Reshaping Duct Smoke DetectionThe System Sensor line of duct smoke detectors offers testing and inspection features to meet any code. With an intuitive designand simplified feature set, the DUCTSD duct detector is ideal for many standard applications. For complex applications, the 2:1 sensor-to-power capability of the D4120 duct detector allows a single power board to monitor sensors installed in both the supply and return. The easily accessible Smoke Test Port (on DUCTSD model only) and Test/Reset button (included on DUCTSD and D4120) simplifies testing for conventional 4-wire models. Plus, the flexible housing overcomes mounting constraints by adjusting to fit a broad range of applications. System Sensor provides increased flexibility with a variety of accessories, including two remote test stations and several different means of visible and audible system annunciation. All duct smoke detectors and accessories are UL listed.
