INTRODUCTION
The information provided herein covers the range of product know as the "Sensor 902" series. The
range of equipment is designed to meet the requirements of BS5839 Part 1 : 1988 and includes panels
of 1, 2 and 4 zones. The units are intended for surface mounting. They may be recessed by using a
‘Flush-in’ surround.
The details provided here are for Standard Products and any variations will be dealt with at the end of
this manual.
When servicing, it is important to note that replacements of parts should be limited to the largest
complete assembly. A complete printed circuit board should be replaced rather than individual
components on that board. This requirement does not extend to such items as switches, etc., which
may be replaced as single items.
It must be stressed that service, maintenance and part replacement should only be carried out by
persons familiar with Fire Detection Systems, and with suitable qualifications for handling electronic
equipment.
In the event of the need to contact the manufacturers for spares or additional service information, it is
essential that the serial number of the equipment is quoted.
When installing the equipment to the instructions herein, you are also reminded that careful attention
should be paid to the relevant British Standard for Fire Alarm Installation, and the prevailing site
conditions.

PRINCIPLE OF REVERSING THE VOLTAGE BETWEEN THE NORMAL
MONITORING CONDITION AND THE ALARM CONDITION.
2.3.1.
Testing for short-circuit indication.
Note:- The following test should be carried out using a power resistor (100 ohms, rated
at least 2 watts) rather than a direct short-circuit which, in the advent of an inadvertent
alarm on a zone, would blow the sounder fuse.
Place the resistor, momentarily and in turn, between the Hi and Lo terminals of each
Sounder circuit and check that the relevant internal SHORT lamp and the front panel
FAULT lamp both illuminate and that the buzzer operates.
2.3.2.
Testing for open-circuit indication.
Momentarily remove each sounder circuit fuse, in turn and check that the relevant
internal OPEN lamp and front panel FAULT lamp both illuminate and that the buzzer
operates.
2.4.
ZONE DETECTOR CIRCUITS
IT SHOULD BE NOTED THAT FOR “SAV-WIRE” VERSIONS, THE ZONE
SOUNDER CIRCUITS OPERATE ON THE PRINCIPLE OF REVERSING THE
VOLTAGE BETWEEN THE NORMAL MONITORING CONDITION AND THE
ALARM CONDITION.
2.4.1.
Testing for open circuit indication.
a) Momentarily remove one end of the ‘End of Line’ resistor from Zone 1 and check
that the relevant internal OPEN lamp ant the front panel FAULT lamp both illuminate
and that the buzzer operates.
b) Repeat the above for each of the remaining zones.
2.4.2.
Testing for Detector Removed indication.
Note:- The following test should be carried out using a 3300 ohm 1/2 watt resistor.

CONNECTION AND TESTING
3.1.
ZONE WIRING
3.1.1.
Remove the ‘End of Line’ resistor from Zone 1.
DO NOT REMOVE THE SOUNDER ‘END OF LINE’ RESISTORS OR
TERMINATE THE SOUNDER CIRCUIT CABLES AT THIS TIME.
3.1.2.
Terminate Zone 1 detector wiring.
3.1.3.
Fit the ‘End of Line’ resistors at the extreme end of each detection circuit and check
that all the detectors and call points are correctly fitted.
3.1.4.
Repeat in turn for all zones.
3.1.5.
If any of the zonal FIRE lamps or FAULT lamps are illuminated, it would indicate that
a detector has been incorrectly wired or has been operated.
OR
A manual alarm call point has been inadvertently operated or incorrectly connected.
OR
A sounder (in the case of Say-Wire) has been incorrectly connected.
OR
An open circuit, short circuit or a low resistance exists between the zone cables.
OR
A zonal fuse has blown.
3.1.9.
Should the operation of the FIRE or FAULT lamps not be as a result of the operation
of a detector or a manual call point (or sounder), then the zone wiring should be
investigated one section at a time.
3.1.9.
Firstly check that only one zone is malfunctioning. If more than one zone is at fault,
disconnect the cables from all other faulty zones and connect their respective ‘End of
Line resistors to the terminal blocks.
3.1.9.
