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. installing sensors, please read the system wiring and installation man- thoroughly. This manual provides detailed information on sensor spac- placement, zoning, and special applications. Copies of these manuals are from Fire-Lite. DESCRIPTION H355, H355R, and H355HT are intelligent sensors that utilize a state- thermistor sensing circuit for fast response. These sensors are de- to provide open area protection with 50 foot spacing capability. For which must comply with FM3210, see note below. Model H355 is fixed temperature sensor with 135 F fixed temperature alarm. Model H355R a rate-of-rise temperature sensor with 135 F fixed temperature alarm. H355HT is a high temperature sensor with 190 F fixed temperature LEDs on each sensor light to provide a local, visible sensor indication. LED annunciator capability is available as an optional accessory (Part RA400Z). H355, H355R, and H355HT require compatible addressable com- to function properly. Connect these sensors to listed-compat- control panels only. Per FM3210 H355 and H355HT are classified as fixed temperature thermal detectors: thermal detector that responds when the operating element of the detector a specified temperature. The actual temperature surrounding the sens- element is often much greater than the rated temperature due to the ther- lag. H355R is classified as a rate-compensated thermal detector: A thermal that responds to a specified fixed temperature, regardless of the rate of rise. GUIDE wiring must be installed in compliance with the National Electrical Code, local codes and the Authority Having Jurisdiction. Proper wire should be used. The installation wires should be color coded to limit mistakes and ease system troubleshooting. Improper connections will a system from responding properly in the event of a fire. power from the communication line before installing sensors. Wire the sensor base (supplied separately) per the wiring diagram, Figure 1. 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. 1. WIRING DIAGRAM: DO NOT LOOP WIRE TERMINAL 1 OR 2.
