The Sensor Shall Detect Occupancy In The Control Area By Detecting Doppler Shifts In Transmitted Ultrasound and Passive Infrared Heat Changes.? Detection Verification Of Both Technologies Must Occur In Order to Activate Lighting Systems.? Upon Verification, Detection By Either Shall Hold Lighting On.

The DW-100 Dual Technology Wall Switch Sensor Combines The Benefits Of Passive Infrared (Pir) and Ultrasonic Technologies, and Can Turn Lights Off and On Based On Occupancy

The DW-311 Dual Technology Dimming Wall Switch Sensor Can Turn Lights Off and On Based On Occupancy and Allow The User to Increase or Decrease The Lighting Level. It Combines The Benefits Of Passive Infrared (Pir) and Ultrasonic Occupancy Detection Technologies and Works With 0-10 VDC Dimming Drivers and Ballasts to Control Lighting Loads Including Leds.
