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 is done on the Alert annunciation unit 1736. A programmable
output "Alert Annunciation Activated" for indication and programmable inputs "Alert
Annunciation Acknowledge" and "Alert Annunciation 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.

Alert Annunciation Applications
17.13.1
Alarm Acknowledgement Facility (AAF)
The AAF function is similar to the "Alert Annunciation function" as explained in chapter
17.12 above. The COM loop module used to achieve the AAF 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 same COM loop.
Each AAM is configured as an AAFC
detectors. If the analogue value of one or more smoke detector in an AAFC zone reaches
the alarm level, the alarm acknowledgement process starts and the sounder base will be
activated.
