Installing read the System Smoke Detector Application Guide, provides detailed information on sensor spacing. place- zoning, wiring, and special applications. Copies of this are available from System Sensor. NFPA 72 and NEMA should be observed. This manual should be left with the owner/user of equipment. The detector used with this base must be tested maintained regularly following NFPA 72 requirements. detector should be cleaned at least once a year. Description B501BHT sounder base is used with System Sensor 200 500 Series sensor heads. Refer to the appropriate manual more information on sensors. B501BHT incorporates the distinctive three-pulse tempo- pattern fire alarm evacuation signal now required by NFPA for commercial and residential applications. sounder base is intended for use with intelligent systems. to the panel manual for the maximum allowable num- of units per loop. The sounder base requires an external supply with reverse polarity capability or a relay mod- configured to reverse the power as in Figure 5. The con- for the external supply (terminals 1 and 2) and the loop (terminals 3 and 4) are isolated to pre- electrical interaction between them. the sensor visible LEDs are latched on for approxi- 10 seconds, the associated horn sounds. A loop of can be made to sound by reversing the polarity of the supply when configured as in Figure 4 and 5. When as in Figure 5, a loop of horns can also be made to by turning on the Intelligent Relay Module. Supply Positive (+) Supply Negative ( ( Comm. Line In and Out (+) Comm.

Terminals Function 3 and 4 are used for the communication circuit. the B501BHT directly to an electrical box, using the kit, supplied (see Figure 2). sounder base is 1.1-inches deep. Electrical boxes must 4-inches square by at least 11 inches deep – 21 inches is A maximum space of 1 inch from the outside edge of electrical box to the inside edge of the drywall or ceiling is allowable. Guidelines wiring must be installed in compliance with the National Code and the local codes having jurisdiction and not be of such length or wire size which would cause base to operate outside of its published specifications. The used to connect smoke sensors to control panels accessory devices should be color coded to reduce the of wiring errors. Improper connections can prevent system from responding properly in the event of a fire. signal wiring (the wiring between interconnected sensors modules), it is recommended that the wire be no smaller 18 gauge (1.0 square mm). Wire sizes up to 12 gauge (2.5 mm) may be used with the base.
