Figure 22. Alarm Acknowledgement Facility units.
Function (see also the flow chart in the following figure):
- One of the detectors in an AAF zone reaches its fire alarm level.
The AA Process starts and the AAF buzzer sounds.
- An Acknowledgement Period starts
(AP=0-120 sec. -- programmable).
- If it is a false alarm, acknowledge the alarm on the AAFC before
the AP is ended.
- After acknowledgement an Investigation Period starts and the AAF
buzzer is silent
(IP=0-9 min. -- programmable).
If all the detectors in the AAF zone becomes normal again (i.e. goes
below the fire alarm level respectively) during the IP, the AAP ends.
If the AP or the IP runs out during the AAP and any detector in the
AAF zone still is over its fire alarm level, normal fire alarm(s) will be
activated.
