YPES OF ALARMS
There are three types of alarms used in the Advisor MASTER system.
1.
Local alarm
2.
Alarm
3.
System alarm
Local alarm
•
It occurs when an area is occupied (that is, disarmed). For example, zones with
24-hour security have been activated: a firedoor has been opened.
•
The circumstances that caused the local alarm need to be checked and rectified by
someone on site. Consequently, the alarm does not need to be reported to a central
station.
See "
Resetting a local alarm
" for the procedure to identify, acknowledge and reset a local
alarm.
Alarm
•
The area is armed and one of its zones has been activated. For example, a door
lock has been forced open causing a siren to sound.
•
The area is disarmed and a 24 Hour zone was activated. For example: Hold-up
button is activated, tamper switch is open.
The exact type of alarm (siren, flashing light, etc.) depends on how the system has
been programmed.
The area LED on the panel identifies the location of the alarm.
See "
Resetting a zone in alarm
" for the procedure to reset an alarm.
