTRIVOICE+Figure 3-3 shows a 3-dimensional representation of the SentriVoice+. There are three piecesof sheet metal: 1) the panel, 2) the PCB mounting bracket and 3) the battery bracket. Thepanel basically provides the connections between the enclosure and the rest of the internalcomponents. The PCB mounting bracket holds the Model 1517 PCB to the panel. The batterybracket helps hold the battery in place. The four-inch by six-inch area beside the batterybracket is available for mounting miscellaneous I/O isolation devices. For the purposes ofthis discussion, the side of the enclosure with the hinge attached will be called the left sideand the side of the enclosure with the no hinge will be called the right side.

It is recommended that the mechanical and electrical components be assembled outside of theenclosure. Since the electronics are “static” sensitive, it is recommended that a “static” safearea be used. The battery and charger are generally shipped in a separate package. Theseitems should be removed from their package now.

To remove the internal components from the enclosure, remove the four corner screws on thepanel. Carefully lift out the panel with components attached. Remove the four corner screwsof the PCB mounting bracket and set aside.

At this point, necessary holes should be drilled into the enclosure. To maintain the NEMA4rating, all holes need to be sealed so that water cannot leak into the enclosure. Usually, agood quality RTV glue works well in this application. All work on the enclosure should bedone prior to replacing the panel components. The battery charger can be mounted eitherinside or outside the enclosure. The chargers have three-prong plugs designed for pluggingdirectly into a 120V AC wall socket.

The radio should be the first device mounted on the panel. The maximum dimensions for theradio - including cable strain relief - are 7.75" wide by 3.75" high by 10.75" deep. Holepatterns are provided for a Motorola RNet 150 or 450 telemetry radio, a Motorola RadiusGM300, a Metricom Utilnet Series II, or a Standard Communications CU33U RF DataTransceiver (voltage adapter required). Use the radio’s installation hardware to mount theradio to the base panel (see Figure 3-4).

To install radio power, two spade lugs are provided. Spade lugs for AC power are providedalso. Make sure the larger of the two types of spade lugs provided are used for radio power.Radio power can be obtained from the charger card mounted on the battery bracket.

Table 3-3. Radio Power Connections

Radio Power Lead ChargerV+ V+ OUTGND GND

It is recommended that the radios be mounted so that the controls are accessible through theright side, underneath the PCB mounting bracket. In addition, the antennae and power cablesshould be routed back toward the left side of the enclosure. The control cable for the Radiusradios should be routed out through the right side but away from the radio controls. SeeFigure 3-4. Figure 3-5 shows the generic radio cable shipped with each SentriVoice+. Thiscable should be attached to the radio before the mounting bracket is installed.

Once the radio is installed, the PCB mounting bracket should be reinstalled on the panel.Screw the four corner screws firmly in place. Care should be taken to ensure that the bracketclears the radio. The control/power cable should be connected between the PCB and theradio. The power cable will be attached to the battery later. Those models of Radius radiosequipped with the “Expanded Accessory Connector” allow power from the connector to beswitched to the PCB through the radio’s power switch.

Once the cabling is attached (see Figure 3-3 for power cable routing), the panel should bereinstalled in the enclosure. Screw the four corner screws firmly in place. The upper leftscrew is difficult to reach. A piece of “double-back” tape may help hold the screw to thescrewdriver until the threads of the screw can mate with the socket.

The battery should next be installed on the panel. The battery terminals should be placed sothat they are accessible. The battery bracket should be screwed in place to hold the battery.The battery cable should be connected between the battery and the radio. If power for thePCB will not be switched through the radio, then an additional set of battery wires needs tobe connected to P1 of the PCB. If the battery is charged, and the power connection to thePCB is active, the power LED of the PCB should light. If it will be some time before thecharger is attached, disconnect the positive terminal lead(s) to the battery to preventunnecessary battery discharge.

1. GROUND CONNECTION: Connect a chassis ground wire from P2 pin 14 to thechassis ground of the radio transmitter/receiver. We strongly recommend -- especiallywhen using low-level, non-preamplified microphone circuitry -- using shieldedcabling for audio connections between the controller, microphone, and the radio. Inaddition, one primary point should be chosen as system ground to reduce ground-loopnoise.

2. POWER SUPPLY: The SentriVoice can be supplied with a 9 VAC wall transformer.Connect the leads to pins 1 and 2 of P2. If a 10.5 to 16 VDC source is available, it may

be used instead (through pin 1 for “+” and pin 3 for “-” [or common]). Power input isprotected with a 1 A fuse. The SentriVoice+ has its own power supply.

3. TRANSMITTER PTT: Several ways of keying the transmitter are possible dependingon the requirements of the transmitter. The PTT relay can be programmed to benormally open or normally closed with JP8.

4. COR INPUT: Connect P2 pin 10 to the carrier-operated relay output from thetransmitter. See the Software Installation subsection to program COR active low oractive high. COR is set at 2 V at the factory but may be adjusted from 0.1 to 4.5 Vusing R61.

5. AUDIO OUTPUT: Connect P2 pin 11 to the microphone audio and pin 12 to its braidor ground. Adjust R36 and jumper JP5 for signal level from 20 mV to 2 V pp.

6. AUDIO INPUT: Connect P2 pin 15 (pin 14, shield) to the receiver audio out,headphone jack, or speaker. Adjust the audio level at the receiver to 1-2 V p-p. Checkthe audio level at TP4. If the signal is too high, install JP4 and adjust R62. DTMFtransmitted over radio channel should not be clipped at this test point.

7. If you are connecting more than one SentriVoice or SentriVoice+ to a single radio,connect the transmit request line of each SentriVoice or SentriVoice+ to each other.This line prevents more than one SentriVoice or SentriVoice+ from transmitting atany time. The SentriVoice or SentriVoice+ units should all be programmed by theinstaller to have different unit IDs. The SentriVoice or SentriVoice+ with the lowestunit ID will have priority in transmitting alarms. The transmit request line regulatesthe use of a single radio transmitter by up to 15 SentriVoice or SentriVoice+ units.

INITIALIZATION MODEThere are certain parameters that must be configured when the unit is first placed in service.These are accessed via a special programming mode called the initialization mode. Thismode is described in Section 5 of this manual. The parameters set from this mode are:

• Unit ID number

• Command preamble

• Security code

• Reset programmable parameters to factory defaults

• Configure Radio parameters

4. BASIC OPERATION

OVERVIEWSentriVoice or SentriVoice+ has three modes of operation:

1. Initialization mode2. Programming mode3. Operational mode

To give the user feedback during the three modes, SentriVoice or SentriVoice+ has fourdifferent audio tone combinations:

1. A progress tone for a successful DTMF entry2. An error tone for a faulty input or undefined command3. An alert tone that precedes a voice message4. An exit tone signaling that you are exiting from programming mode

INITIALIZATION MODEThis mode is used to initialize the unit with a DTMF telephone or radio. It allows the user toconfigure it for use in a multi-unit system, specify the communication protocol to use toprevent false signals from triggering a response, and define a security code to preventunauthorized access to the programming functions. The initialization mode is entered bygrounding TP2 momentarily after power is turned on. See the topic “Firmware InitializationMode” in Section 5 for more information on the initialization mode.

PROGRAMMING MODEThis mode allows the user to modify the system’s working parameters, such as the alarmtype, interval, count, and voice message. The programming mode is entered at any time bykeying the correct security code from any DTMF radio or local telephone or by using a PC orterminal.

Although the programming mode is conveniently reached at any time, after installation thereis little need to do so. The SentriVoice or SentriVoice+ is designed for unattended operationuntil an alarm is detected, and then interaction is not required but it is allowed for userconvenience. See Section 5 for more information on the programming mode.

OPERATION MODEThis is the mode in which SentriVoice or SentriVoice+ spends most of its time. Eightdiscrete inputs are monitored for new alarms, alarm cycle timing is running, and the radiochannel is monitored for operational commands. These operational commands allow the userto control the remote control relays, interrogate the status of the alarms, acknowledge alarms,start an alarm cycle, arm/disarm alarms, or enter the programming mode.

Basic Operation

4-2 025-9302

SentriVoice or SentriVoice+ Command ProtocolSentriVoice or SentriVoice+ continuously monitors DTMF activity on the radio channel forcommands. However, it ignores all sequences unless they match the structure shown below.

Preamble (user defined, by default 10) Pound key Unit ID (addressee -- 1 or 2 digits, default 1) Command/Parameters (default security code = 987

pp # u ccc

Figure 4-1. DTMF Command Structure

This command structure prevents random (or purposeful) DTMF activity on the channel fromcausing false commands to be executed. If this sequence is found to match other activity onthe channel, the preamble can be changed to a sequence less likely to cause falsing (seeSection 5 for RS-232 and DTMF programming).

The Model 1516 times out after 5 seconds of inactivity when decoding the preamble-#-unit-ID digits. Once a valid preamble-#-unit-ID sequence has been decoded, the Model 1516times out after 30 seconds of inactivity while decoding the command.

The Model 1516’s responses to DTMF commands are given in Table 4-1.

Basic Operation

025-9302 4-3

CAUTIONUse caution when the Model 1516 is installed on a full-duplex radio. The executionof operational commands takes precedence over alarm transmissions. Issuing acommand to the Model 1516 while it is transmitting an alarm will stop that alarmfrom going out over the radio. The alarm will not be repeated until after the intervaltime, if the alarm remains active.

