B501 Base oz 147 g listed for Duct Applications 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 2351BR and 2351BR IV are plug in type smoke sensors that combines photoelectronic sensing chamber with addressable analog communications used in duct applications with a DNR W testing can be done remotely approved System Sen sor test accessories eliminating the need for a test The sensors transmit an analog representation of smoke density over a line to a control panel Rotary dial switches are provided for the sensor address 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 Only System Sensor approved accessories may be used with the 2351BR 2351BR IV 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 2351BR and 2351BR IV support Advanced and CLIP Classic Loop Interface Protocol mode The possible fea available 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 2351BR and 2351BR IV 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 2351BR and 2351BR IV are listed for use in ducts See Duct Detectors Applications Guide HVAG53 for details on pendant mount NOTE 2351BR and 2351BR IV are also listed for use inside 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 per the wiring diagram 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 2351BR and 2351BR IV include a tamper resistant capability that pre their removal from the base without the use of a tool Refer to the base 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 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 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 by Misuse or overuse of these products may have long term ad effects on the smoke detector Consult the canned smoke agent manufac published instructions for any further warnings or caution statements Remote Test 2351BR and 2351BR IV can be remotely tested using the RTS151 or test accessories Refer to the DNR W manual for wiring dia Maximum test response time may be up to two communications the panel sensor that fails any of these tests may need to be cleaned as described CLEANING and retested When testing is complete restore the system normal operation and notify the proper authorities that the system is back 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 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
