The AA alarm has to be acknowledged within an acknowledge time
and the AA alarm has to be reset within an investigation time, else the

During the acknowledge 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 WinG3,
more than one AA alarm is allowed within that zone.

"Number of zones" can be set via WinG3. Normally only one
zone with AA alarm is allowed but up to four zones can be
allowed.

1736 or Alert annunciation controller 1740. A programmable output
("Alert Annunciation Activated") for indication and programmable
inputs ("Alert Annunciation Acknowledge" and "Alert Annunciation
Reset") can also be used.
The Acknowledge time can be set to 0-120 seconds.
The Investigation time can be set to 0-9 minutes.

equipment must not exceed 10 minutes (i.e. Acknowledge time +