Operational CommandsListed below are the day-to-day operational functions that can be accessed and the DTMFcommands required to perform these functions. Each command must be preceded by thepreamble/#/unit ID sequence.

010 Deactivate control relay 1.

011 Activate control relay 1.

020 Deactivate control relay 2.

021 Activate control relay 2.

03n Play status of alarm n (1 to 8).For a status alarm type, the corresponding voice message will be played for contact openor closed. For any other alarm type, if the alarm is not active, a “di-di-di” tone will beheard; if the alarm is active, the voice message assigned to it will be played.

04n Acknowledge alarm n (1 to 8).This will stop the alarm cycle until the alarm is reset (a closed contact is opened or vice-versa).

05n Start an alarm cycle for alarm n (1 to 8).This starts an alarm cycle remotely by command rather than and instead of a contactclosure. The complete alarm cycle will be heard for the full alarm count unless it isacknowledged.

06n Disarm alarm n (1 to 8).The contact activity will be ignored and no further alarms will be heard from this alarmuntil it is rearmed. The active alarm must first be acknowledged before it can be disarmed.

07n Arm alarm n (1 to 8). Re-enables the contact from the disarmed state.

xyz Security code. Default = 987.Any three-digit command, which does not begin in zero, will be interpreted as a securitycode. If it matches the programmed code, the programming mode is entered. If it does notmatch, a busy tone will be heard when the channel becomes available.

Basic Operation

4-4 025-9302

Wild CardA “wild card” effect is possible by using zero (0) for n in the operational commands 03nthrough 07n. By using the wild card, all eight inputs can be addressed with one command.

For example, “040” would acknowledge all eight alarms (whether they are active or not) withone command.

BATTERY OPERATION (SentriVoice+)The standard battery supplied is a 7 amp-hr, lead acid gel cell. A fully charged battery canprovide 350mA (5% of the battery capacity) continuously for 20 hours. As the current draingoes up, the amp-hr capacity is reduced in a non-linear fashion. As an example, for acontinuous draw of 700mA (0.1 battery capacity) battery life is only about 9 hours. At 7.5amps, battery life is about 20 minutes. The end of the battery life is considered the pointwhere the battery voltage drops below 10.5V.

A practical example of battery life should be useful. A 2-5 watt telemetry radio drawsbetween 900-1500 mA during transmissions. Assume that the transmissions last about 15seconds (including one second for keyup/down time) and transmissions are sent out 10 timesa day. Total current draw is (90 seconds/3600 seconds/hr) x 1.5A = 0.038 amp-hr. The radioshave a standby/receiver current of only about 50 mA. The SentriVoice or SentriVoice+ drawsabout 105 mA typical. Thus the daily (24-hour) continuous current draw is 24 hours x 0.155A= 3.72 amp-hrs. The 7-amp-hr battery would be expected to last about 44 hours if powerfails.

For a 25-watt radio, typical standby current could be 395 mA. In addition, the current drawduring transmissions can be 7.5 amps. Again, the SentriVoice or SentriVoice+ draws about105 mA continuously. The daily continuous current would be 24 x 0.5 amp-hr = 12 amp-hr.Each transmission (assuming 15 seconds) would require (15/3600) hr x 7.5 = 0.031 amp-hr.However, the heavy current drain triples the affect on reducing the battery capacity.Nevertheless, even with 10 transmissions per day, the current drain from the battery is verysmall (under 0.5 amp-hr per day) compared to the typical current drain (0.5 amp-hr/hr). Thebattery would last about 10-12 hours.

The above examples assumed that the temperature was about 20 degrees C. For low drainapplications (i.e., 300-700 mA) every 10 degrees C drop in temperature below 20 degrees C,the battery capacity drops about 10%. If the temperature is at -20 degrees C, the batterycapacity is reduced to about 60%. For a high drain application (7.5 amps), the capacity isreduced to 20% at -20 degrees C.

Before closing this topic, here are a few final notes about lead-acid batteries. If the battery isdeep discharged too many times, the battery capacity will be reduced. Batteries should not bestored more than 9 months without recharging them. Temperatures above 50 degrees Creduce battery life. For more information on the affects of storage, current drain, andtemperature on the battery capacity, see Yuasa’s application manual for the NP series ofmaintenance-free rechargeable batteries or contact your battery dealer.

CHARGER OPERATION (SentriVoice+)The standard battery charger for the SentriVoice+ outputs 13.7 VDC during idle/standbyoperation and can supply up to 2 amps for charging a depleted battery. About 105-280 mA isrequired to operate the SentriVoice+ PCB. The radio is assumed to draw between 100 mA to400 mA in standby mode. When the radio transmits, it may draw 6 amps or more. Thebattery will supply the additional needed current. The charger is protected against shorts. Thecharger will typically charge a totally dead 7 amp-hr battery in about 4 hours.

5. PROGRAMMING

SentriVoice or SentriVoice+ is preprogrammed at the factory. For most applications, the onlyparameters the user needs to enter are the voice messages and DTMF strings. Before youstart programming the SentriVoice or SentriVoice+, we strongly urge you to fill out theprogramming worksheet in Section 10. Always check the default settings to see if they needto be changed for your application. Please avoid changing the defaults if you do not reallyneed to - historically this is when most programming errors occur.

There are two ways to program the SentriVoice or SentriVoice+:

1. From a DTMF telephone or radio (see next subsection)

2. From a terminal or PC running a terminal emulation program via the RS-232 port (seeRS-232 Programming subsection)

For DTMF programming, most of the parameters are modified in the programming mode,but some parameters, such as unit ID, are modified in initialization mode. The initializationmode is only accessible via the local telephone port, thus requiring the operator to bephysically present at the unit. The general DTMF programming mode can be accessed via theradio as well.

For RS-232 programming, all parameters may be modified in programming mode. Someparameters require that the unit be turned off and then restarted to become effective. It is agood practice to restart the unit after a programming session. Be aware that doing this candump alarm status information, so some caution must be exercised as to when you do this.

PAGING OPTIONSThere are additional programming commands that are used to enter the pager capcodes whenone of the paging options is installed in the unit. A detailed explanation of these commands isfound in Section 8 of this manual.

DTMF PROGRAMMINGThe following operating parameters of the SentriVoice or SentriVoice+ system are fieldprogrammable by the system operator via DTMF commands:

Initialization Mode: — only accessible via local telephone port

• Specify Unit ID

• Specify Command Preamble

• Specify Security Code

• Reset Factory Defaults

• Configure Radio Parameters

Programming

5-2 025-9302

For each monitored input:• Set voice message length and record and playback message

• Enable/disable voice message

• Set alarm type (NO, NC, momentary, status, NO with clear, NC with clear)

• Enable/disable DTMF string

• Enable/disable DTMF unit ID/alarm #

• Program 1- to 15-digit DTMF string

• Set debounce

For each control relay:• Set momentary output

Global/system parameters:

• Set number of alerts per alarm cycle

• Set interval between alerts

• Enable/disable siren

• Set all’s well message interval/disable

The factory provided default parameters are designed to fit most applications and simplifyinstallation. The user may elect to use these values unchanged, requiring little programmingin the field.

Note: The COR input is pulled high through an internal 10-kΩ resistor. If you programthe COR level to active high, you may need to connect JP3, grounding the CORinput to allow programming. JP3 pulls the COR input to ground.

Programming considerations specific to DTMF programming are discussed further in“Programming Mode” starting on page 5-5.

Firmware Initialization ModeIf you are programming the SentriVoice or SentriVoice+ with a terminal or PC, thissubsection does not apply.

Note: SentriVoice or SentriVoice+ is shipped with default settings that will eliminate theneed for many users to ever use the initialization mode. Check these parameterscarefully. If you do not need to change them, DO NOT enter initialization mode.

If you are installing more than one unit, want to change the command preamble, or want tochange the security code, you will have to enter the initialization mode.

Programming

025-9302 5-3

Entering Initialization Mode1. Remove the cover of the SentriVoice or SentriVoice+.

2. Plug in the local programming telephone or make sure your transmitter isconnected correctly and powered up.

3. Apply power to the unit and touch and release a ground wire to TP2 near U12 (thesquare microprocessor). The unit issues a six-beep prompt tone to the localtelephone to indicate it has entered the Initialization mode.

You are now in the initialization mode and the only valid commands are found in thissubsection and summarized in Section 9.

Note that the initialization mode programming commands are not preceded by a preamble asin the operational mode and are therefore subject to falsing by channel traffic. Run theinitialization mode with the local telephone or when the channel is quiet or has a minimum ofDTMF activity.

Initialization Mode Programming Commands

0xx Program the prekey time. Default = 05.Set the time xx in tenths of seconds (00 to 50) that the SentriVoice or SentriVoice+ mustwait after pressing PTT and before transmitting the page.

10d Program the number of digits in the unit ID. Default = 1.Enter the number of digits "d" (1 or 2) in the unit ID. A unit is addressed by specifying thecorrect unit ID in the command structure in operational mode. A single digit ID isadequate to specify one to nine different units. However, by specifying two digits, the unitID can range from 01 to 99. (units 1 through 9 must have a leading zero in a 2-digitsystem.) If more that one SentriVoice or SentriVoice+ is being installed, their unit IDsmust all be set to the same length.

