Alarm functions
Security alarm – this alarm is triggered whenever the contacts change from their normal state
(open or closed).
Entry & exit delay. Security alarms have a built-in 90-second exit delay. This allows 90 seconds
to leave an area and secure it during which time the sensor state is ignored. The entry delay is
optional and an alarm will not trigger the instant the sensors change state. They will trigger only
if the alarm has not been correctly reset within 90 seconds.
Social alarm. There are two types of social alarm. They work if there is no activity for a period
of 24 hours.
Type 1 will trigger if no one has used an extension for a period of 24 hours. It is cancelled as
soon as an extension is used. An external call is made if the internal alarm is not cleared within 1
hour.
Type 2 will trigger if an alarm loop has not changed state for 24 hours, such as a door contact,
unlike type 1 this alarm must be cancelled using the alarm cancel code. The alarm will ring on
all internal extensions initially. If the alarm is still not cleared for a further one hour and the
alarm loop does not change state then an external alarm call will be made.
