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 B501BH sounder base is used with System Sensor 200 and Series sensor heads. Refer to the appropriate manual for information on sensors. 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. When not used as a supplementary evacuation system external 24 VDC supply shall be treated as a component of main power supply system and shall fall under the require- of the main power supply system per NFPA 72.

Electrical boxes must be square by at least 11 inches deep – 21 inches is rec- 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.

Then, slide the bare end of the wire the clamping plate, and tighten the clamping plate Do NOT loop the wire under the clamping plate (See 3). zone wiring of the sensor base should be ch