Note: An ID of “1” is not the same as an ID of “01”.

2uu Program unit ID. Default = 1. Enter the unit ID uu (0 to 9, or 01 to 99).

3pp Program the command preamble. Default = 10.Enter the command preamble pp (any two DTMF digits). All future operationalcommands will use these two characters as an enabling preamble.

4sss Program the security code. Default = 987.Enter the security code sss (any three DTMF digits, except that 0 [zero] is not allowed asthe first digit). The security code can be reprogrammed at any time (by entering theinitialization mode) if it is forgotten or revealed.

500 Reset the factory defaults.This command will set all parameters back to the factory defaults. (See CAUTION, nextpage.)

Programming

5-4 025-9302

CAUTIONThe “500” command also resets all message lengths and alarm timings that havebeen programmed into the unit, so use this command only as a last resort. If it isused, you will have to re-enter the time allocations for each voice message yourecorded. You will not have to rerecord the voice messages (See Voice MessageLength on page 5-24).

600 Program COR active low. This is the factory-set default.Selects the voltage state that the transmitter furnishes as a channel busy indication. TheCOR input voltage must drop below the threshold level if active low signal level ischosen. JP3 must be removed to allow proper radio controlled COR operation.

601 Program COR active high.

700 Program for trunking radio operation.Selects trunking operation of the SentriVoice or SentriVoice+. This requires that someform of channel acquired signal logic high or low be connected to the COR input. (Seecommand 600, 601 above).

For trunking operation timing, PTT is pressed for 5 seconds while looking for a channel.If a channel is acquired prior to the end of the 5 seconds (this is based on the logicindication on the COR input), the Model 1516/1517 will wait the prekey delay, send thedata, and release PTT. If, after 5 seconds, there is still no channel available, the Model1516/1517 will release PTT, wait 5 seconds, and retry.

701 Program for conventional radio operation. This is the factory set default.Selects standard operation of the SentriVoice or SentriVoice+. Works on any non-trunking voice transmitter. Channel has to be available before PTT is engaged (this isbased on the logic indication on the COR input) for conventional radio operation.

80x The commands “800” through “805” are used to set global parameters related tothe POCSAG paging option. These commands are described in Section 8.

9y Program voice repeats. Default = 3.Set the number of times y (1 to 9) that the voice message is to be played during a singlealert transmission.

Exiting Initialization ModeThe Initialization mode can be exited in two ways:

1. Pressing the DTMF # or character key. (If your keypad supports fourth-columnDTMF characters, the A, B, C, or D keys will work too.)

2. Cycle power to the SentriVoice or SentriVoice+ off and then on again.

All the programming will be stored even if power is removed.

Programming

025-9302 5-5

Programming ModeEntering the Programming ModeTo ensure problem-free DTMF programming using a telephone, please check the followingitems:

1. Make sure the COR signal is pulled to the correct level (factory default is +5 V).

2. A radio must not be connected to J3.

3. A voice option must be purchased in order to have record and playback voicecapability.

4. Start a new message with the * key. This key clears any spurious DTMF signals fromthe buffer.

If you have difficulty with DTMF programming using a telephone or radio, try resetting thesystem to the factory defaults by using the “reset to factory defaults” command in the RS-232program.

Note: When programming the unit using a DTMF telephone, disconnect the audio fromthe radio (if connected).

To program the unit from a DTMF telephone, power up the unit and plug the telephone intothe modular jack located near the lithium battery. While listening at the handset, press the #key. You should hear a DTMF tone for as long as you press the key. If you do not hear atone, verify that the SentriVoice or SentriVoice+ is on and that the telephone is connectedproperly, or try a different telephone. The DTMF IN LED should be lit while any key ispressed on the telephone keypad.

From the DTMF telephone or from a radio with a DTMF keypad, key in the preamble/#/unitID and then the three-digit security code. As shipped from the factory, the default code is“10#1987”. It can be changed using DTMF commands from the initialization mode (see“Firmware Initialization Mode” on page 5-2). It may also be changed from RS-232programming.

Prompt TonesAt the successful completion of a programming command, three short beeps will be heard. Ifan invalid command is input, an error buzz (low tone) will be heard. If at any time an error isencountered, any further input will be ignored until SentriVoice or SentriVoice+ has a chanceto report the error (with a buzz).

For example, several commands could be given to SentriVoice or SentriVoice+ without theuser unkeying his/her radio. This will work if the commands execute correctly. If an error isencountered in the command string, all commands after the error will be ignored until theunit can report the error (i.e., until the channel is unkeyed so a buzz can be transmitted).

If no programming input is received for 30 seconds, the unit will play an “Exit” prompt (ahigh-low-low tone sequence) and return to the operational mode.

Programming

5-6 025-9302

Before you start programming the SentriVoice or SentriVoice+, we strongly urge you to fillout the programming worksheet found in Section 10. Not only will this help you inprogramming the SentriVoice or SentriVoice+, but it will also provide a record of theparameters you have chosen.

Programming ExampleIn the following example, input #1 has a normally open alarm type and needs to beprogrammed with a 5-second voice message.

Enter Meaning Response10#1987 Access code for programming 3 beeps110 Input 1, full message 3 beeps399 Set message length to 99 seconds (this is an

invalid command)Buzz

305 Set message length to 5 seconds 3 beeps720 Record message (speak a 5-second message

into the phone handset at this time)5-second pause

730 Play the message (the message you justrecorded can be heard in the phone)

5-second message,3 beeps

# Exit programming High beep, 2 low beeps

In this example, you have just programmed input #1 with a five-second voice message to beplayed upon sensing a contact closure. You can follow the example to program the otherinputs. You need not exit programming after each input, simply use the command to specifythe next alarm/message number; in the example above, that would be 120 which specifiesinput #2 (set as an alarm type 1 or 2), full message.

Clearing Partial Input StringPress the * key to clear a partial string from the input buffer.

Exiting Programming ModePress the # (pound) key to exit the programming mode. Any time while in programmingmode, if a DTMF #, *, A, B, C, or D is detected, the unit will leave the programming modeand return to the operational mode. Also, if no input is received for 30 seconds, the unit willplay an “Exit” prompt (a high-low-low tone sequence) and return to the operational mode.

RS-232 PROGRAMMINGThe following operating parameters of the SentriVoice or SentriVoice+ system are fieldprogrammable by the user from a PC (running a terminal emulation program) or terminal viaan RS-232 port:

For each monitored input:

• Set voice message length and record and playback message• Enable/disable voice message

Programming

025-9302 5-7

• Set input (alarm) type (NO, NC, momentary, status, NO with clear, NC with clear)• Arm/disarm alarm• Enable/disable DTMF unit ID/alarm #• Program 1- to 15-digit DTMF string• Set debounce• Enable/Disable optional OUT1/OUT2 if installed, each relay may be latched

momentarily or indefinitely

For each control relay:

• Set momentary output

Global/system parameters:

• Set prekey• Set voice repeats• Set security code, unit ID, and preamble• Set number of alerts per alarm cycle• Set interval between alerts• Enable/disable siren sent with voice• Set all’s well message interval/disable

The factory provided default parameters are designed to fit most applications and simplifyinstallation. The user may elect to use these values unchanged, requiring little programmingin the field.

Note: If no programming input is received for 3 minutes, the unit will issue a timeoutmessage (“Time out. Bye!”) and return to operational mode.

Entering & Exiting the Programming ModeEnteringFollow steps 1 through 7 to start programming from a PC or terminal.

1. With power off, connect your PC or terminal to the SentriVoice or SentriVoice+ 9-pin RS-232 port (J2). There are only three connections required. (Zetron offers twoassembled cables for this purpose. Cable number 709-7144 is for DB-9 to DB-9applications, and cable number 709-9030 is for DB-25 to DB-9.

J2 Pin Function 5 Ground 4 Receive data (SentriVoice or SentriVoice+ input) 3 Transmit data (SentriVoice or SentriVoice+ output)

2. Turn on power to your PC or terminal.

Programming

5-8 025-9302

3. Make sure your PC or terminal is set at 4800 baud, 8 data bits, no parity and one stopbit (4800, 8, N, 1).

4. Turn on power to the SentriVoice or SentriVoice+. You should see a sign-on messageon the terminal screen when power is applied to the SentriVoice or SentriVoice+. Ifyou do not, you have probably either set the wrong baud rate or reversed the receiveand transmit lines.

5. Press the space bar three times.

6. If connections are correct, for the standard firmware you will see the following menu:SentriVoice Main Menu

0) Reset factory defaults1) System setup Menu2) Alarm settings menu3) Input menu4) Output relay menu5) Voice menu6) DTMF output menu7) Paging Menu ∗8) Dump configuration

Select option or ESC:

7. Use your programming worksheet (from Section 10) and the information in thefollowing subsections to program the SentriVoice or SentriVoice+.

ExitingPress the escape key (ESC) as necessary to return to the top menu. Press the escape key onemore time and you will be prompted to confirm that you want exit the programming mode.Answer this prompt as instructed on the terminal screen (by pressing the “Y” key) to exitprogramming. The unit will respond by returning the message “Bye…” and returning tonormal operation.

