Installation & Operation Guide

Documentation Issue 2.1


An Introduction to Intercall 400. The Intercall 400 System is an advanced addressable call system which provides a simply reliable

communication system between residents and staff using a simple cabling structure. All calls are displayed

with text descriptions (e.g. GND FLOOR BED 4) and all call points have the facility to generate two levels of

call; patient call and staff emergency call. The calls are displayed audibly and visually on the staff display

units and any number of these units may be located throughout the establishment to alert staff and display the

calling location(s). The Intercall 400 structured cabling is very simply and only requires a common 2 core

connection to operate.

An Introduction to Intercall 500. Using the same principles as the Intercall 400 System, the Intercall 500 system also features a two way

intercom facility between the calling resident and the staff. The intercom channel is private between the

calling resident and the staff display, which has accepted the call. In addition, a intercom paging system is

provided between all displays. The Intercall 500 structured cabling requires a common 4 core connection to

operate. We recommend Belden screened cable for larger installations – See Installation Guide.

L541 Standard Call Point

An L541 Call Point is required at every location where a call is to be generated where

no intercom facility is required (i.e. toilets/bathrooms or non speech systems). The unit

features three levels of call (Call, Emergency and Reset) with re-assurance LED. The

jack socket will accept an input from pear leads, pressure mats, radio triggers and a

host of triggering devices. The unit should be mounted 1300mm from the floor level.

L521 Intercom Call Point.

An L521 Intercom Call Point is required at every location where a call is to

be generated where the intercom facility is required. The unit features three

levels of call (Call, Emergency and Reset) with re-assurance LED. The

jack socket will accept an input from pear leads, pressure mats, radio

triggers and a host of triggering devices. The unit should be mounted

1300mm from the floor level.

L418 Standard Display Unit.

An L418 Display Unit is required at every location where the calls are to

be shown and the audible alarm is to sound. There is no limit to the number

of display units on the system and we recommend 1 display for every 10

call points. All units feature 32 character LCD display with backlight and

integral audible alarm.

L518 Intercom Display Unit

The L518 Intercom Display Unit is required at every location where the

calls are to be shown, the audible alarm is to sound and the intercom

facility is required. There is no limit to the number of display units on the

system and we recommend 1 display for every 10 call points. All units

feature intercom & display to display paging facility.

L541DK Door Monitoring Point

Doors can be monitored using the L541DK similar in appearance to the L541, the unit

features a keyswitch to enable and disable the alarm function allowing the door to be

opened by authorised personnel only. The unit generates a standard level of call and

this is indicated with the integral re-assurance LED.


L416 Addressable Overdoor Light

Overdoor Lights are located above the bedroom doors to show the status of the call

point within the room. They can show standard call, emergency call and nurse present

indication using light patterns shown on the 6 high brightness LED indicators.

L414 Remote Sounder Unit

Remote Sounders are used to provide additional alarm tones in areas where there is no

requirement to show the location of the calls. The sounder is synchronised with the

Intercall 400 series displays and may be used with the Intercall 500 system however,

the tones are different from the L518. The units are fitted with on-board relay contacts

and may be used to drive external equipment.

L417 400 Series Master Power Supply.

The L417 Power Supply provides the power and master data signals for the Intercall

400 system only. It has space for a backup battery which must be ordered separately.

The unit also includes a mains failure audible alarm.

L517 500 Series Master Power Supply.

The L517 Power Supply provides the power and master data signals for the Intercall

500 system only. It has space for a backup battery, which must be ordered separately.

The unit also includes a mains failure audible alarm.

L737 Booster Power Supply.

The L737 Power Supply is only required on larger systems or where large amounts of

existing cabling is being re-used. The unit has space for a backup battery, which must

be ordered separately. The unit also includes a mains failure audible alarm.

