Silent Alarm
A zone programmed to be silent will not trigger the HORN SPEAKER, RELAY, STROBE or
EDMSAT outputs. The dialler and all other programmable outputs will function as per their
particular programming.
Sensor Watch
Sensor watch gives the control panel the ability to recognise that detection devices may have
stopped working. This is a feature that monitors the operation of a zone over a programmed
time period. Refer to "LOCATION 218 - 219" on page 129 for programming sensor watch
time.
This value determines how many 24 hour periods a zone may remain continuously sealed
before it registers as a sensor watch fault. The number of hours required to fulfil these 24 hour
periods is only calculated while the system is in the disarmed state. Every time the system is
armed the counter pauses calculating. Sensor watch will continue calculating the next time the
system has been disarmed.
Example
If the sensor watch time is programmed for two days in a situation where a premises is armed
for twelve hours and disarmed for twelve hours each day, it will take four days before a zone
can register as a faulty sensor watch zone.
