National Fire Alarm and Signaling Code and or 76 Standard for the Fire Protection of Telecommunications Facilities DESCRIPTION 7351 is a plug in type smoke sensor that combines a photoelectronic chamber with addressable analog communications providing sensi from 0.02 per foot to 2 per foot obscuration for Early Warning Fire EWFD or Very Early Warning Fire Detection VEWFD 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 Applications 7351 is listed for use in ducts See Duct Smoke Detectors Guide HVAG53 for details on pendant mount applications NOTE High sensitivity 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 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 7351 supports CLIP Classic Loop Interface protocol mode The possible features available in the photoelectric 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 2 WIRING DIAGRAM Do not loop wire under 1 or 2 Break wire run to connections A OPTIONAL WIRING High sensitivity Photoelectric smoke sensors include a tamper re capability that prevents their removal from the base without the use of tool Refer to the base manual for details on making use of this capability C0129 10 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 it until it locks into place Reinstall the detector 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 Notch 4 CLEANING THE PHOTO DETECTOR Test Marker C2021 00 Cover Chamber and Screen Chamber C2022 00 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 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 include Fire and Safety Climb 30S PURCHECK CENTURIAN SOLOA4 TRUTEST 2000 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 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 instructi
