The Wattstopper DT-355 is a low-profile dual technology ceiling occupancy sensor rated for 100–347V with a 360° center-mount coverage pattern, designed for open offices, conference rooms, and other commercial spaces requiring reliable occupancy detection. Combining passive infrared (PIR) and ultrasonic technologies, it reduces false-off events by requiring both detection methods to confirm vacancy. The wide voltage range supports use across North American commercial and industrial electrical systems.
