Horn Output Delay Time 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 2 sounder base is used with System Sensor 200 sensor heads Refer to the appropriate manual for more 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 loop of horns can be made to sound by reversing the polar of the external supply when configured as in Figure 4 and When configured as in Figure 5 a loop of horns can also be to sound 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 maximum than 90 dBA measured in anechoic room at 10 feet 24 volts 85 dBA measured in UL reverberant room to 5.7 sec 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 2 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 refer to insert for the Limitations of Fire Alarm Systems LIMITED WARRANTY Sensor warrants its enclosed smoke detector base to be free from defects in mate and workmanship under normal use and service for a period of three years from date manufacture System Sensor makes no other express warranty for this smoke detector No agent representative dealer or employee of the Company has the authority to or alter the obligations or limitations of this Warranty The Company obligation this Warranty shall be limited to the repair or replacement of any part of the smoke base which is found to be defective in materials or workmanship under normal and service during the three year period commencing with the date of manufacture phoning System Sensor toll free number 800 SENSOR2 736 7672 for a Return number send defective units postage prepaid to System Sensor Returns RA 3825 Ohio Avenue St Charles IL 60174 Please include a describing the malfunction and suspected cause of failure The Company shall not obligated to repair or replace units which are found to be defective because of damage use modifications or alterations occurring after the date of manufacture no case shall the Company be liable for any consequential or incidental damages for of this or any other Warranty expressed or implied whatsoever even if the loss damage is caused by the Company negligence or fault Some states do not allow the or limitation of incidental or consequential damages so the above limitation exclusion may not apply to you This Warranty gives you specific legal rights and you also have other rights which vary from state to state System Sensor 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 Figure 4 and 5 wiring diagram for a typical 2 wire intelligent system is in Figure 4 and 5 the monitor module is supervising external supply and bases must be tested after installation and as integral part of periodic maintenance Test the B501BH 2 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 and 5 reverse the polarity the external 24VDC supply If configured as in Fig 5 turn on the Intelligent Relay Module All B501BH bases on the loop should sound in approximately 0.75 5.7 seconds Latch the sensor LED on from the control panel That B501BH 2 should sound in approximately 0.75 to seconds There is approximately a 0.75 to 5.7 second delay built the B501BH 2 before sounding This delay is present the control signal comes from the sensor or from external 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 0.75 seconds Therefore it is to complete testing of each sensor within this limit to prevent the horn from sounding 1 Terminal layout 2 Mounting 4 Wiring diagram Activates Sounder Base s Complies with UL268 has approved horn grouping for up to six B501BH 2 base horn units When wired as a group any detector in the that has its LED latched on by the panel will cause B501BH 2 units in the group to sound This type of is accomplished by wiring the grouped devices to using terminal 5 Sounder Base Interconnect as shown in diagram Since a local grouping of horns is not supervised the can only be used as a supplementary evacuation system is not acceptable to group horns for primary alarm signaling A OPTIONAL WIRING SOUNDER INTERCONNECT 2 1 B501BH 2 ELECTRICAL BOX INCH SQUARE BOX 3
