Steinel Dual Tech Wall Switch Occupancy Sensor | DT WLS 1 #66220

The DT WLS 1 is a line voltage, single relay, Dual Technology (PIR & ultrasonic) wall switch occupancy sensor intended to control lighting in commercial spaces. The combination of both technologies enhances occupancy detection in difficult applications. DIP switch adjustable technology options to initiate the load ON and maintain the load ON with either or both technologies. 

 The hold off photocell daylight option will keep the lighting load OFF when the light level is greater than the threshold level setting. The convenient “Switch Link” feature enables up to four sensors to link together for peer to peer grouping achieving expanded detection zones and multiway switching. 

Applications: The typical application is for small offices, conference rooms and break rooms. For best performance use this sensor in enclosed spaces no larger than 20’ x 16’.
