Alarm Acknowledgement Facility

Alarm Acknowledgement Facility

The Alarm Acknowledgment Facility (AAF) is a loop-powered addressable device that helps reduce the costly consequence of an unwanted alarm.

When an alarm condition occurs in a room as a result of an incipient fire, the sounder at the local AAF is activated. At this stage, the signal to the fire brigade and emergency warning system is inhibited and the 0 to 60 second “Alarm Acknowledgement Period” is commenced.

During the alarm acknowledgment period, the occupant of the room can acknowledge the alarm by pressing the silence button located on the AAF. Acknowledging the alarm will silence the local sounder and activate the 0 to 180 second “Investigate Period”. At the expiry of the investigation period, if the alarm still exists, a fire alarm will be announced which will activate the signal to the fire brigade and emergency warning system.