ErrorsWhile in the RS-232 programming mode, errors will generally cause the terminal or PC toissue an audible “beep” prompt. The message “Illegal Entry!” is sent to the screen, afterwhich the last item or sub-menu is reprinted. Illegal sub-menu commands always return theunit to the Main Menu screen.

Using the MenusThe format of all menus is the same - a title at the top, a numbered list of menu options in themiddle, and a prompt at the bottom (some menus have an additional information linebetween the last menu option and the prompt).

∗ The “Paging Menu” selection only appears if the unit has one of the following paging options installed: Two-Tone, Plectron, or POCSAG. If the Five/Six Tone option is installed, then this menu selection will be “ToneGroups Menu”. If no paging option is installed in the unit, then “Dump Configuration” moves up to become itemseven on the menu.

Programming

025-9302 5-9

Select a menu option by pressing one of the number keys on the terminal. For example,pressing the 0 key would select the reset factory defaults option. You would then be shownthe following prompt:

Are you sure you want the default settings Y/N?

Here, SentriVoice or SentriVoice+ is asking a question that can be answered only by pressingone of the keys shown in curly brackets - in this case, either the Y or N key (for Yes or No).

Most often, this type of prompt is used to ask you about changing one of the settings in aSentriVoice or SentriVoice+. You will often be shown the current setting before being askedto enter a keystroke, as in the example that follows:

Radio selection is now conventional.Select Trunking or Conventional operation?

You may need to change settings that cannot be specified with a single key-press. In thesecases, you are shown the current setting followed by a prompt ending in a colon, as shownbelow:

Security code is now 987.Enter security code :

In this case, you should type in the new setting, then press the Enter or Return key.SentriVoice or SentriVoice+ knows what type of input to expect and only allows you to entervalid characters. In the example above, SentriVoice or SentriVoice+ was expecting DTMFdigits, so would only pay attention to the keys 0-9, # and *.

While entering a value, you can correct a mistake by pressing the backspace key on thekeyboard. This simply erases the most recently entered character.

When SentriVoice or SentriVoice+ is expecting a specific number of characters (three in theexample above), it will ignore the Enter key until you have typed all of the digits.

The Esc key has three functions.

1. When SentriVoice or SentriVoice+ is asking you to select a menu option, pressing theEsc key will move you back to the main menu.

2. If you are at the main menu level, pressing the Esc key will give you a prompt askingif you want to exit from the programming mode.

3. When you are asked to enter a new setting, pressing the Esc key will return you to themenu without changing the current setting.

PROGRAMMING COMMANDSThis topic describes the various programmable parameters of the Model 1516 and 1517 indetail. Remember that the commands for the units fall into three broad categories:Initialization Mode, Programming Mode, and Operational. Section 9 of this manual lists allthree groups of DTMF commands in a Quick Reference format. A detailed description of theOperational commands is found in Section 4. The Initialization and Programming commandsare discussed here. The RS-232 programming mode includes equivalent commands for bothinitialization and general programming commands (discussed here); however, the RS-232

Programming

025-9302 5-13

mode does not have any equivalent for the operational commands. Details on entering paginginformation for the optional formats supported are presented in Section 8.

All’s Well CountMenu Path: Main Menu |Alarm Settings Menu | All’s Well CountDTMF Syntax: 61k where k = number of All’ Well sent in each 24 hoursRange: 0 to 8 timesDefault: 0

The unit is capable of sending an all’s well message to confirm that the unit is stilloperational even though no alarms have occurred. If an all’s well message is used, it isrecorded as the voice message for input #8. If alert messages are required for all eight inputsthen this feature should not be used and the count left at zero.

This feature is enabled by setting the count to some number other than zero. The 24-hourperiod starts as soon as the unit is powered up. The period is divided equally, e.g. 1 = onceevery 24 hours, 2 = once every 12 hours, 3 = once every 8 hours, etc.

All-Call OperationMenu Path: Main Menu | System Setup Menu | All-CallDTMF Syntax: 66x where x = enable (1) or disable (0) the use of all-call IDRange: 1 (enabled) or 0 (disabled)Default: Disabled

When the all-call feature is enabled, it allows the unit to respond to any command addressedto unit ID #99. This provides a system operator the ability to give an operational command toall of the units in the system in one pass. This in no way interferes with a unit’s individualunit ID number. It also cannot replace its unit ID number. Each unit must still be assigned atwo-digit ID during initialization.

Note: Assigning units single-digit ID codes automatically disables the All-Call feature.

Arm/DisarmMenu Path: Main Menu | Input Menu | Arm/DisarmDTMF Syntax: 07n = arm the selected alarm “n”

06n = disarm the selected alarm “n”Range: 1 to 8Default: Armed

This command either arms or disarms the currently selected command in RS-232programming mode. In the DTMF programming mode, the DTMF commands are specific,and the alarm to change is specified in the command string.

CapcodeDetailed information on this command is presented in Section 8 of the manual, “OPTIONS”.

Programming

5-14 025-9302

Conventional/TrunkingMenu Path: Main Menu | System Setup Menu | Conventional/TrunkingDTMF Syntax: 701 = Conventional radio selected

700 = Trunking radio selectedRange: Conventional or TrunkingDefault: Conventional

This command selects the type of radio to which the unit is connected. The default setting isfor a conventional radio. This is programmable with a DTMF command only from theInitialization Mode.

COR PolarityMenu Path: Main Menu | System Setup Menu | COR PolarityDTMF Syntax: 600 = Logic low level indicates active COR signal

601 = Logic high level indicates active COR signalRange: Low or HighDefault: Low

This parameter sets the logic level, low or high, that should prevent the unit fromtransmitting (i.e. indicates an active COR signal from the radio). This is programmable witha DTMF command only from the Initialization Mode.

Note: If the COR Polarity command is used to change the active COR setting for theunit, the operator must also change the position of jumper JP3 to match the newpolarity setting. Failure to change the jumper setting interferes with the normaloperation of the unit.

DTMF StringMenu Path: Main Menu | DTMF Output Menu | DTMF StringDTMF Syntax: 8xx where xx = number of digits in the DTMF stringRange: 00 to 15 digits in length, valid digits 0 to 9, *, #, A, B, C, DDefault: Blank

This command is used to enter a DTMF string up to 15 digits in length. This string is playedpreceding any voice message that is assigned to the currently selected alarm input. Thevariable xx sets the length of the string to be entered. The string that follows the commandmust be exactly the length specified.

Do not use this command to disable the DTMF String feature unless you truly want to set thestring back to blank. To disable the string only temporarily, use the DTMF String On/Offcommand from the DTMF program mode; that is what it is for. Using this command to setthe string length back to zero behaves differently depending on whether it is done via DTMFor RS-232. In DTMF, it hides the previous string, but that string will come back when thestring length is reentered. In RS-232, the string is erased and must be completely reentered.

Note: When this parameter is entered from DTMF programming, it MUST be precededby the “1at” command in order to specify which alarm input it is associated withSee “1at Command for DTMF Programming” on page 5-15.

Programming

025-9302 5-15

DTMF String On/OffMenu Path: N/ADTMF Syntax: 74n where n = the alarm input to enable the DTMF string for

75n where n = the alarm input to disable the DTMF string forRange: 1 to 8 (0 is a global command and sets all inputs to the same state.)Default: Enabled for all alarms.

This command is used to enable or disable the sending of the user definable DTMF string fora given input. Using this command allows the system operator to suspend the sending of theDTMF string without having to erase it from memory. Always use this command when youwant to disable sending the string assigned to an input just temporarily.

MessageThe Message parameter is explained in Section 8, “Options”, at the end of the subsection onthe POCSAG paging format.

Next InputMenu Path: Main Menu | various menus | Next InputDTMF Syntax: 1at where a = alarm input # and t = message typeRange: Inputs 1 to 8, alarm types 0 to 2Default: Input # 1

When programming the unit via RS-232, the specific alarm input being worked on is selectedby means of the “Next Input” command found in the menus dealing with alarm specificparameters (Input, Voice, DTMF Output). Selecting this menu option will increment thecurrently selected input number by one. If the current input is number eight then the selectionwraps around to input one again.

1at Command for DTMF ProgrammingThe “Next Input” command has no direct equivalent in DTMF programming. When workingwith alarm specific commands in the DTMF programming mode, you use the “1at”command to select a specific alarm input. The “a” variable selects the alarm input to work on(enter a number between 1 and 8). The “t” variable selects the type of message to beprogrammed (enter a number between 0 and 2). The message types are:

0 = Full Message1 = First Half of Message (used with Status type alarms when input is open)2 = Second Half of Message (used with Status type alarms when input is closed)

The message types are necessary when this command is used ahead of the commands “720”and “730”. For example, to play back the entire message for alarm input #4 you would enter“140 … 730”. It is important to pause after the initial command so the unit can get out its3-beep prompt; otherwise, it will ignore the second command. Whether an input uses a singlemessage or a two-part message is set by its input type (see “Set Input Type” on page 5-21).

The “1at” command must be used before using any of the following commands: 2xn, 3mm,720, 730, 8xx.

Next OutputMenu Path: Main Menu | Output Relay Menu | Next OutputDTMF Syntax: N/ARange: Toggles between Output 1 and Output 2Default: Output 1

This command is used to toggle the currently selected output between Output 1 and Output 2.There is no equivalent DTMF command to perform this function.

