The Wattstopper DW-100-24-W is a dual technology low voltage wall switch occupancy sensor operating at 24V, finished in white, suited for commercial spaces utilizing low-voltage switching systems such as offices, classrooms, and conference rooms. It combines passive infrared (PIR) and ultrasonic detection to minimize false-off events, requiring both technologies to confirm vacancy before switching off loads. The standard decorator-style form factor installs in a single-gang box for straightforward integration into existing low-voltage control systems.
