The Wattstopper W series Ultrasonic Ceiling Sensor is a versatile motion detector that controls lighting in a wide variety of applications. This sensor can be used individually or as part of an integrated system of Wattstopper lighting control products.  

The 24 VDC W series sensors utilize omni-directional, ultrasonic technology to sense occupancy. When movement is detected in a controlled area the sensor will switch lights on via low-voltage wiring through to a Wattstopper power or auxiliary pack. Once the area is vacated and the user-adjustable time delay (15 seconds to 15 minutes) has elapsed, lighting systems automatically switch off.

  • Turns lights on and off based on occupancy to reduce energy costs
  • Adjustable time delay from 15 seconds to 15 minutes
  • Automatic or manual-on operation when used with a BZ150 or BZ50 Power Pack
  • 1000 square feet coverage 
  • Ideal for open office areas, conference rooms and restrooms
  • Advanced Signal Processing (ASP) circuitry automatically adjusts detection threshold and eliminates false on
  • Omni-directional transmission provides 360° of coverage
  • LED indicates occupancy detection
  • Mounting Options: Ceiling tile, 4" square junction box
  • Light Output 1FCD: Automatic on/off
  • Load: 1 Amp @ 24VDC/VAC
  • Current: 16 mA
  • Voltage: 24 VDC