OUT1/OUT2 Alarm ActivationMenu Path: Main Menu | Input Menu | OUT1/OUT2 Alarm ActivationDTMF Syntax: 65nxayb where n = alarm input number, 1 to 8

x = set OUT1 on/off a = latch OUT1 on/off y = set OUT2 on/off b = latch OUT2 on/off

Range: n = 1 to 8, for x, a, y, and b 1 = on, 0 = offDefault: All of the input alarms are set to active both output relays.

If the relay option is installed in a unit, any of the alarm inputs can be configured to activateone/or both of the output relays whenever an alarm occurs. This activation can be set formomentary operation (relay is activated only for the duration of the PTT activation), or therelay can be latched indefinitely, requiring an operator to clear it with a command.

CAUTIONSince the optional relay outputs (K3 and K4) are not monitored, the actual outputstates of the relays cannot be verified from their programming status.

Output DisabledMenu Path: Main Menu | Output Relay Menu | Output DisabledDTMF Syntax: 010 = Disabled OUT1 relay

020 = Disabled OUT2 relayRange: NoneDefault: None

This command is used to disable an output relay that is active. In RS-232 mode, selecting thiscommand disables whichever relay is currently selected. The DTMF commands are specificto individual relays.

PreambleMenu Path: Main Menu | System Setup Menu | PreambleDTMF Syntax: 3pp where pp = the two digits of the preambleRange: 2 digits, valid characters include 0 to 9. *, #, A, B, C, DDefault: 10

This command is used to set a two-digit preamble for the unit. This preamble is sent at thebeginning of operational commands to limit falsing of the unit on DTMF strings that are notactually commands. In DTMF programming, this command is only available from theInitialization Mode.

Prekey TimeMenu Path: Main Menu | System Setup Menu | Prekey TimeDTMF Syntax: 0xx where xx = time delay in tenths of seconds (x 0.1)Range: 00 to 50Default: 05

This command sets the delay interval between the unit keying the radio and transmitting analarm message. In DTMF programming, this command is only available from theInitialization Mode.

Record First HalfMenu Path: Main Menu | Voice Menu | Record First HalfDTMF Syntax: 720Range: NoneDefault: None

This command is used to record the first half of the message (high half) for a status typeinput. For a Normally Close input type with a clear message, this would be the alarm portionof the message. For a Normally Open input type with a clear message, this would be theclear portion of the message. For more information on status type commands, see the “SetInput Type” command on page 5-21.

In DTMF programming this works a little different. One quarter second (0.25) after the “0”key is released (7 - 2 - 0) the unit starts recording whatever is received at its audio input for amaximum time set with Voice Message Length (3mm) and for the specified message type(1at). Both the “1at” and “3mm” must be used before using this command.

Note: The DTMF command “720” is also used to record a full message or the second half of amessage. This command must be preceded by the “1at” command to select an alarminput. The “t” variable selects the message type and thereby the playback mode as well.

Programming

025-9302 5-19

CAUTIONRecord voice messages in numerical order. If you change the length of a message(see “Voice Message Length” on page 5-24), all messages that follow the alteredmessage must be re-recorded. If the alarm type is changed, the voice message forthat alarm must be re-recorded. For details on the alarm type command, see the “SetInput Type” (2xn) description on page 5-21.

Record Full MessageMenu Path: Main Menu | Voice Menu | Record Full MessageDTMF Syntax: 720Range: NoneDefault: None

This command is used to record a single message that uses the full voice message timeassigned to the current alarm input.

In DTMF programming this works a little different. One quarter second (0.25) after the “0”key is released (7 - 2 - 0) the unit starts recording whatever is received at its audio input for amaximum time set with Voice Message Length (3mm) and for the specified message type(1at).

Alarm (Repeat) CountMenu Path: Main Menu | Alarm Settings Menu | Alarm (Repeat) CountDTMF Syntax: 5cc where cc = number of times an alarm is transmitted during

an alarm cycleRange: 00 to 15, 00 = no alarm sent, 15 alarm sent continuouslyDefault: 10

This command sets the number of times an alarm is sent during an alarm cycle. The length ofan alarm cycle is controlled by the number of repeats and the message length. If the value 15is entered, then the alarm is sent continuously until the alarm input either resets or the alarmis manually cleared.

Alarm (Repeat) IntervalMenu Path: Main Menu | Alarm Settings Menu | Repeat IntervalDTMF Syntax: 4ii where ii = the interval between replays of the alarm messageRange: 01 to 99, in minutesDefault: 30

This command sets the length of the interval between repeat transmissions of the alarmmessage when an alarm remains active.

CAUTIONBe sure that the Alarm (Repeat) Interval is set to period longer than the total timerequired to notify all of the programmed alarms. An interval setting that is too shortto accomplish this will result in an inability to acknowledge the alarms. Forexample:

Alarm (Repeat) Interval is set to 1 minuteDTMF + Voice is enabled for all inputs

RESULT: All eight DTMF + Voice alarms require a minimum of 1.5 minutes totransmit. Since the interval timer will have expired long before the alarms finishplaying, the next alarm cycle starts immediately, preventing anyone from havinga chance to acknowledge the alarms.

Reset to Factory DefaultsMenu Path: Main MenuDTMF Syntax: 500 Use this command in the Initialization mode only!Range: NoneDefault: None

If the system parameters are forgotten (or you become so confused that you do not knowwhat is what), this command can be used to reset all parameters back to factory defaults.

Programming

025-9302 5-21

CAUTIONThe reset command also resets all message lengths and alarm timings. While youwill not have to re-record the voice messages, you will have to re-enter the timeallocation for each message you had recorded. Use this command as a last resort!

Security CodeMenu Path: Main Menu | System Setup Menu | Security CodeDTMF Syntax: 4sss where sss = the unit’s security codeRange: 100 to DDD, valid characters are 0 to 9, *, #, A, B, C, D (a leading digit of

Theunit will initiate an alarm cycle based on the condition of an input and the alarm typeassigned to it with this command. This command must be preceded by the “1at” commandsince the unit needs the information contained in its “t” variable. Please see the “1atCommand for DTMF Programming” on page 5-15.

Programming

5-22 025-9302

The available alarm types are:

1 = Normally open (NO), an alarm is triggered at closure2 = Normally closed (NC), an alarm is triggered at opening3 = Momentary NO, an alarm cycle is started at closure4 = Status alarm, i.e. a different voice message is transmitted for closure than for

opening.5 = NO with clear message, similar to type 4; however, the message sent on closure

repeats multiple times while the message sent on opening is only sent once.6 = NC with clear message, similar to type 4; however, the message sent on opening

repeats multiple times, while the message sent on closure is only sent once.

Alarm types 1, 2, 5, and 6 are self-clearing. They will stop right away when the input clears,regardless of the Repeat Interval and Repeat Count parameters.

Alarm types 3 and 4 are not self-clearing. This means, once triggered, they will complete atleast one alarm cycle regardless of the state of the input.

Alarm type 3 requires an acknowledgement from the user. Even if the original alarmcondition clears, the unit must receive the user acknowledgement of the original alarm beforeit can respond to a new alarm condition.

CAUTIONSetting an input to type 1, 2, or 3 while that input is in the alarm state will result inan immediate alarm output.

Set Momentary TimeMenu Path: Main Menu | Output Relay Menu | Set Momentary TimeDTMF Syntax: 62xxx where xxx = the time that relay output 1 will remain latched

63xxx where xxx = the time that relay output 2 will remain latchedRange: 000 to 255 in secondsDefault: 000

This command sets the period that the current relay output will remain closed after it isturned on in the momentary mode. This can be done using the DTMF Operational commands“011” or “021”. Refer to Section 4 for more information on using operational commands.When using the DTMF command, the output affected is specified by the command numberused.

The default setting of 000 results in a latched output that requires the user to send a commandto reset it.

Note: This time period only applies to the behavior of the output relays in response tomanually entered operational commands. It has no affect on their operation inresponse to an alarm.

Unit ID LengthMenu Path: (None — set automatically when the unit ID number is entered)DTMF Syntax: 10d where d = the length of the unit ID stringRange: either 1 or 2Default: 1

This parameter is used only in DTMF programming. It defines the number of digits that aunit ID number must have to be considered valid. This DTMF command may only be used inthe Initialization mode.

CAUTIONLeaving the unit ID length set to its default value, or setting back to a single digit,disables the “All-Call” ID feature. See “All-Call Operation” on page 5-13.

Unit ID #Menu Path: Main Menu | System Setup Menu | Unit ID#DTMF Syntax: 2uu where uu = unit ID#Range: Either 0 to 9, or 00 to 99 (range set by Unit ID Length)Default: 1 (not 01)

This command is used to set the unit’s ID number. When programmed from the RS-232mode, you may directly enter any two-digit number between 01 and 99, or any single-digitnumber between 0 and 9. The Caution regarding the All-Call feature applies to this commandjust as it does to Unit ID Length.

same state)Default: Off

This command is used to enable or disable the sending of the unit’s ID number, alarmnumber, and alarm status whenever an alert is transmitted for a particular input. The formatof the DTMF string is:

uu#as where uu = the unit ID numbera = the alarm input that triggered the alerts = the status of the alarm input (0 = open, 1 = closed)

When enabled, this string follows the user defined DTMF string (if it is in use) and precedesany voice message recorded for the input.

