This dual technology operates by detecting Doppler shifts in transmitted ultrasound and passive infrared heat fluctuations. You control the technology and settings with easy to manipulate DIP switches.

  • Ultrasonic sensing with a frequency of 40 KHz
  • SmartSet™ technology will automatically fit occupant usage patterns
  • Activate SmartSet with a DIP switch
  • Sensor shall utilize Zero Crossing circuitry to reduce stress on relay and therefore increase sensor life
  • Sensor will not protrude from wall more than 3/8” and will have a color coordinated matching lens
  • Sensor shall feature a walk-through mode, where lights turn off three minutes after the area is initially occupied if no motion is detected after the first 30 seconds, set by DIP switch
  • Sensor shall cover up to 1,000 sq. ft. for walking motion, with a field view of 180 degree
  • Each sensing technology shall have a LED indicator that remains active at all times in order to verify detection within the area to be controlled
