Alarmline II Digital Linear Heat Sensor Cable Technical Manual 21
Simulated alarm test
Testing of the cable will trigger an alarm at the monitoring equipment – isolate
the monitoring equipment outputs as required.
To perform the test:
1. Ensure that the cable is connected to the monitoring equipment and that no
faults are present.
2. Place a short circuit across the end of the sensor cable.
3. Hold the short circuit in place until the relevant alarm condition appears on the
control panel.
4. Once the test has been completed, remove the short circuit and return all
control units to normal status.
Functional alarm test
If required a functional alarm test can be performed by attaching a spare length
of sensor cable to the end of the installed cable. This can then be heated to
generate an alarm condition.
Testing of the cable will trigger an alarm at the monitoring equipment – isolate
the monitoring equipment outputs as required.
To perform the test:
1. Fix a short length of cable (1 m, 3 ft.) between the end of the installed sensor
cable and the end-of-line device.
2. Using a suitable heat source subject the cable to sufficient heat to reach the
alarm temperature.
3. Confirm that the cable indicates the relevant alarm condition.
4. Remove the length of test cable and connect the end-of-line device to the
sensor cable before resetting the monitoring equipment.
