Description
The Common Siren offers the possibility of transmitting the alarms of all alarm systems on one channel. The
alarm of the siren output behaves in the same way as the individual alarm sirens. If several alarms are on, they
are indicated wtih the following priority:
1. Smoke alarm
2. Intruder alarm
3. Water alarm
4. ISA alarm
The operation of the common siren is independent of whether a siren was configured in the individual alarm
system.
Note:
The signal time entered in the Common siren is automatically adopted by the individual sirens. This also
applies to reversed function.
If an alarm has been acknowledged or reset, the Mastergenerator also resets the signal of the common siren.
