Having Jurisdiction AHJ Sensors offer maximum performance when in compliance with the National Fire Protection Association NFPA NFPA 72 DescriPtion SD355 SD355T and AD355 are addressable sensors that combine a photoelectronic sensing chamber with communications The transmit an analog representation of smoke density over a communi line to a control panel Rotary decade switches are provided for setting sensor address LEDs on the sensor are controlled by the panel to indicate sensor status output is provided for connection to an optional remote LED annunciator RA400Z Models AD355 and SD355T combine a photoelectronic sens chamber and 135 57.2 fixed temperature heat detector recommends spacing sensors in compliance with NFPA 72 In low flow applications with smooth ceilings space sensors 30 feet apart For information regarding sensor spacing placement and special appli refer to NFPA 72 or the System Smoke Detector Application Guide from Fire Lite instructions 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 see 1 Set the desired address on the sensor address switches see Figure 2 Install the sensor into the sensor base Push the sensor into the base turning it clockwise to secure it in place After all sensors have been installed apply power to the control unit 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 1

that its removal from the bracket without the use of a tool Refer to the 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 The sensor can be tested in the following ways Functional Magnet Test P N M02 04 01 or M02 09 00 This sensor can be functionally tested with a test magnet The test mag electronically simulates smoke in the sensing chamber testing the electronics and connections to the control panel Hold the test magnet in the magnet test area as shown 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 blink latch on or latch off Refer to the control panel technical docu for sensor LED operation and expected delay to alarm 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 the LEDs to align the cover and then gently it until it locks into place Make sure that the thermistors do not bent under the cover on SD355T and AD355 models Reinstall the detector Test the detector as described in TESTING Reconnect disabled circuits 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 Notify the proper authorities that the system is back on line 4 Smoke Entry Aerosol Generator Gemini 501 The GEMINI model 501 aerosol generator can be used for smoke entry Set the generator to represent 4 ft to 5 ft obscuration as de in the GEMINI 501 manual Using the bowl shaped applicator aerosol until the panel alarms Additionally canned aerosol simu smoke canned smoke agent may be used for smoke entry testing the smoke detector Tested and approved aerosol smoke products are Smoke Detector Tester model 25S available from Home Safeguard In and Chekkit Smoke Detector Tester models CHEK02 and CHEK06 from SDi When used properly the canned smoke agent will the smoke detector to go into alarm Refer to the manufacturer instructions for proper 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 adverse on the smoke detector Consult the canned smoke agent manufacturer instructions for any further warnings or caution statements For AD355 smoke entry testing should be performed immediately fol the magnet test Magnet test initiates an approximately 10 minute when the detector signal processing software routines are not Failure to first perform the magnet test will introduce a time delay the detector alarms Direct Heat Method Hair dryer of 1000 1500 watts SD355T and only A hair dryer of 1000 1500 watts should be used to test the thermistors the heat toward either of the two thermistors holding the heat approximately 12 inches from the detector in order to avoid dam the plastic housing The detector will reset only after it has suf time to cool Make sure both thermistors are tested individually sensor that fails any of these tests should be cleaned as described under and retested If the sensor fails after cleaning it must be replaced returned for repair testing is complete restore the system to normal operation and notify proper authorities that the system is back in operation 3 TEST MAGNET THERMISTORS AND AD355 STATUS TEST MAGNET AND refer to insert for the
