Sounder base

Stock no. S54319-F5-A1

Stock no. S54319-F5-A1

Compatible with all point detectors of the series Cerberus PRO.

The sounder base DBS720 and the detector compose a single unit, which already has a base and is mounted on ceilings, e.g. in hotel rooms, hospitals or nursing homes.

The sounder base serves for acoustic alarming in the addressed FS720 fire detection system. The sounder base can be allocated freely from the fire control panel to activate as required. It is not dependent upon an alarm signal from its associated detector.

Synchronized with all other alarm sounders and sounder beacon devices in the same detector line (C-NET).

No auxiliary power supply required; power is supplied via C-NET.

For recess supply wiring. For surface supply wiring, remove the corresponding breakouts for cable diameter up to max. Ø 8 mm.