RX1 Remote Radio Fob Trigger And Receiver (Fixed Installation)

The RX1 Remote trigger comprises a trigger fob unit and a receiver unit which is mounted on a single gang

plate. The fob triggers and receivers are normally despatched in coded pairs, additional triggers and receivers

are available but you will need to specify the required codes(s) if they are to work with existing units. The

receiver unit requires a connection to the system two core and an additional connection to trigger a call point

in the same way as a ceiling pull switch. INSTALLATION: Run an extra two core wire from RX1 to call

point. (See also RX2)

RX2 Portable Remote Radio Fob Trigger And Receiver (Portable)

The RX2 Remote trigger comprises a trigger fob unit and a receiver unit which simply plugs into a 13Amp

socket and the jack socket of the Call Point it is intended to operate. The fob triggers and receivers are

normally despatched in coded pairs, additional triggers and receivers are available but you will need to specify

the required codes(s) if they are to work with existing units. INSTALLATION: The unit requires no fixed

installation.

TX1 Additional Radio Fob Trigger

The TX1 is an additional trigger which can be coded to operate any RX1 or RX2 providing the code of the

receiver is known. This code can be found on the back of the receiver unit and inside the ANC1ART Fob unit

an example of the code is UK123456. The trigger size is 35 x 45 x 10mm.

L427 Alphanumeric Pager Interface Unit

The L427 is physically identical to the L407 and has very similar electronics and board layout. Install and

connect as per the L407 instructions with the following amendments: 1. The interface unit powers the radio

transmitter with 12vDC (as if does with the printer). 2. The parallel data lead plugs into the interface board as

the L407 but the lead has a different connector on the pager end. 3. There is no display or date and time set up.

The pagers come supplied with their own instruction books.


PS1 Plug In Pull Cords

The PS1 is a small pull cord which plugs into the jack socket on the call points and can be used to make a call

where a pear lead would not be suitable . It is fitted with a 0.25 inch jack plug and a 50cm cord which hangs

down from the front of the call point.

NP2 and NP4 Pear Leads

The Pear leads plug into the jack socket on the call points and enable residents to call from a position away

from the call point. They are available in two lengths 2 metre and 4 metre.

PM1 Pressure Mat The Pressure Mat plugs into the jack socket on the call points and is another way in which a call can be

generated. This unit must be placed under a carpet or similar primary surface and must not be walked

on directly. The mat size is 600mm x 300mm.

S1 Soft Touch Air Switch

The Air Switch plug into the jack socket on the call points and enable frail residents to call as they are very

sensitive but also have the advantage of being water resistant and can be operated in the bath. There is a 2

metre air pipe which connects to a 4 metre lead which is terminated in a 0.25 inch jack socket.

MR1 Magnetic Reset Key

The Magnetic Reset Key is for use with the ANC1CPM Call Point where RESET and EMERGENCY to only

be operated with the use of this magnetic key. The unit can be attached to a key ring.

AD1 Adapter Plates

The Adapter Plates are used to mount a Call Point over a double gang backbox to minimise installation

disruption. It has four mounting lugs which enable it to cover a double gang plate vertically or horizontally.

Please note this item is only suitable for mounting Call Points.

Intercall 400 and Intercall 500 Inter-compatibility. Intercall 400 and Intercall 500 components may be mixed on the same system, however the L517 Power

Supply must be used when this practised is adopted. All Intercall 400 components are fitted with the two

Network terminals while all Intercall 500 components are fitted with four (4) network terminals. A simple

Intercall 400 system which does not require the Intercom facility must consist of 1 x L541 Call Point, 1 x

L418 Display Unit and 1 x L417 Power Supply. A basic Intercall 500 system with intercom must consist of 1

x L521 Intercom Call Point, 1 x L518 Intercom Display Unit and 1 x L517 Power Supply Unit. When a L541

Call Point is accepted on a Intercall 500 display, the SPEECH OPEN wording is displayed but the intercom

channel is not operational as the L541 does not have the required intercom circuitry.

Mixing L518 and L418 Display Units & L414 Remote Sounders. Providing an L517 Power Supply is used, a single system may contain L518 and L418 display units and L414

Remote Sounder units. It must be noted that the sounder from the L418 and the L414 will be different from the

chime tones generated by the L518 units. In addition, when the TALK button is pressed on any L518 unit to

accept the call silence the alarm and open the intercom channel, the L418 and L414 units will continue to

sound in the normal way. Emergency calls will generate a similar tone on all units and the L418 and the L414

units may be configured to sound the alarm tone for the Emergency call level only.

