3.3. DISARMING
When to use
The system should be disarmed before entering the building or premise (there
is no entry delay to the alarm).
Indications
The siren will beep twice and the blue strobe light will flash three times. The
siren will beep 12 times if the alarm has been triggered while the system was
armed.
3.4. PANIC Mode
When to use
This mode should be used when the user wishes to activate the siren possibly
used in an emergency situation.
What happens
The siren will sound and the blue light will flash to alert people in the area.
3.8. The Passive Infrared Detector
It is vital that the detector is tested carefully for each installation. At
25°Celsius, the detector should have a detection range of approximately 10
metres and a scope angle of 90°, i.e. 45° either side of the centre position
straight ahead of the lens.