Voice Message LengthMenu Path: Main Menu | Voice Menu | Voice Message LengthDTMF Syntax: 3mm where mm = total time for an alarm’s voice messageRange: 00 to 80 in secondsDefault: 00

This command is used to enter the total time limit for the voice message recorded for analarm input. If the alarm type assigned to the input is the status type (types 4, 5, or 6), theneach half of the message gets one half of the total time set with this command.

When programming via RS-232, this command applies to the current input. Whenprogramming via DTMF, this command must be preceded by the “1at” command to select aninput and set its alarm type.

CAUTIONThe Model 1516 and 1517 units do not sense the total or remaining voice storageRAM capacity. The technician programming the unit must manage the storagecapacity based on knowing what is installed in the unit.

Changing the programmed length (3mm) of any particular message (1at) will resultin all subsequent message lengths (alarms numbers greater than the one justmodified) being cleared to zero. The messages have not been lost, but the memorypointers to their start and stop addresses have been cleared. As long as no newmessages have been recorded, the missing pointers can be restored by re-enteringthe message lengths for all the alarm inputs with numbers higher than the input forwhich the length was changed.

6. THEORY OF OPERATION

INTRODUCTIONThe SentriVoice and SentriVoice+ are a DTMF- and RS-232-programmable eventmonitoring systems with the ability to alert a user, by radio, that a particular input haschanged state. The SentriVoice+ includes a NEMA enclosure, lead-acid battery, charger,tone, voice, or pager messaging on events and radio channel sharing. The SentriVoice orSentriVoice+ can be programmed through a local DTMF telephone interface, a DTMF radiokeypad, and through its microcomputer serial port. Figure 6-1 shows the block diagram of thePCB schematic. Please refer to the parts list, schematic, and silkscreen at the end of thissection for component identification, location, and part numbers.

The SentriVoice or SentriVoice+ systems can be broken into the following functional areas:

1. Embedded microcomputer and support components2. DTMF and tone circuits3. Radio interface circuits4. Reset and miscellaneous circuits5. Optional circuits6. Battery (SentriVoice+)7. Charger (SentriVoice+)

EMBEDDED MICROCOMPUTER AND SUPPORT CIRCUITSThe microcomputer circuit consists of U5, a 68HC11A1 microprocessor, U12, a 27C256EPROM memory device, and a few support components. Code is stored in the EPROM. Themicroprocessor has internal RAM and EEROM (electrically erasable read-only memory).The EEROM is used to store setup parameters. The microprocessor has eight analog 8-bitA/D inputs, which are used as high/low inputs to monitor the events at port P1. The inputsare protected with 10K series resistors. All serial data transfers with a personal computeroccur through the microprocessor’s serial port and U19 (the RS-232 interface component).

The SentriVoice or SentriVoice+ can be programmed through the RS-232 interface, the localtelephone DTMF interface, or the radio DTMF interface. See Section 5 for programmingdetails.

DTMF AND TONE CIRCUITSThe SentriVoice or SentriVoice+ encodes and decodes DTMF signals. In addition, theoptional paging encoder outputs signals for the optional two-tone, 5/6-tone, and POCSAGpagers.

The output tone encoding is accomplished with U6 (DFF), RP1 (R/2R network), andbandpass filters. R36 is used to adjust the output gain for this circuit but since the sameresistor is used to adjust gain for the voice signals, it must be used cautiously. Inmanufacturing, the circuit is adjusted to provide 1 VPP DTMF output at the radio connectorP1.

Decoding of the DTMF signals is accomplished with U9, a DTMF decoding device.Maximum input to the device is 1.4 VPP. In addition, the device is sensitive to high frequencynoises above 28 kHz. To reduce noise to the device, a two-stage input bandpass filter is used.

For the DTMF radio output, the amplifier, U16A, can have a gain of 2 or 20, set usingjumper JP5. R36 is used to reduce the DTMF signal prior to radio output. Note that thisresistor can also be used to adjust the optional voice outputs, as discussed in the OptionalVoice Circuits subsection. The DTMF radio input uses U16B as the buffer with gain of 5.7 or48 selectable by jumper JP4.

Note that the DTMF decoder will work incorrectly if both a radio and telephone areconnected to the circuit board simultaneously.

RADIO INTERFACE CIRCUITSThe radio interface is supported through relays K1 & K2, radio I/O buffers, the adjustablecarrier operated relay (COR) input signal, and the PTT relay. K1 switches both the transmitaudio and the PTT output. The signal used to control K1 also controls the “digital data”control signal, switched through K2, for digital radios. The digital data signal line is used foralphanumeric paging compatible radios. The digital data out signal can be either 0-5 VDC orRS-232 (±7 VDC) signals, selected with jumper JP11.

The COR input signal can be adjusted with R61 between 0.1 and 4.5 VDC. The COR signal isused to determine if the radio channel is clear. Normally, the signal is pulled high but can beprogrammed to be either an active high or low signal.

The PTT relay can be configured to be normally open or normally closed and connected toeither circuit ground or PTT common. JP8 allows the user to select between normally open ornormally closed. JP7 allows the user to select +5 VDC as the open circuit voltage. JP6 allowsthe user to select PTT out as either PTT common or circuit ground.

RESET AND MISCELLANEOUS CIRCUITSThis subsection covers the reset circuit, output power jumper, and LED indicators.

A 6.8 VDC Zener diode, CR1, is used to set the system “reset” level to about 8.0 VDC. Theinput power voltage must be above 10.5 VDC to ensure correct system operation. Q1 and Q2are used to discharge the reset capacitor, C32, quickly and allow the capacitor to charge upslowly (about 3 milliseconds to reach the 1.2 VDC threshold of U11). A manual reset jumper,JP1, allows the user to manually reset the circuit as required.

Jumper J12 can be used to connect the external power input (J2 pin 1) to J3 pin 6. Note thatthe maximum power that can be pulled through this connection is less than 1 A due to thesystem 1 A power fuse used for fire protection.

Two LED indicators are used in the system. One LED, DS1, flashes to indicate that themicroprocessor is servicing an I/O event. The second LED flashes to indicate that a DTMFcharacter has been received and decoded.

BATTERY (SentriVoice+)The lead-acid battery is a “maintenance-free” type. The battery consists of lead-calciumplates, emerged in a sulfuric acid gelatin and sealed in a strong epoxy/plastic case. Asdischarge occurs, the sulfuric acid solution reacts with electrodes to form lead sulfate andwater. During charging, the process is reversed. If over charging occurs, oxygen andhydrogen gases are produced. The lead plates first absorb the excess oxygen to form leadsulfate. If over charging continues, the battery will vent (at 1 to 6 PSI) the excess hydrogenand oxygen gas. The battery can be used in any position. No electrolyte leakage can occur.

Batteries should be stored between -15° to 40° C. Batteries may be operated while thetemperature is between -15° to 50° C. Batteries should be charged at temperatures between0° to 40° C. The voltage range for “float” charging a nearly charged battery is between 13.6and 13.8 VDC. The voltage range for “fast” charging a depleted battery is between 14.6 and15.0 VDC. Note that the fast charging voltage should only be applied for a limited time periodotherwise over charging may occur drying out the electrolyte gel. Charging a battery attemperatures below 0° C or above 40° C may cause excessive current to flow into the battery,may cause over charging and may eventually cause heat deformation of the case. Atemperature compensated charger should be used to charge this battery unless used in acontrolled (indoor) environment.

CHARGER (SentriVoice+)The battery charger board consists of four main blocks: Battery Charge Regulator, PowerLoss Detect, Low Voltage Detect, and Low Voltage Switch. See Figure 6-2.

The Battery Charge Regulator detects when the battery has shorted cells (BATT < 5 VDC),when the battery is in a low charge state (BATT < 12 VDC), and when the battery is fullycharged (BATT > 13 VDC). If the Charge Regulator detects a shorted cell, then the regulatorwill be disabled and the battery will not be charged. When the battery is in a low charge state,

the Regulator will increase the charge current by increasing the charge voltage. When thebattery is fully charged, the Regulator will provide a trickle charge.

The Power Loss Detect circuit will notify the system when the charger input (V+ IN) voltagefalls below about 11 VDC. This signal (PWR LOSS) is LOW to indicate normal operation,and HIGH to indicate power loss.

The Low Voltage Detect circuit controls the Low Voltage Switch to protect the battery fromexcessive discharging. During normal operation, the switch will provide a maximum of 7.0Afrom the battery (BATT) terminal to the load (V+ OUT) terminals. When AC power isremoved, the battery will begin to discharge. The low voltage detect circuit will keep theswitch ON until the load voltage < 10 VDC. When AC power returns, the battery will beginto charge. The detect circuit keeps the switch OFF until the battery voltage (BATT) > 12VDC.

OPTIONAL CIRCUITSThe options for the SentriVoice+ include up to 80 seconds of voice, two control relays, andspecial software to provide the paging options. The software of the paging feature isdiscussed fully in Section 8 and will not be covered here. The hardware to support the pagingcapability is the same as for the DTMF output.

Options for the SentriVoice include 10, 20, 40, or 80 seconds of voice, relays, and pagingoptions.

Optional Voice CircuitsThe recorder and playback component for voice signals is the TC8830, U5. The componentstores and plays back voice information in its RAMs, U1 and U2. The voice output of theTC8830 is produced with an internal 10-bit DAC. It is transmitted through a bandpass filterand then transmitted through U14D to the radio or local telephone output.

