2. Description
Alarms
The detector reports alarm in the following cases:
glass break detection (registering a low frequency sound (impact) followed by a high
frequency sound (glass break) in less than 4 seconds),
opening the tamper contact (tamper alarm).
Test mode
Placing a jumper across the TST pins as shown in Fig. 2 will activate the test mode. When
the detector is running in the test mode, the LED indicator is enabled and the detector will
report an alarm on registering a glass-break sound (high frequency sound).
Periodic transmissions
Every 15 minutes, the detector sends a transmission containing information on the status of
the tamper contact and battery. Periodic transmissions are used to monitor presence and
operation of the detector.
