Main siren for DVS90
The DVS90 primary siren emits a loud sound when the alarm is triggered.
The primary siren is part of the DVS90 alarm system.
Only one main siren can be installed with each DVS90 alarm system. Additional BackUp sirens can be connected through one of the alarms outputs.
Remember to synchronize the alarm after installation. If this is not done, the siren may not function as intended.
