Before Installing

Please read the System Smoke Detector Application Guide, which provides detailed information on sensor spacing. placement, zoning, wiring. and special applications. Copies of this manual are available from System Sensor. NFPA 72 and NEMA guidelines should be observed.

NOTICE: This manual should be left with the owner/user of this equipment.

IMPORTANT: The detector used with this base must be tested and maintained regularly following NFPA 72 require- ments. The detector should be cleaned at least once a year.

General Description

The B501BH sounder base is used with System Sensor 200 and 500 Series sensor heads. Refer to the appropriate man- ual for more information on sensors.

The sounder base is intended for use with intelligent sys- tems. Refer to the panel manual for the maximum allow- able number of units per loop. The sounder base requires an external 24VDC supply with reverse polarity capability. The connections for the external supply (terminals 1 and 2) and the communication loop (terminals 3 and 4) are iso- lated to prevent electrical interaction between them.

When the sensor’s visible LEDs are latched on for approx- imately 10 seconds, the associated horn sounds. A loop of horns can be made to sound by reversing the polarity of the external supply.

NOTE: When not used as a supplementary evacuation sys- tem, the external 24 VDC supply shall be treated as a component of the main power supply system and shall fall under the requirements of the main power supply system per NFPA 72.
