Description

The 901SB Addressable Sounder Bases provide a sounder function on MX addressable systems. Designed for indoor use, they require an associated detector in order to operate, as each base is controlled by its detector. The detector must be locked onto the sounder base using the detector locking device. Removal of the detector or loss of power to the loop will cause the sounder to cease sounding. It must be fixed to a flat ceiling or a suitable electrical backbox with 50mm fixing centres. The 901SB requires an external 24Vdc supply and is identified by a blue park clip. The 901SB supports ISO8201 T3 tones.
