sensor must be installed in compliance with the control panel system manual The installation must meet the requirements of the Au Having Jurisdiction AHJ Sensors offer maximum performance when in compliance with the National Fire Protection Association NFPA NFPA 72 DESCRIPTION 2351B and 2351B IV are plug in type smoke sensors that combine a sensing chamber with addressable analog communications sensors transmit an analog representation of smoke density over a com line to a control panel Rotary dial switches are provided for set the sensor address See Figure 1 1 ROTARY ADDRESS SWITCHES 0 0 LEDs on the sensor are controlled by the panel to indicate sensor status output is provided for connection to an optional remote LED annunciator RA100Z Sensor panels offer different features sets across different models As a certain features of the photoelectric sensors may be available on some panels but not on others 2351B and 2351B IV support Advanced Pro and CLIP Classic Loop Interface Protocol mode The possible features if supported by the control panel are The sensor LEDs can operate in three ways off and blinking can be set to red green or amber This is controlled by the panel The remote output may be synchronized to the LED operation or con independent of the LEDs Devices are point addressable up to 159 addresses refer to the operation manual for the UL listed control panel for specific The photoelectric sensors require compatible addressable com to function properly Connect these sensors to listed compatible panels only Sensor recommends spacing sensors in compliance with NFPA 72 In air flow applications with smooth ceilings space sensors 30 feet apart m For specific information regarding sensor spacing placement and applications refer to NFPA 72 or the System Smoke Detector Applica Guide available from System Sensor Applications 2351B and 2351B IV are listed for use in ducts See Duct Detectors Applications Guide HVAG53 for details on pendant mount ap NOTE Intelligent photoelectric smoke sensors are also listed for use DNR W duct smoke detectors GUIDE wiring must be installed in compliance with the National Electrical Code local codes and any special requirements of the Authority Having Proper wire gauges should be used The installation wires should color coded to limit wiring mistakes and ease system troubleshooting Im connections will prevent a system from responding properly in the of a fire power from the communication line before installing sensors Wire the sensor base supplied separately as shown in the wiring See Figure 2 Set the desired address on the sensor address switches See Figure 1 Install the sensor into the sensor base Push the sensor into the base while it clockwise to secure it in place After all sensors have been installed apply power to the control panel and the communication line Test the sensor s as described in the TESTING section of this manual covers provide limited protection against airborne dust particles during Dust covers must be removed before the sensors can sense smoke sensors prior to heavy remodeling or construction 2 WIRING DIAGRAM Do not loop wire under 1 or 2 Break wire run to connections A OPTIONAL WIRING C0129 10 photoelectric smoke sensors include a tamper resistant capability prevents their removal from the base without the use of a tool Refer to base manual for details on making use of this capability testing notify the proper authorities that the system is undergoing and will temporarily be out of service Disable the system to unwanted alarms sensors must be tested after installation and periodically thereafter Test methods must satisfy the Authority Having Jurisdiction AHJ Sensors maximum performance when tested and maintained in compliance with 72 When used properly the canned smoke agent will cause the smoke detec to go into alarm Refer to the manufacturer published instructions for use of the canned smoke agent sensor can be tested in the following ways Functional Magnet Test P N M02 04 01 or M02 09 00 Hold the test magnet in the magnet test area as shown in Figure 3 This sensor can be functionally tested with a test magnet The test magnet simulates smoke in the sensing chamber testing the sensor and connections to the control panel The sensor should alarm the panel Two LEDs on the sensor are controlled by the panel to indicate sensor Coded signals transmitted from the panel can cause the LEDs to latch on or latch off Refer to the control panel technical documen for sensor LED status operation and expected delay to alarm Smoke Entry Sensitivity readings are available through the FACP Refer to the manufac published instructions for proper use Additionally canned aerosol simulated smoke canned smoke agent may used for smoke entry testing of the smoke detector Tested and ap aerosol smoke products are Fire Safety Climb 30S PURCHECK CENTURIAN SOLOA4 TRUTEST 2000 aerosol simulated smoke canned smoke agent formulas will vary manufacturer Misuse or overuse of these products may have long term effects on the smoke detector Consult the canned smoke agent manu published instructions for any further warnings or caution statements sensor that fails any of these tests may need to be cleaned as described CLEANING and retested testing is complete restore the system to normal operation and notify proper authorities that the system is back in operation removing the detector notify the proper authorities that the smoke system is undergoing maintenance and will be temporarily out of Disable the zone or system undergoing maintenance to prevent un alarms Remove the sensor to be cleaned from the system Remove the sensor cover by pressing firmly on each of the four removal that hold the cover in place See Figure 4 Vacuum the screen carefully without removing it If further cleaning is continue with Step 4 otherwise skip to Step 7 Remove the chamber cover screen assembly by pulling it straight out Use a vacuum cleaner or compressed air to remove dust and debris from sensing chamber Reinstall the chamber cover screen assembly by sliding the edge over the chamber Turn until it is firmly in place Replace the cover using the LEDs to align the cover and then gently push Test the detector as described in TESTING Reconnect disabled circuits Notify the proper authorities that the system is back on line NOTE REGARDING SMOKE DETECTOR GUARDS detectors are not to be used with detector guards unless the combina has been evaluated and found suitable for that purpose 3 FEATURES OF THE PHOTO DETECTOR Alignment
