The detector is capable of performing comprehensive self-diagnostics and storing the results. Duct units installed in the supply air side may monitor upstream equipment and/or filters. Fortunately, it's easy to cover a smoke detector and prevent it from going off at an inopportune time. The DSD Series, 4-wire photoelectric duct smoke detector features a pivoting housing that fits both square and rectangular footprints and mounts to round or rectangular ductwork.
