Device Loop Card

Installation InstructionsModel DLC

INTRODUCTION The Model DLC Device Loop Card from Siemens Industry,Inc., is the interface for connection of FireFinder-XLS smokedetectors, manual stations, monitor devices, and controldevices to the FireFinder-XLS System. The DLC uses onenetwork address on the system. The application programthat is loaded into the on-board microprocessor controls theDLC operation.

The DLC contains 12 LEDs for diagnosis of problems.Ground fault detection is provided by loop.

All field devices connected to the DLC are addressed andtested using the Device Programming Unit (DPU).

OPERATION The DLC initializes, operates, and maintains all devicesresiding on the loop. The DLC communicates all relevantdevice and event information, such as alarms and troubles,to the System CPU. The sensitivity of any intelligent smokedetector and the logic functions of any intelligent outputdevices can be checked and adjusted from the PMI throughthe DLC. All information about the devices on the loop canbe displayed on the PMI. The DLC allows the Systempolarity insensitive devices to be connected withoutgenerating errors.

The DLC supports only one loop (two isolated parallelzones) of up to 252 FireFinder-XLS intelligent field devicesas well as device accessories (relay bases, audible bases,and remote lamps) in any combination. The microprocessorcontrols the on-board isolator to isolate either zone fromthe loop if one of them is shorted. When one zone isisolated from the loop, the other zone will still work.

The on-board microprocessor provides the DLC with theability to function and initiate alarm conditions even if themain FireFinder-XLS CPU fails.

Controls and Indicators The front panel of the DLC contains one reset switch, 12 LEDs, and three HNETaddress switches, as shown in Figure 1. A reset switch is located on the top of thefront panel. Pushing the reset switch re-initializes the DLC operation.

The LEDs follow the reset switch and their functions are defined as follows:

POWER (Green) Normally ON. When illuminated, indi-cates the power for the DLC is applied tothe card.

CARD FAIL (Yellow) Normally OFF. When illuminated, indi-cates the card microprocessor has failed.

HNET FAIL (Yellow) Normally OFF. When illuminated, indi-cates that the HNET communication withthe DLC has terminated and the cardgoes into degrade mode.

GND FAULT (Yellow) Normally OFF. When illuminated, indi-cates that the DLC has detected either anegative or positive ground fault on itsfield wiring.

ALARM (Red) Normally OFF. When illuminated, indicatesthat the DLC has detected an alarm.

TROUBLE (Yellow) Normally OFF. When illuminated, indi-cates that the DLC has detected atrouble on its field wiring.

CLASS A OPEN–ZONE 1 (Yellow) Normally Off. When illuminated, indi-cates a Zone 1 wire is open if the loopwas set to Class A.

CLASS A RETURN–ZONE 1 (Yellow) Normally Off. When illuminated, indi-cates a Zone 1 return wire is reversed ifthe loop was set to Class A.

SHORT–ZONE 1 (Yellow) Normally Off. When illuminated, indi-cates a Zone 1 wire short.

CLASS A OPEN–ZONE 2 (Yellow) Normally Off. When illuminated, indi-cates a Zone 2 wire is open if the loopwas set to Class A.

CLASS A RETURN–ZONE 2 (Yellow) Normally Off. When illuminated, indi-cates a Zone 2 return wire is reversed ifthe loop was set to Class A.

SHORT–ZONE 2 (Yellow) Normally Off. When illuminated, indi-cates a Zone 2 wire short.

Three rotary dial switches at the bottom of the front panel are used to set the HNETnetwork address of the DLC. All field devices connected to the DLC are addressedand tested using the Device Programming Unit (DPU). Refer to the DPU Manual,P/N 315-033260 for further information.


P/N 315-033090-123

PRE-INSTALLATION Set the three-digit HNET network address for the DLC using the three rotary dialswitches located near the bottom of the front panel. (Refer to Figure 1 for thelocation of the switches.) The address for the DLC must be the same as the addressselected for it in the Zeus Programming Tool. To set the address, turn the pointers oneach of the three dials to the numbers for the selected address. For example, if theaddress is 123, set the pointer for the HUNDREDS dial to “1”, set the pointer for theTENS dial to “2”, and set the pointer for the ONES dial to “3”. The range of allowableaddresses is from 001 to 251 (leading zeros must be used).

