Application
Compatible to all FD720 point detectors.
For surface supply line until cable 8 mm in diameter.
The signal base and the detector compose a unity, which already has a base and is mounted on ceilings,
e.g. in hotel rooms, hospitals and nursing homes.
Function
The sounder base serves for acoustic alarming in the addressed FS720 fire detection system.
In case of a fire alarm, the signal base triggers an acoustic signal in parallel to the flashing of the detector
LED.
Synchronized of acoustic signals with all other alarm sounder and sounder beacon devices in the same
detector line (C-NET).
