Numens is pleased to announce the release of our new 641 addressable audio/visual alarm devices. These multi-tonal alarms are compatible with Numens 2-wire addressable fire detection and alarm systems. Four distinct alarm tones can be selected during installation.
641 alarm devices are loop-powered. 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 devices can be connected to each alarm zone loop. Weatherproof models are included in the range.
Designed for compliance with EN 54-3 and EN 54-23 Standards, the 641 range of addressable audio/visual alarm devices provide fire detection and alarm system designers with a premium product for life safety applications.
