SD355, SD355T and AD355 Addressable Photoelectric Smoke Sensors and Maintenance Instructions sensor must be installed in compliance with the control panel system installation manual. The installation must meet the requirements of the Authority Having (AHJ). Sensors offer maximum performance when installed in compliance with the National Fire Protection Association (NFPA); see NFPA 72. DESCRIPTION SD355, SD355T and AD355 are addressable sensors that combine a state-of-the-art photoelectronic sensing chamber with communications. The sen- transmit an analog representation of smoke density over a communication line to a control panel. Rotary decade switches are provided for setting the sen- address. LEDs on the sensor are controlled by the panel to indicate sensor status. An output is provided for connection to an optional remote LED annunciator (P/N Models AD355 and SD355T combine a photoelectronic sensing chamber and 135 (57.2 fixed temperature heat detector.

For specific informa- regarding sensor spacing, placement, and special applications, refer to NFPA 72 the System Smoke Detector Application Guide available from Fire INSTRUCTIONS wiring must be installed in compliance with the National Electrical Code, applicable local codes, and any requirements of the Authority Having Jurisdiction. Proper wire gauges should be used. The installation should be color-coded to limit wiring mistakes and ease system troubleshooting. Improper connections prevent 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, see Figure 1. Set the desired address on the sensor address switches, see Figure 2. Some panels support extended addressing. In order to set the sensor above address 99 on compat- systems, carefully remove the stop on the upper rotary switch with thumb or as shown in Figure 2. the sensor into the sensor base. Push the sensor into the base while turning it clockwise to secure it place. After all sensors have been installed, apply power to the control unit and activate 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 shipping. Dust must be removed before the sensors can sense smoke. Remove sensors prior to heavy or construction. SD355, SD355T and AD355 include a tamper-resistant capability that prevents its removal the bracket without the use of a tool. Refer to the base manual for details on making use of this testing, notify the proper authorities that the system is undergoing maintenance, and will tem- be out of service. Disable the system to prevent unwanted alarms. sensors must be tested after installation and periodically thereafter. Testing methods must satisfy Authority Having Jurisdiction (AHJ). Sensors offer maximum performance when tested and main- in compliance with NFPA 72. The sensor can be tested in the following ways: Functional: Magnet Test (P/N M02-04-01 or M02-09-00) sensor can be functionally tested with a test magnet. The test magnet electronically simulates in the sensing chamber, testing the sensor electronics and connections to the control panel. Hold the test magnet in the magnet test area as shown. The sensor should alarm the panel. LEDs on the sensor are controlled by the panel to indicate sensor status. Coded signals, from the panel, can