Voice input can be recorded from either the radio or local telephone. The radio voice inputsignal travels through a bandpass filter to the voice component. The telephone voice inputsignal is buffered through U16C, gain of 1, and then through the same bandpass filter as forthe radio input. Typically, the telephone input offers the clearest voice recordings. Note thatthere is no adjustment for either voice output or voice input to the local telephone. If a localtelephone is attached to J1, voice is directly output through U14D.

Optional Relay CircuitsThe two control relays offer the user two modes of operation: normally open or normallyshorted to ground. These modes are selected with JP9 for control relay 1 and JP10 for controlrelay 2.

7. TROUBLESHOOTING

OVERVIEWAlways first check that power is correctly applied to the unit (observe DC polarity) and thatinput power is between 10.5 and 16 VDC or 9 VAC.

The troubleshooting topics that follow are grouped according to the portions of theSentriVoice that they affect.

Local Phone

No tones when phone key is pressed Verify that you are using a DTMF telephoneplugged into the connector (RJ11) in thecenter of the board.

No response when access code is entered Use correct access code, factory default is10#1987. Also make sure that the receiveaudio from the radio is disconnected. Thisaudio can interfere with the telephone audio.

To verify operation, check the DTMF validoutput on the DTMF decoder LED. ThisLED should flash with each telephone keypress. If some keys do not work, adjust R57.Remember that the * key can be used to clearany false DTMF signal by canceling theinput.

Check that the COR input is the correct level;use JP3 to assist if necessary.

Programming by Radio

No response when access code is entered See above. Also adjust receive audio levelusing the potentiometer (see Section 3).

Troubleshooting

7-2 025-9302

RS-232 Serial Port

Nothing displayed on terminal screenMixed up characters on screenNo response to keyboard input

Check your cable connections. With power toboth the terminal (or PC) and the unit, youshould measure -6 to -12 volts DC to groundon the Transmit and Receive, pins 3 and 4 onJ3. The most common problem is theconnections are reversed. Pins 2 and 3 on theterminal are usually Transmit and receive.Also, verify the communications port andbaud rate.

Double characters displayed when akeyboard entry is made

Make sure the communications port is set forecho off and in full-duplex mode.

Intermittent communications Make sure the terminal and the unit aresharing a common ground.

Voice

No voice or voice message quits early If your total recording time exceeds theamount of storage purchased, there will be novoice on playback of the higher numberedmessages recorded.

IN CASE OF DIFFICULTYIn case of installation or operation difficulty, call Zetron at (425) 820-6363. Please have theserial number of the unit and/or the Zetron order number. If the call is made from theinstallation site by the installer or radio technician, the problem can usually be solved overthe telephone.

WARNINGShipping the lead acid battery and/or battery charger back to the factory inside theNEMA enclosure will cause damage to the enclosure, battery and/or charger. Zetronwill charge the sender for any damage incurred as a result.

8. OPTIONS

TWO-TONE SEQUENTIAL (OR PLECTRON) PAGING OPTION

OperationEach alarm can generate up to three capcodes of Motorola two-tone paging tones (or standardPlectron tones) prior to the voice message.

The Two-Tone option for the Model 1516 and 1517 provides the standard Motorola and GEtone selections listed in Table 8-1. The Plectron option for the Model 1516 and 1517provides the standard Motorola and Plectron tone selections listed in Table 8-2.

Programming Two-Tone and Plectron FormatsIn addition to all of the programming operations discussed in Section 5, the programming ofthe Two-Tone and Plectron paging options makes particular use of the following commands.

CapcodeMenu Path: Main Menu | Paging Menu | Capcode n where n = 1, 2, or 3DTMF Syntax: 9xg1t1g2t2 where x = selects which capcode to program

g1 = selects tone group containing the first tone t1 = selects a specific tone from the g1 tone group g2 = selects tone group containing the second tone t2 = selects a specific tone from the g2 tone group

Range: x = 1, 2, or 3, g1/g2 = 1 to 9 (or A to E), t1/t2 = 0 to 9 or Arefer to Table 8-1 for the Two-Tone option, and Table 8-2 for the Plectronoption

Default: All capcodes are blank (i.e. g1t1g2t2 = 0000, setting the tone informationof a previously programmed capcode to all zeros will clear it)

This command is used to enter the necessary information to define a paging sequence inwhichever format is installed in the unit.

Each input can have up to three capcodes assigned. In RS-232 programming, the specificinput being programmed is selected from within the Paging menu. In DTMF programming,this command must be preceded by the “1at” command to select an input to programcapcodes for.

Capcodes are entered as group 1 tone 1, group 2 tone 2. The valid entries for tone groups are1 to 9 and A to E as found in Table 8-1 and Table 8-2. The valid entries for tone numbers are0 to 9 and A, also found in Table 8-1 and Table 8-2. If you have Plectron capability in yourunit, use Table 8-2. To disable a capcode, enter 0000 for group 1 tone 1 and group 2 tone2.

Tone groups A through E are programmed by entering *1 through *5 respectively. Forexample, if capcode 1 is to be 1881.0/2468.2 from tone groups D and E (refer to Table 8-1),the command would be 91*49*59.

Two-Tone TimingMenu Path: Main Menu | System Setup | Two-Tone TimingDTMF Syntax: N/ARange: 0 to 8Default: 0

This command is used to select which one of the available two-tone timing schemes is usedto make pages. This is a global setting; i.e. the same timing is used for all pages. There is noDTMF command for this parameter.

This sets the timing of the paging tones being transmitted according to Table 8-3.

Table 8-3. Two-Tone Sequential Standard Timings

ExampleThe following example is presented to help you gain familiarity with the two-tone format.

We want to send two pages for alarm 1, capcode 1 is 330.5/569.1, capcode 2 is 944.1/881.0(refer to Table 8-1). The programming would be:

110 This selects alarm 1 (and sets message type to “full”).

911020 This programs the first capcode for alarm 1. It setsfirst tone to: group 1, tone 0 (330.5 Hz)second tone to: group 2, tone 0 (569.1 Hz)

928999 This programs the first capcode for alarm 2. It setsfirst tone to: group 8, tone 9 (944.1 Hz)second tone to: group 9, tone 9 (881.0 Hz)

Please note that all timing is 1/0/3 — 1 second for the first tone, 3 seconds for the secondtone with no gap between them. Timing can be changed only via RS-232 programming.

A group call of 8 seconds of a single tone can be done by programming that tone as both thefirst and second tone in the capcode.

Options

025-9302 8-5

Tone groups A through E are programmed by entering *1 through *5 respectively. Forexample, if capcode 1 is to be 1881.0/2468.2 from tone groups D and E (refer to Table 8-1),the command would be 91*49*59.

If you have Plectron capability in your unit, be sure to use Table 8-2 for tone groupsinformation.

FIVE/SIX-TONE OPTION

OperationEach alarm can generate a lead-in sequence followed by one to three tone groups. The lead-insequence can take one of two forms, depending on whether or not the lead-in tone is enabled.(See Figure 8-1)

The lead-in delay can be programmed in the range of 20 to 2500 mSec.

With the lead-in tone disabled, the SentriVoice or SentriVoice+ will wait for the lead-indelay time before it begins to generate the first tone group. When enabled, the lead-in tone isgenerated during the lead-in delay. A gap of two tone-periods (silence) follows the lead-intone and precedes the start of the tone groups.

Each tone group consists of from one to seven tones and can be followed by an optionalstatus tone gap and status tone. The tone period can be programmed for 20 to 100 msec. Thestatus tone gap can be either 0 mSec (no gap) or in the range of 20 to 500 msec, and thestatus tone can last from one to five tone periods.

Each tone group is separated from the next by 2 tone periods of silence (the inter-group gap).

If the status tone gap is programmed to 0 msec, the status tone immediately follows the lasttone in the tone group.

The tone groups can contain the digits 0-9 or G (group call). The status tone can be any tone0-9 or A-F. SentriVoice or SentriVoice+ automatically generates repeat tones for the tonegroup, but not for the status tone.

DTMF ProgrammingThe Five/Six-Tone options cannot be programmed with DTMF - an RS-232 terminal isrequired. All parameters that are not specific to Five/Six-Tone can be programmed withDTMF as described in Sections 3 and 5.

Group 1, 2, 3 Each tone group can contain from one to seven tones. Only digits 0-9and G (for the group tone) are allowed.

In a tone group, all digits following the first group digit must also begroup digits. For example, SentriVoice or SentriVoice+ will acceptthe tone group “123GG” but not “123G4”.

After entering Group x tones, the programmer is prompted:“No status tone or 0- 9, A - F:”

For each tone group, the status tone can be set to any of the tones 0-9or A-F, or it can be disabled.

Tone set Each of the 16 tones, 0-9 and A-F, can be programmed individuallyto any frequency from 300 Hz to 3000 Hz. The default setting is theCCIR tone set with a few additional tones. Refer the manufacturer’sliterature for the appropriate tones for your radios or pagers. Table8-4 shows the default tone group along with several standard tonegroups.

Tone period The tone period is the duration of each tone and is programmablefrom 20 to 100 mSec. Default = 100 mSec.

