Alarm Verification Facility (AVF) can be used selectively on each alarm point to reduce false alarms by requiring
an alarm condition to be present for a period of time before an alarm is generated. AVF works as follows.
1.
Receive 1
st
alarm signal. (Do not do anything with the alarm signal)
2.
Initiate a 15 second reset on the point which generated the alarm.
3.
Once the 15 second reset has completed, start a 120 second timer.
4.
If an alarm comes in within the 120 seconds it is to be treated as a real alarm.
5.
If the 120 second timer expires, return the zone back to its normal condition.

A timed AZF can be used where normal latching detectors are required to be used in a duct probe application.
1.
Timed AZF’s function as follows:
2.
Once the point goes into alarm, generate an alarm. (You can combine with AVF too if you wish)
3.
Retest the zone for continued alarm condition every 15 seconds by powering down and re-powering the
detector.
4.
If the alarm is still present, keep zone in alarm, otherwise return zone back to normal condition after 60
seconds.
Note:
Minimum time in alarm condition is 75 seconds (15 seconds to first test plus 60 seconds after alarm clears)