INSTALLATION The DLC plugs perpendicularly into one slot in the CC-5 card-cage via two 96-pin DINconnectors and can occupy any slot in the card cage. (Refer to Figure 2.)

Insert the DLC card into the card guides rightside up(lettering on the front panel is legible)

Slide the card in until the card edge connectors contactthe receptacles on the motherboard.

Verify that the DIN connectors of the card and the card-cage aligned properly. The card can only plug in onedirection to the card cage, if it does not align, DO NOTFORCE the card.

Place thumbs on the front panel adjacent to the captivescrews and gently apply even pressure on the card untilthe connectors seat in the receptacles on themotherboard.

Secure with the captive screws.

WIRING

Remove all system power before installation, first battery then AC. (To power up,connect the AC first, then the battery.)

All field wiring to the DLC is connected to the terminal blocks of the CC-5 card cageslot in which it is installed.

To Connect External Wiring

1. Loosen the screw of the terminal by turning it counterclockwise.

2. Insert the wire into the side of the terminal block.

3. Tighten the screw of the terminal block by turning it clockwise.

Connect +24V from the PSC-12 to terminal 17 and -24V from the PSC-12 to terminal18 of the slot in the CC-5 where the DLC will be installed. (Refer to Figure 3.)

The DLC circuit can be wired Style 4 (Class B) or Style 6 (Class A). On-boardswitches controlled by microprocessor allow selection of Class A or B without usingjumpers for Class B. The DLC field circuit wiring does not require twisted, shielded

wire. It can be installed in conduit containing low voltage power, notification appli-ance circuits, audible and speaker zone circuits, and RS-485 and other data circuitswithout restrictions.

Electrical connections for the two zones are shown in Figure 4. The wiring style is setin the Zeus Programming Tool without using external jumpers. Once the wiring styleis set, both zones will be set to the same style.

Do not wire the two zones in different styles.

If the return wires are reversed in each zone (Class A), the CLASS A RETURN LEDwill turn on. Switch the two return wires to remove this trouble. Eliminate all othertroubles before completing the installation.

COMPATIBILITY 1. The DLC supports only FireFinder-XLS intelligent devices. The compatibilityidentifiers for the compatible devices are the model numbers listed in Table 1for UL 864 and in Table 2 for UL2572. Use any combination of those listed ineither Table 1 or Table 2, as applicable.

2. The DLC supports one loop (with 2 isolated zones) of up to 252 FireFinder-XLS intelligent field devices. Up to 252 devices can be distributed in eitherzone, but the total number is limited. For example, if 100 devices are inZone 1, then the number of the devices in Zone 2 must be 152 or less.

3. All circuits are power limited to NFPA 70 per NEC 760. The DLC supportsthe use of 12-22 AWG non-shielded, non-twisted, thermoplastic fixture wirewithout conduit, if permitted by local building codes.

4. No end of line device is required.

5. Total circuit resistance of each zone must not exceed 50 ohms when 252devices are loaded into one zone. (Refer to the chart on page 7.)

Maximum capacitance: 0.5μF between line+ and line-1.0μF between line and chassis

6. T-tapping is not allowed on Class A loops.

7. All models are UL and ULC listed.

8. The FDOT421/OH921 multi-criteria smoke detectors are exchangeabledetectors for the HFP-11 in XLS systems when DLC firmware 5.05.0006 orhigher is used. Use the DPU programmer/tester with the FC-20 systemoption to program the FDOT421/OH921 to replace an HFP-11 detector inthe DLC line. The XLS system will recognize the FDOT421/OH921 as anHFP-11 and display HFP-11 in the system’s PMI interface and Zeus program-ming tool. The DLC supports all functions and specifications of the HFP-11for FDOT421/OH921 except the following:

• Sensitivity Adjustment• IEC Compensation Report• Sensitivity Change through PMI• ASD Disable (ASD can be temporarily disabled at the PMI when testing

is required.)• ASD Disable with Alarm Verification• Thermal Element Permanently Disabled• ASD Duct with Alarm Verification

An EEPROM trouble is generated when ASD is disabled or Alarm Verifica-tion is enabled.

The FDOT421/OH921 is NOT compatible with the following accessories:

AD-11P ADBH-11 AD-HR DB-HR AD2 Series Duct Detectors
