1. FACP removes power from all zones for 6 seconds, resetting all smoke detectors
2. Power is reapplied and a 12 second retard period begins, allowing detectors to
stabilize
3. During the 18 second reset/retard periods of steps 1 & 2, subsequent alarms by
the same zone are ignored
4. Alarms detected on any other zone during the retard period will cause the FACP
to immediately process the alarm
5. A confirmation period follows the reset/retard period. If an alarm occurs during
the confirmation period, on the zone which initiated verification, the FACP will
immediately process the alarm. If no alarm is detected during this confirmation
period, the FACP returns to normal condition