Intercall 400 and Intercall 500 Cable. The Network cable should be 4 core (for Intercall 400) or 6 core (for Intercall 500) stranded security alarm

cable (7/0.2) as it is flexible and allows extra cores in the event of cable failure. All volt drop and capacitance

calculations within this leaflet were carried out using this cable, other types of cable will have different

characteristics and may affect wiring limitations described elsewhere in this leaflet.

Intercall 500 alternative Cable. To improve the audio quality on the Intercall 500 system, a screened Belden cable may be used to separate the

digital and audio signals. We only recommend BELDEN 8723 or similar with two individual screened cable

pairs, one to carry the + and – power and data lines and the other pair to carry the A & B audio pair. The

screen must be connected to the network –ve terminal at every cable junction.

Installation Guide.

The INTERCALL system uses a digital addressing system which allows all power, data & audio requirements

to be transmitted down a single cable, we call this cable the ‘Network’. Call Points, LCD Displays, Overdoor

Lights, and Remote Sounders are connected to this cable. All units are fitted with a positive (+) and negative (-

) terminal which connects to this cable in a chain format. (See fig 3.1) Intercall 500 audio units are also fitted

with (a) and (b) terminals for the audio pair.

Fig 3.1 Power Supply, Call Points, LCD Displays, Overdoor Lights & Sounders connect to the ‘Network’

The Call Points are fitted with two DIL switches, which are used to set the text and number for that unit. The

Power Supply transmits a series of addresses. After each address it waits for a reply from the call point. The

displays look at both the signals from the power supply and the Call Points and decide the status of the call

points. Overdoor lights are intelligent and look for replies from the call points and show a pattern depending

on the information they receive.

A Basic System.

Every system must contain one L417 or L517 Power Supply, at least one L418 or L518 LCD Display and at

least one L541 or L521 Call Point. We recommend the addition of a back up battery LBAT which fits into the

Power Supply case in the event of mains failure.

Intercall 400 and Intercall 500 Cable. The Network cable should be 4 core (for Intercall 400) or 6 core (for Intercall 500) stranded security alarm

cable (7/0.2) as it is flexible and allows extra cores in the event of cable failure. All volt drop and capacitance

calculations within this leaflet were carried out using this cable, other types of cable will have different

characteristics and may affect wiring limitations described elsewhere in this leaflet.

Intercall 500 alternative Cable. To improve the audio quality on the Intercall 500 system, a screened Belden cable may be used to separate the

digital and audio signals. We only recommend BELDEN 8723 or similar with two individual screened cable

pairs, one to carry the + and – power and data lines and the other pair to carry the A & B audio pair. The

screen must be connected to the network –ve terminal at every cable junction.


Planning an Installation.

Fig 3.2 Several Spurs run from the Power Supply

• Locate the Power Supply in a central location of the building and begin running several cable spurs from

this point via every network device on the spur. (See Fig 3.2) If you are unsure as to the final length of cable always split the load and run extra spurs.

• The length of each spur must be calculated in accordance with the specification detailed in section 3.3

• When mixing Audio units and non audio units, we recommend only running the A and B cables to the

audio units only and not via all network devices to improve the audio quality.

• Ceiling Pull switches are wired back to a call point. They do not connected to the Network.

• Avoid running cables alongside mains cables, fluorescent lights, electrical switch-gear, lift machinery and

motors and high voltage cables.

• Never use two cores within a cable used for other systems. E.g. Fire Alarm, Telephones etc.

Replacing an existing System – using the existing wiring.

The INTERCALL system is ideally suited for the replacement of existing hard wired nursecall system, using

the existing cabling but please note the following considerations.

• Study and make notes about the existing system.

The most common problems occur when the old system is removed before the wiring is understood. We need

to identify two cores common to all parts of the system which are usually the supply lines. Look for legends

on the printed circuit boards (0v, GND, +12 + etc)

• Remove all parts of the old system from the wiring.

