4.4.1 Alarm Verification Facility (AVF)
•
AVF Enabled
An alarm condition will not immediately signal an alarm state on the initial detector activation.
The zone with AVF enabled will reset the detector in that zone for the first 16-20 seconds

within the next verification cycle. This causes the zone alarm condition to remain on. If no
further alarm input was detected during the reset cycle, no alarm conditions will be generated.
•
AVF disabled
If the AVF is disabled, an alarm condition will be generated as soon as an alarm input is
detected.