Investigate the internal fault lamps to establish the nature of the fault. Remember to set
the CONTROL keyswitch to the MASTER position and depress the RESET/LAMP
TEST press button to clear any bogus FIRE conditions.
3.1.9.
If the detector OPEN lamp is illuminated, this would indicate that either the ‘End of
Line’ resistor has not been terminated correctly or that an open circuit has occurred in
the zone wiring, either in the cable itself or at a point of connection to an ‘alarm
initiating’ device (or a sounder).
Page 5
3.1.10.
Should, after investigation, the ‘End of Line’ resistor be found to be properly
connected, then remove it and place it across the zone terminals. The Fault lamps
should go out.
3.1.11.
If the detector SHORT, detector REMOVED or FIRE lamps are illuminated, then this
would indicate that a short circuit or low resistance exists in the zone wiring, either in
the cable itself or at the point of connection to an ‘alarm initiating’ device (or sounder).
3.1.12.
Set the CONTROL keyswitch to the MASTER position and momentarily depress the
RESET/LAMP TEST push button.
3.1.13.
If the detector SHORT, detector REMOVED or FIRE lamps do not go out, then carry
out a detailed inspection of this section of cable and rectify the fault.
3.2.
SAV-WIRE
Note:- The maximum alarm load per zone must not exceed 1/2 amp. The total alarm
load for all outputs must not exceed 1 amp.
3.3.
COMMON SOUNDER WIRING
Note 1:- The maximum alarm load must not exceed 1 amp, which may be distributed
across the two Common Sounder circuits and the Zonal ‘SAV-WIRE’ Sounder circuits
if used.
Note 2:- Remember that at least one sounder must be fitted to each of the Common
Sounder circuits to meet the requirements of BS 5839 Part 1, 1988.
3.3.1.
The cable resistance in the sounder circuits should be calculated in accordance with the
operating voltage range and the current consumption of the sounders to be used.
Note:- The specified voltage range provided by the panel to drive the sounders will be
within the range 21.5 volts to 27.0 volts.
3.3.2.
Remove the ‘End of Line’ resistor from Sounder 1.
3.3.3.
Terminate Sounder 1 wiring.
3.3.4.
Fit the ‘End of Lines resistor at the extreme end of this sounder circuit and check that
all the sounders are correctly fitted.
3.3.5.
Ensure that no alarm condition is being indicated on the control panel and also check
that the CONTROL switch is not set to the EVACUATE position. Remove the key if
in doubt.
3.3.6.
If either of the internal sounder FAULT lamps are illuminated, it would indicate that a
sounder has been incorrectly wired.
OR
An open circuit, short circuit or a low resistance exists between the sounder cables.
3.3.7.
A faulty circuit should be investigated one section at a time.
3.3.8.
Investigate the internal fault lamps to establish the nature of the fault.
Page 6
3.3.9.
If the internal sounder OPEN lamp is illuminated, this would indicate that either the
‘End of Line’ resistor has not been terminated correctly or that an open circuit has
occurred in the wiring, either in the cable itself or at a point of connection to a sounder
device.
3.3.10.
Should, after investigation, the ‘End of Line' resistor be found to be properly
connected, then remove it and place it across the sounder terminals. The Fault lamps
should go out.
3.3.11.
If the internal sounder SHORT is illuminated, then a short circuit or low resistance
exists between the sounder cables.
3.3.12.
Proceed to the first ‘sounder’ device and disconnect the wiring between it and the
panel.
3.3.13.
If the sounder SHORT lamp does not go out, then carry out a detailed inspection of
this section of the cable and rectify the fault. Reconnect the wiring to this first
‘sounder’ device.
3.3.14.
Repeat steps 3.3.13. and 3.3.14. at successive ‘sounder’ devices until the sounder
SHORT lamp goes out.
3.3.15.
Repeat steps 3.3.2. to 3.3.4. and 3.3.5. to 3.3.14 for Sounder 2.
DO NOT PROCEED TO THE NEXT SECTION UNTIL A STABLE FAULT-FREE
SITUATION HAS BEEN ESTABLISHED.
3.3.16.
The sounders may now be tested by setting the CONTROL keyswitch to EVACUATE.
The sounders should be individually checked for correct operation. After this test,
return the CONTROL keyswitch to the centre (off) position.
