D500-40-00 1 I56-1436-00 1551B Plug-in Intelligent Ionization Sensors with Communications INSTALLATION AND MAINTENANCE INSTRUCTIONS A Division of Pittway 3825 Ohio Avenue, St. Charles, Illinois 60174 1-800-SENSOR2, FAX: 630-377-6495 Before Installing Please thoroughly read Guide for Proper Use of System Smoke Detectors (I56-407-XX), which provides detailed in- formation on sensor spacing, placement, zoning, and spe- cial applications. Copies of this manual are available from System Sensor. General Description Models 1551B dual-chamber ionization intelligent sensors utilize a state-of-the-art, unipolar sensing chamber. These sensors are designed for use with duct housings DH500 and DH500AC/DC only, and to be used with compatible control panels only. Connect sensors only to compatible control units. (For installation in Canada, refer to CAN/ ULC-S524-M86, Standard for the Installation of Fire Alarm Systems and CEC Part 1, Sec. 32.) Two LED’s on each sensor light to provide a local 360° vis- ibility of the sensor indication. The LED’s can be latched on by code command from the panel for an alarm indica- tion. The LED’s can also be unlatched to the normal condi- tion by code command. Remote LED annunciator capability is available as an optional accessory (Part No. RA400).

Therefore, connect all wiring following the installation instructions provided with the base that was selected for use with the 1551B. As Figure 1 indicates, bases are equipped with screw terminals for all appropriate connections. NOTE: All wiring must conform to applicable local codes, ordinances, and regulations. NOTE: Verify that all sensor bases are installed and that the wiring polarity is correct at each base. WARNING Remove power from the loop before installing sensors. 1. Install sensors: a. Verify that the sensor type matches the type written on the label on the base. b. Set the sensor to the desired address and record it on the label on the base. c. Place the sensor into the sensor base. d. Rotate the sensor clockwise until it drops into place. e. Continue rotating the sensor clockwise until it locks in place.
