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 add
