The DT WLS 2 is a line voltage, two relay, Dual Technology (PIR & ultrasonic) wall switch occupancy sensor intended to control bi-level 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 pier to pier grouping achieving expanded detection zones and multiway switching.


  • PIR & 40 kHz ultrasonic wall switch occupancy sensor
  • Trigger mode settings enable what sensing technologies are used to initially turn the load ON and what technologies are used to keep the load ON
  • Adjustable ultrasonic reach setting from 25% to 100%
  • Line voltage lighting control (120/230/277 VAC, 50/60 Hz)
  • 180° coverage pattern
  • Manual ON or Automatic ON option
  • Light level feature keeps lights off when sufficient daylight is present
  • Mounts to a single-gang NEMA-style, standard switch box & decorator-style wall plate by others
  • “Switch Link” communication allows for up to 4 sensors to be grouped together
