to turn on Horn Output 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 zoning wiring and special applications Copies this manual are available from System Sensor NFPA 72 NEMA guidelines should be observed This manual should be left with the owner user this equipment The detector used with this base must be and maintained regularly following NFPA 72 require The detector should be cleaned at least once a year Description B501BH sounder base is used with System Sensor 200 500 Series sensor heads Refer to the appropriate man for more information on sensors sounder base is intended for use with intelligent sys Refer to the panel manual for the maximum allow number of units per loop The sounder base requires external 24VDC supply with reverse polarity capability connections for the external supply terminals 1 and 2 the communication loop terminals 3 and 4 are iso to prevent electrical interaction between them the sensor visible LEDs are latched on for approx 10 seconds the associated horn sounds A loop of can be made to sound by reversing the polarity of the supply When not used as a supplementary evacuation sys the external 24 VDC supply shall be treated as component of the main power supply system and fall under the requirements of the main supply system per NFPA 72 1 Terminal layout A maximum space of 1 inch from the outside edge the electrical box to the inside edge of the dry or ceiling tile is allowable 2 Mounting Terminals Function 3 and 4 are used for the communication circuit Supply Positive Supply Negative Comm Line In and Out Comm Line In and Out Base Interconnect the B501BH 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 recommended Guidelines wiring must be installed in compliance with the Electrical Code and the local codes having juris and must not be of such length or wire size which cause the base to operate outside of its published The conductors used to connect smoke sen to control panels and accessory devices should be coded to reduce the likelihood of wiring errors connections can prevent a system from respond properly in the event of a fire signal wiring the wiring between interconnected sen or modules it is recommended that the wire be no than 18 gauge 1.0 square mm Wire sizes up to gauge 2.5 square mm may be used with the base For system performance the power and wires and communication circuit wires should be twisted pair or cable installed in separate grounded conduit to the communication loop from electrical interfer wire connections by stripping about 3 of insulation the end of the wire Then slide the bare end of the under the clamping plate and tighten the clamping screw Do NOT loop the wire under the clamping See Figure 3 3 zone wiring of the sensor base should be checked the sensor heads are installed Check the wiring for and polarity in the base the individual sensor manual for the maximum sensor temperature B501BH ELECTRICAL BOX INCH SQUARE BOX Instructions External supply shown in normal standby configu in Figure 4 wiring diagram for a typical 2 wire intelligent system shown in Figure 4 the monitor module is supervising external supply Before testing notify the proper authorities that smoke sensor system is undergoing mainte and therefore will be temporarily out of Disable the system undergoing mainte to prevent unwanted alarms and bases must be tested after installation and as integral part of periodic maintenance Test the B501BH follows Reverse the polarity of the external 24VDC supply All bases on the loop should sound in approximate 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 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 nec to complete testing of each sensor within this 4 limit to prevent the horn from sounding 4 Wiring diagram Grouping has approved horn grouping for up to six B501BH base horn units When wired as a group any detector in group that has its LED latched on by the panel will other B501BH units in the group to sound Grouping accomplished by wiring the grouped devices together terminal 5 Sounder Base Interconnect as shown in diagram Since the grouping is not supervised the can only be used for supplementary signaling Grouping horns together can only be used as a sup evacuation system It is not acceptable to group for primary alarm signaling A OPTIONAL WIRING SOUNDER INTERCONNECT COMM COMM
