supply voltage maximum than 90 dBA measured in anechoic room at 10 feet 24 volts 85 dBA measured in UL reverberant room 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 Terminals Function External Supply Positive External Supply Negative Negative Comm Line In and Out Positive Comm Line In and Out Sounder Base Interconnect 3 and 4 are used for the communication circuit the B501BH directly to an electrical box using the kit supplied see Figure 2 sounder base is 1.1 inches deep 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 For best system per the power and wires and the communication wires should be twisted pair or shielded cable installed separate grounded conduit to protect the communication from electrical interference wire connections by stripping about 3 of insulation the end of the wire 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 checked before sensor heads are installed Check the wiring for continuity polarity in the base the individual sensor manual for the maximum sensor in temperature Instructions External supply shown in normal standby configura in Figures 4 and 5 wiring diagram for a typical 2 wire intelligent system is in Figures 4 and 5 the monitor module is supervising external supply and bases must be tested after installation and as an in part of periodic maintenance Test the B501BH as follows Before testing notify the proper authorities that the sensor system is undergoing maintenance and there will be temporarily out of service Disable the system un maintenance to prevent unwanted alarms If configured as in Figure 4 or 5 reverse the polarity of the 24VDC supply If configured as in Figure 5 turn the Intelligent Relay Module All B501BH bases on the should sound in approximately 10 seconds Latch the sensor LED on from the control panel That B501BH should sound in approximately 10 seconds There is approximately a 10 second delay built into the before sounding This delay is present whether control signal comes from the sensor or from the exter power supply polarity being reversed During automatic testing cycles the horn may sound if associated sensor is left in the test mode with LEDs on for more than 4 seconds Therefore it is neces to complete testing of each sensor within this 4 sec limit to prevent the horn from sounding 1 Terminal layout 2 Mounting 3 THIS B501BH ELECTRICAL BOX INCH SQUARE BOX 4 Wiring diagram Activates
