The 622 addressable audio/visual alarm control module is suitable for connection to 2-wire addressable fire detection and alarm systems.

622 is loop-powered and switches external DC 24 V power to non-addressable audio/visual alarm devices. The switched supply is supervised for open- and short-circuit conditions, and availability. Activation is initiated either by a dedicated initiation message from the control and indicating equipment or optionally when the control and indicating equipment enters the Alarm Condition. Up to 32 modules can be connected to each alarm zone loop.

The 622 range of addressable audio/visual alarm control modules provide fire detection and alarm system designers with a premium product for life safety applications.
