before operating the siren and internal sounders.
The system then operates the siren and internal sounders for the programmed
Siren Time
.
Note:
Siren Delay
has no effect if
Alarm Response
(see above) does not require
communications or if a line fault is detected.

Siren Time
This option changes the length of time that the system operates the siren and internal
sounders during an alarm.

This applies to a siren wired directly to the control unit.
Radio sirens have separate maximum sounder durations to preserve battery life.
Please refer to the siren's installation instructions.
Any sounder assigned to two or more partitions uses the longest
Siren Time
of the
partitions the sounder is assigned to.

15mins. For INCERT approval, the minimum is 90s, and the maximum is 3mins.