Another common problem is where parts of the old system are still connected, a remote sounder, bell or buzzer

in another part of the system.

• Make sure the old power supply is switched off and disconnected from the system.

Do not attempt to keep the old system running on the same cables as you are installing the new system, you

are most likely to damage both systems and delay completion.


• Beware of Multi-core cables.

Multi-core cable is often used on older systems where every call point requires an individual connection back

to the display panel. See Fig 1.3 80 pair cable (160 cores) is quite common. If you are using multi-core cable

you should only use two cores within the multi-core length. Because of the nature of this system, every time

we add an additional + and – in the cable we are doubling the cable loading on the system. For example if we

had 10 pairs of cable used within a 20 metre cable length this would equate to 200 metres of cable loading on

the system. If you will be using multi-core cable on an installation, we recommend quoting for an additional

L737 Booster Power Supply.

Fig 3.3 Using existing wiring, extra displays installed virtually anywhere on the network

On the existing wiring installation above, we have joined all + & – , A & B connections together at the power

supply and fitted an additional display on a new cable run.

New Build Installation.

The INTERCALL system offers the most straightforward installation for new build jobs and diagram 1.2

shown a typical installation.

• Locate the Power Supply in a central location of the building and begin running several cable spurs from

this point via every network device on the spur. See Fig 3.2 If you unsure as to the final length of cable

always split the load and run extra spurs.

• Choose an accessible position for the power supplies which will allow system programming to be carried

out and for the mains failure alarm to be heard.

• If your system requires an Boosting Power Supply. Locate this either alongside the Master Power Supply

or on the next floor.

• We do not recommend cable rings for the Network as they add to cable loading and make fault finding

more complicated.

• We recommend fitting a FJB1 Fused Junction Box on the output of the power supplies which will

protect the system from complete shut-down if there is a cable fault on one of the spurs.


Wiring Limitations. There are two pitfalls with any system of this nature, cable volt drop and cable capacitance. This system uses

very little current and an advanced transmission system protocol which reduces the effects of cable

capacitance but both can be avoided completely by following a few simple rules defined below.

Maximum Spur Length Calculator

To avoid cable volt drop problems, by following the simple guide below, it is possible to calculate

the maximum cable spur run from the power supply. Simply add the current unit values for all

devices on a spur and using the chart below, look up the maximum spur length.

Note 1: This limit is for cable volt drop purposes and assumes that units are located at regular intervals along the length of the cable. If you suspect

the system may have several active calls at one time or you need to exceed this value, use larger cable (0.75mm2)

All calculations are based on standard security alarm cable with a conducting area of 7/0,2.

• Do not ‘Double up’ Network cabling - it will double cable capacitance.

• If you need more than 1Km (1000m) of Network cable - Split the system with a Booster PSU.

• If the system is requires more than 100 Current Units - Split the system with a Booster PSU.

The diagram below shows how the spur length calculation is applied to a typical installation with the power

supply L417 or L517 shown as PS. The L737 Booster PSU (shown as BP) would be necessary if the total of

current units exceeds 100 or there will be more than 1000m of Network cable.

First Fix. We only recommend four core stranded security alarm cable for new installations as this is flexible and allows

extra cable cores in the event of cable damage or failure.

Determine the position of the power supply and begin running cables from that point via every addressable

unit, on the spur. The maximum amount of number of cable ‘spurs’ and the maximum length of each spur

depends on the amount of equipment you require on the system. Please read ‘General Wiring Considerations’

& ‘Wiring Limitations’ for more information.

Due to the wide variety of fixing possibilities, the Intercall system is not supplied with back-boxes. We

recommend the following available from your local electrical wholesaler or supplier.

Second Fix. This section covers the connecting and basic testing of all parts of the system. It is intended as a brief

overview for connecting and testing for the first time and does not go into great detail on each individual unit.

Detailed information on each individual unit is covered elsewhere in this leaflet.

Connecting the Master Power Supply. (L417 or L517)

• Connect the mains supply to the Power Supply and switch on.

• The alarm will sound for about 4 seconds while the unit carries out a power on reset.

