System Sensor B200SR-IV Addressable Sounder Base (Ivory)

The System Sensor B200SR-IV Addressable Sounder Base (Ivory) is intended for use with intelligent systems. The sounder base requires an external 24 VDC power supply. The connections for the external power supply and the communication loop are isolated to prevent electrical interaction between them. The sounder base is capable of producing either the distinctive three-pulse temporal pattern (ANSI Temporal 3) fire alarm signal now required by NFPA 72 for commercial and residential applications, or a continuous tone, by simply removing the included jumper from the device. The B200SR-IV is designed to be compatible with existing installations of B501-Series sounder bases. Mount the B200SR-IV mounting plate directly to an electrical box. The plate will mount directly to 4" square (with and without plaster ring), 4" octagon, 31/2" octagon, single gang or double gang junction boxes.
