WattStopper.s WT Ultrasonic Ceiling Sensors utilize 32 KHz frequency ultrasonic technology to detect occupancy. The sensors are available in several models to control lighting in a wide variety of applications. ASP circuitry helps to eliminate false on. Advanced, omni-directional, ultrasonic technology for reliable occupancy detection. Angled transmitter and receiver pairs help optimize sensitivity while eliminating unwanted detection from ceiling air movement. Coverage ranges from 600 to 2200 square feet, and 90 linear feet for hallways. Isolated relay can interface with HVAC, EMS or an additional lighting load. DIP switch-adjustable time delay and sensitivity. LED indicates occupancy detection. Qualifies for ARRA-funded public works projects.
