The BiWire base sounder and base sounder visual alarm device (VAD), can be used both with a detector or as a standalone device.
The base sounder and base sounder VAD incorporate a detector mounting base, allowing a detector to be fitted directly to the base or, alternatively, a cover plate can be used to provide a dedicated, discreet, standalone device.
Both options are suited to applications where ambient noise is high, including schools, retail units, healthcare, offices and nursing homes, and a wide variety of industrial environments.