• If the supply is unstable, due to flat battery, a short on the output wiring or fluctuating mains supply, the

unit will not reset and the alarm will continue to sound.

• After the reset, the following light should be visible: The Yellow ‘Mains OK’ LED, the Green ‘DC OK’

LED* and the red ‘Micro’ LED will be flashing at once a second.

• If your are running from the battery, the Yellow LED will not light & the mains failure alarm will beep

every 5 seconds.

• If the Green LED is not lit check the fuse is intact and the fuse holder is tight around the fuse connections.

• Do not switch the system on by connecting the battery as the surge may blow the fuse.

• Switch off and connect one ‘leg’ of the installation so that we can test the operation of the units.

• Once the units are connected, test the system as per the instructions in section ‘Basic System Test’.

* If fitted

ALWAYS CHECK THE POLARITY OF THE BATTERY AND ALL UNITS BEFORE SWITCHING ON!

All network devices are fitted with reverse polarity protection and the PSU fuse will blow or the power

supply will shut down if any unit is connected incorrectly.

Basic System Test – Power Up.

Before the system is tested, the call point(s) address switches will need to be set. If you are testing a single call

point set up we recommend setting the unit to BEDROOM 1. (4way switch all ON) (7way switch 1 OFF, All

others ON) There is a complete list of text & number settings in this guide. If you will be using overdoor

lights, set the switches on the overdoor light to the same setting as the call point.

• Connect the Master Power Supply and test as per the relevant page and switch the mains supply on.

• When power is applied to the call points, the re-assurance LED will flash green three times to indicate the

unit has reset and is running correctly.

• When power is applied to the display units, the display will show the software version (e.g. V2.01)

followed by the standing text INTERCALL 400 or INTERCALL 500 depending on the system.

• When power is applied to the overdoor lights they illuminate the start up pattern.

Basic System Test - Call Test. (Intercall 400/500)

Once the system has powered up correctly, the following test can be carried out:

All items marked * are optional and may not be fitted on your system.

• Press the CALL area on a call point.

• The red re-assurance LED will flash slowly on the call point.

• After a short pause, the display will sound and the LCD display will be showing BEDROOM 1.

• * The overdoor light assigned to BEDROOM 1 will show the standard call signal. (Falling pattern)

• Press the RESET area on the call point to reset.


Basic System Test – Emergency Call Test. (Intercall 400/500)

Once the system has powered up correctly, the following test can be carried out:

L737 Universal Booster Power Supply Unit. The Booster Power Supply unit is designed to increase the permitted number of units and quantity of cable that

can be used on any one system. Only one master supply may be connected on any one system but several

booster units may be connected as required. The input of the all booster unit(s) must be connected directly to

the output circuit of the master and not ‘daisy chained’. (See fig 3.2) You must not make any connection that

will effectively ‘short out’ the booster input +ve and output +ve. When installing a system that requires a

booster, always load the booster(s) output with more cable than the master. You may locate the Booster

Power Supply either alongside the master unit or on the next floor/wing etc.

u = Switch up (Towards ON) D = Switch down (Away from ON)


Multi-bedded Text The Intercall 400/500 system can be configured to display multi-bedded text, this is used where there are more than

one call point in a room. A call point displays the bed number and the room number. e.g. BED 1 ROOM 1. You can

have all combinations from BED 1 ROOM 1 to BED 3 ROOM 62. The way in which call points are set up for

multi-bedded text is different from the standard text and this is described below.

Set the text switches to (1) Duuu(4)for call points in the range of BED 1 ROOM 1 to BED 3 ROOM 31. The first

five number switches (1 to 5) set the room number in the same way as they set the number settings for standard text

and the remaining two switches (6 & 7) set the BED number between 1 and 3.

Alternatively, set the text switches to (1) uDuD(4)for call points in the range of BED 1 ROOM 32 to BED 3

ROOM 62. The first five number switches (1 to 5) set the room number in the same way as above but 1 becomes

32, 2 becomes 32 and so on. The remaining two switches (6 & 7) set the BED number between 1 and 3.