Status tone gap The status tone gap can be set to 0 or programmed in the range of 20to 500 mSec. Default = 100 mSec.

If the status tone gap is 0, it will, if enabled, immediately follow thelast tone in the tone group. However, automatic repeat tonegeneration does NOT apply to the status tone.

Status toneduration

The valid range is 1 to 5 tone periods. Default = 2 tone periods.

Extended groupcall

The extended group call format can be enabled or disabled. Whenenabled, the duration of the first group tone in a tone group isextended to 3 tone periods. When disabled, all group tones are justone tone period long. The default setting is disabled.

POCSAG PAGING OPTION

OperationEach alarm can page up to three different POCSAG pagers prior to the voice message. Tone-only, numeric display, or alphanumeric display pagers are supported at either 512 or 1200baud.

When you are editing POCSAG capcodes from RS-232 programming, there are severalprogramming functions that are unique to the POCSAG paging option. The latest version ofthe firmware (released with this version of the manual) allows you to review the currentlyentered capcodes and function codes without editing the memory. Table 8-5 contains a briefdescription of these editing features.

Review a function code = press TAB key to proceed to function code field without altering the capcode

Function Code Program a new function code = type in digit (1-4), press ENTER

Exit without changing code = press the ESC or TAB key

Note: Although it is possible to skip entering a newcapcode and still enter a function code, trying toassign a function code to a currently “disabled”capcode only results in the function code beingforced to the default setting (1).

Function codes are used to determine the pager’s response to the page it just received.Possible responses are things like: to buzz, to beep, or to vibrate.

Default: all three capcodes are blank

If the capcode is being entered using DTMF programming, then this command must bepreceded by the “1at” (see the description in Section 5).

If the capcode is being entered using RS-232 programming, you should review the functionsfor the ESC, TAB, and ENTER keys described in Table 8-5. The function code may only beaccessed by means of the capcode command. You may either enter the capcode digits andpress ENTER to reach the function code, or just press the TAB key to proceed to the functioncode field without altering the capcode.

To disable a capcode, you either press the ENTER key without entering any digits first, or inDTMF programming enter nothing but zeros for the capcode. (i.e. 9x0000000b) You willreceive an “Illegal Entry!” prompt or error “buzz” to indicate that “0000000” is not a validcapcode, and the capcode will be disabled.

Function CodeMenu Path: Main Menu | Paging Menu | Capcode xDTMF Syntax: see Capcode where b = function codeRange: 1 to 4 (you must review the pager’s programming)Default: 1

In DTMF programming, the function code is entered at the same time as the capcode.

In RS-232 programming, whether the capcode was just filled in or was programmedpreviously, you must pass through the capcode entry screen in order to reach the functioncode entry screen.

You may not enter a function code for a capcode that is blank. Trying to assign a functioncode to a blank capcode results in no change; the function code remains at default.

The function code merely sends a digit to the pager that invokes some reaction that the pageris programmed to perform. You must review the programming of the particular pager you arecalling to determine which function code you need to send the pager.

Figure 9-1. DTMF Command Structure

Progress tones follow DTMF commands if the user unkeys before pressing another key.There are four different audio tones:

1. A progress tone for a successful DTMF entry2. An error tone for a faulty input or undefined command3. An alert tone that precedes a voice message4. An exit tone signaling that you are exiting from programming mode

Note: It is intended that the user enter the preamble, the unit ID, and the DTMFcommand/parameters all as a single string. There is no provision for a prompttone to occur between the preamble/unit ID and the command/parameters.

OPERATIONAL MODE COMMANDSThe following commands must be preceded by pp#u (see Section 5).

INITIALIZATION MODE COMMANDSThese commands do not apply if you are using a PC or terminal via RS-232 port to program.To enter the initialization mode, momentarily ground TP2 right after power up. (TP2 islocated between the corner of U12 (microprocessor) and U13.)

0xx program prekey time10d program number of digits in unit ID, valid settings are 1 or 22uu program unit ID uu, valid range is 00 to 99 (you must enter two digits, see

To exit initialization mode, press either the # or key (or the A, B, C, or D keys if yourkeypad offers access to fourth-column DTMF characters). Another way to exit theinitialization mode is to cycle power on the unit.

Note: In the case of the Unit ID, it is important to recall that the digits represent anaddress, not an amount. Thus the unit does not consider an entry of “03” to beequal to an entry of “3”. The command “2uu” always requires two digits to beentered; however, it is the command “10d” that determines how the number isevaluated for login purposes. If a single-digit ID code has been selected, thenonly the least significant digit (the second ID digit entered) is used for the IDcode. The command “10d”may be used to at any time without having to re-enterthe setting for “2uu”.

Note: The COR input is pulled high through an internal 10-kΩ resistor. If you programthe COR level to active high, you may need to connect JP3, grounding the CORinput to allow programming. JP3 pulls the COR input to ground.

10. PROGRAMMING WORKSHEET

OVERVIEWThis programming worksheet will guide you through the process of setting up SentriVoice orSentriVoice+ the way you want it to work. It is intended to allow you to think about thethings you will do to make SentriVoice or SentriVoice+ perform the tasks you want done. Itwill also provide a record of its configuration for your files.

Programming is accomplished by using a telephone or radio with a DTMF pad or by using aPC with a terminal emulation program or a terminal via an RS-232 port.

Some SentriVoice or SentriVoice+ features will not be applicable to your system and otherfeatures, while used, should not be changed unless your needs are different from the defaultvalues preset at the factory. Go through this worksheet and determine the appropriate valuesfor your system and enter them in the underlined space. If you plan to use the default value,leave the space blank.

INITIALIZATIONThis subsection covers information that is system specific. If you are programming from aDTMF telephone or radio, these functions are part of the initialization of SentriVoice orSentriVoice+. See Section 3 for more information.

How many digits are in the unit ID number?

10_ Default = 1. (1 or 2).

SentriVoice or SentriVoice+ unit ID numbers are used to identify which unit is beingcalled on a multi-unit system. The maximum number of SentriVoice or SentriVoice+units that can be addressed is 99. A single digit ID is adequate to specify one to ninedifferent units. By specifying two digits, the unit ID can range from 01 to 99.

What is the unit ID number of this SentriVoice or SentriVoice+?

2_ / 2_ _ Default = 1. (1 to 9 or 01 to 99).

What command preamble will be used for this SentriVoice or SentriVoice+?

3_ _ Default = 10. (any two DTMF digits).

The preamble is used in the day-to-day DTMF operational access to SentriVoice orSentriVoice+ to acknowledge alarms and so forth.

Programming Worksheet

10-2 025-9302

What will be the programming security code?

4_ _ _ Default = 987. (100 to 999).

This code provides protection against unauthorized access to the programming mode.The first digit must not be 0 (zero).

Should COR be set active low?

600 COR active low ___. This is factory-set default.601 COR active high ___.

Should this SentriVoice or SentriVoice+ be set for conventional radio operation?

701 Conventional radio ___. This is factory-set default.700 Trunking radio ___.

How many times should the voice message repeat in an alarm cycle?

9y Voice repeats ___. Default = 3. (1 to 9).

GLOBAL INFORMATIONThis subsection covers global information that applies to all eight inputs. See Section 5 formore information.

How often should an alert be resent until it is acknowledged?

4_ _ Default = 30 minutes. (1 to 99 minutes).

In other words, how long (in minutes) should the interval between alerts be?

How many times should the alert be resent?

5_ _ Default = 10 times. (0 to 15 times).

Should an audio alert tone (siren) go out before the report?

603 Siren on ____. This is factory-set default.602 Siren off ____.

How many times, in every 24-hour period, should the all’s well message be sent?

61_ Default = 0. (0 to 8 times).

The all’s well message gives confirmation that the SentriVoice or SentriVoice+system is functioning properly.

Programming Worksheet

025-9302 10-3

INPUT SPECIFICThis subsection covers information that is input specific. Thus, each of the eight inputs mustbe programmed with these commands. See Section 5 for more information.

The following chart has space for writing down the parameters and voice messages relatingto each input. The numbers preceding the blanks are the DTMF commands for that entry.

The following parameters should be entered on the chart if they differ from the default. n =input (1 to 8).

What type of alarm should this input be?

2xn Default = 1. (1 to 6)

The types of alarms x are defined as follows:

1 = Normally open (NO) and an alarm is triggered on a closure.2 = Normally closed (NC) and an alarm is triggered on an opening.3 = Momentary NO and an alarm cycle is started on a closure.4 = Status alarm, i.e., a different voice message is transmitted for an opening than for a

closure. Transmission is triggered by a change is state.5 = NO with clear message. Operates similar to type 4, but the message sent on a closure

repeats multiple times, and the message sent on an open only transmits one time.6 = NC with clear message. Operates similar to type 4, but the message sent on an open

repeats multiple times, and the message sent on a closure only transmits one time.

How long, in seconds, is the voice message?

3mm Default = 0. (0 to 80).

If alerts are to include a voice message, the length of message allowed for each alarmmust be established. If the input is an alarm type 4, 5, or 6 (status), the messagelength is equally divided between the first and second message. The total time for allmessages is 80 seconds.

Write down the voice messages on the lines provided. If the alarm type is 4, 5, or 6, the firstmessage is sent on opens, and the second message on closures. If the alarm type is 1, 2, or 3,the first message is sent.
