Honeywell B501BH Detector Base

The B501BH sounder base is used with System Sensor 200 and 500 Series sensor heads. Refer to the appropriate manual for more information on sensors. The sounder base is intended for use with intelligent systems. Refer to the panel manual for the maximum allowable number of units per loop. The sounder base requires an external 24VDC supply with reverse polarity capability or a relay module configured to reverse the power. The connections for the external supply (terminals 1 and 2) and the communication loop (terminals 3 and 4) are isolated to prevent electrical interaction between them. When the sensor’s visible LEDs are latched on for approximately 10 seconds, the associated horn sounds. A loop of horns can be made to sound by reversing the polarity of the external supply when configured. A loop of horns can also be made to sound by turning on the Intelligent Relay Module.
