The AA alarm has to be acknowledged within an acknowledge time and the AA alarm has
to be reset within an investigation time, otherwise the output for routing equipment (Fire
brigade TX) will be activated.
During the acknowledgement and investigation times:
 If a fire alarm is activated by a detector / zone not programmed for Alert
Annunciation or if fire alarm is activated by a manual call point, the output(s) for
routing equipment (fire brigade tx) will be activated.
 If "Multiple alarms allowed within same zone" is set via EBLWin, more than one AA
alarm is allowed within that zone.
 "Number of zones" can be set via EBLWin. Normally, only one zone with AA alarm
is allowed but up to four zones can be used.
Acknowledgement and Reset are done on the Alert annunciation unit 1736. Programmable
output "Alert Announcement Activated" for indication and programmable inputs "Alert
Announcement Acknowledge" and "Alert Announcement Reset" can also be used.
The Acknowledgement time can be set to 0-120 seconds.
The Investigation time can be set to 0-9 minutes.
14.12 Alert Annunciation Applications
14.12.1 Alarm Acknowledgement Facility (AAF)
The AAF function is similar to the "Alert Annunciation function" as explained in chapter
14.11 page 111. The COM loop module used to achieve the AVF function is called Alarm
Acknowledgement Module (AAM).
The AAM can be either surface mounted in the supplied white box or recess mounted in a
single gang box. It enables the occupant to control the smoke detection inside the sole
occupancy unit within a pre-determined time delay. The AAM is used in conjunction with
the sounder base 3379. The AAM provides the occupant with a facility to avoid the
unwanted alarms within the occupancy e.g. cooking fumes, smoking aerosol spray steams,
etc.
Each AAF Zone consists of one or up to five analogue smoke detectors (4400 / 4401),
one or up to five sounder bases 3379 and one AAM, all connected to the COM loop.
