    Product Features

    The sounder base DBS721 and the detector consist of a single unit already with a base and mounted on ceilings.

    For example, in hotel rooms, hospitals and nursing homes.

    The intermediate base is used for acoustic alarm in an addressable FS720 fire detection system.

    Each base has its own address and can be freely configured regardless of the respective detector.

    In the event of a fire alarm, the base triggers an acoustic signal.

    For all point detectors in the Cerberus PRO FD720 series.

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

    For flush mounting. For surface mounting, cable diameter up to 8 mm.
