Numens is pleased to announce the release of our new 447 non‑addressable audio/visual alarm devices. These multi-tonal alarms are compatible with Numens 2-wire non-addressable and addressable Numens fire detection and alarm systems. Four distinct alarm tones can be selected during installation.
Activation is initiated upon connection of the operating voltage, allowing connection to either a switched supply at the control and indicating equipment, or via an output module.
The range includes weather-proof models.
Designed for compliance with EN 54-3 and EN 54-23 Standards, the 447 range of non-addressable audio/visual alarm devices provide fire detection and alarm system designers with a premium product for life safety applications.
