Watt Stopper UW-100 Ultrasonic Wall Switch Sensor

Ultrasonic Technology Switches Lights ON Even When Occupants Are Not in Clear Line of Sight


Qty:  

What's special about this ultrasonic switch?

  • Lights are switched on or off depending on the occupancy of the room, which means no more wasted money from lights left on all day.
  • Able to sense ambient lighting, that therefore your lights will not switch on SIMPLY because you entered the room, rather because you entered and need the lighting.
  • Utilizes high frequency ultrasound and Doppler Principle to detect occupancy and adjust lighting.
  • Highly sensitive to any movement in the area, whether large or small.
  • Attractive design is aesthetically appealing

    SmartSet technology is what allows the UW-100 to constantly monitor the room to detect patterns of usage, and automatically adjust the time delay for maximum energy efficiency. Your switch will assign short shut off time delays (as little as seven minutes) for times when the room is usually empty, and longer delays (up to 30 minutes) when there is more traffic. Incredibly accurate and intuitive device can sense the difference between electrical noise and human motion for greater performance.

    Your sensor switch will work with fluorescent and incandescent lighting loads, and is compatible with energy-efficient electronic ballasts. Since the sensors use ultrasonic sound waves to detect motion, there is no need to have a clear line of sight.

     

    Applications:

  • Perfect for use in areas where the sensor may have a partially obstructed line of sight from the people who may enter the room.
  • Excellent for restrooms, restrooms with two stalls and utility/storage rooms.
  • DO NOT use ultrasonic wall switch sensors:
  • In areas where the doors will remain open
  • In areas with excessive air flow
  • For emergency or exit lighting
  • Within six feet of an air duct
