FC440SB and FC440AIB Addressable Sounder Base and Addressable Sounder VID Base

The FC440SB is an addressable sounder base specifically for use with the FireClass addressable detectors. The base incorporates a fire alarm sounder that carries its own address so it can be monitored and controlled from the fire alarm control panel, which is independent of the detector fitted to the base. The two-wire digital loop provides both power and communications for the sounder and detector.
