I 3825 Ohio Avenue St Charles Illinois 60174 FAX 630 377 6495 AND MAINTENANCE INSTRUCTIONS Bases Diameter Height less base and sensor Temperature Range Humidity Range Ratings Current Current Ripple Voltage Capacitance Input Current Requirement Output Delay Time inches 152 mm inches 19mm lb 145 g to 140 to 60 to 95 non condensing to 32 VDC mA maximum mA maximum of supply voltage maximum than 90 dBa measured in anechoic room at 10 feet 3 meters volts 85 dBa minimum measured in UL reverberant room to 5.7 sec 1 TERMINAL LAyOUT INSTALLINg thoroughly read the System Smoke Detector Application Guide which detailed information on detector spacing placement zoning wiring special applications Copies of this manual are available from System Sen NFPA 72 and NEMA guidelines should be observed This manual should be left with the owner user of this equipment The detector used with these bases must be tested and main regularly following NFPA 72 requirements The detector used with bases should be cleaned at least once a year DESCRIpTION B401BH 2 sounder bases is intended for use with System Sensor 400 plug in sensor heads in conventional 2 wire plug in systems Refer to manuals for the maximum allowable number of units per loop The requires an external 24VDC nominal supply with reverse polarity The connections of the external supply terminals 1 and 2 and the loop terminals 3 4 and 5 are isolated in the B401BH 2 to prevent interaction between them Supply Positive Supply Negative loop of horns can be made to sound by reversing the polarity of the external When the associated system is NOT used as a supplementary evacua system the external 24VDC supply must be treated as a component of the power supply system with the result that it falls under the requirements NFPA 72 TERMINALS Function 3 4 and 5 are used for the communication initiating circuit WIRINg gUIDELINES wiring must be installed in compliance with the National Electrical Code all applicable local codes and any special requirements of the authority jurisdiction using the proper wire size The conductors used to con smoke detectors to control panels and accessory devices should be color to reduce the likelihood of wiring errors Improper connections can a system from responding properly in the event of a fire Negative V V In V Out signal wiring the wiring between interconnected detectors it is recom that the wire be no smaller than AWG 18 However the screws and plate in the base can accommodate wire sizes up to AWG 12 The of twisted pair wiring or shielded cable for the power and loop is to minimize the effects of electrical interference on the initiat loop electrical connections by stripping about 3 8 insulation from the end the wire Then slide the bare end of the wire under the clamping plate and the clamping plate screw Break the wire at each terminal to ensure the connections are supervised as shown in Figure 2 2 NOT loop the wire under the clamping plate Check the zone wiring of the detector base before the detector heads are Perform continuity base polarity and dielectric tests on the wiring detectors and alarm system control panels have specifications for al supervision current Consult the control panel manufacturer speci for the total loop current supervision allowed for the control panel used before wiring the detector loops 3 TypICAL WIRINg LAyOUT A OPTIONAL WIRING INIT INIT 5 1 INSTRUCTIONS shorting spring in the base will disengage automatically when the detec head is removed from the base NOT remove the shorting spring since it reengages as the detector head is into the base completing the circuit typical wiring for a two wire conventional system is shown in Figure 3 Re to this diagram as needed while wiring the base into the system Figure 3 shows external 24V supply polarity when loop system is in standby NOT alarming It is recommended that the base be completely wired before mounting Figure 4 Attach the base directly to an electrical box using the screws with the box Then use the plastic screw covers supplied with the to cover the screws sounder base is 1.1 inches 28 mm deep Electrical boxes must be 4 inches mm square by at least 1 1 2 inches 38 mm deep 2 1 8 inches 54 mm recommended testing notify the proper authorities that the smoke detector system is un maintenance and that the system will be temporarily out of service Dis the zone or system undergoing maintenance to prevent unwanted alarms and bases must be tested after installation and following periodic the B401BH 2 as follows Test the conventional detector head following the procedure in its man The B401BH 2 should sound approximately 0.75 to 5.7 seconds after detector alarms Reverse the polarity of the external 24 VDC supply This should cause base in the loop to sound after approximately 0.75 to 5.7 seconds 5 1 5 1 EOL A OPTIONAL WIRING 4 MOUNTINg TO AN ELECTRICAL BOx SUPPLIED SUPPLIED refer to insert for the Limitations of Fire Alarm
