overview

WattStopper’s low profile DT-355 dual technology occupancy sensor combines the benefits of passive infrared (PIR) and ultrasonic technologies. the sensor mounts on the ceiling with a flat, unobtrusive appearance and provides 360 degrees of coverage.
FEATURES
  • Architecturally appealing low profile appearance
  • Auto set automatically selects optimal settings for each space
  • Ultrasonic diffusers give more comprehensive coverage
  • Operates at 120, 230, 277 or 347 VAC, 50/60 Hz
  • Terminal wiring for quick and easy installation
  • Walk-through mode increases savings potential

General Info
Special Features: Built-in light level sensor
Color: The DT-355 is line voltage and operates at 120, 230, 277 or 347 VAC. The sensor turns lighting on when both PIR and ultrasonic technologies detect occupancy. PIR technology senses the difference between infrared energy from a human body in motion and the background space. Ultrasonic technology uses the Doppler Principle and high frequency (40KHz) ultrasound to sense motion within the space. Once lighting is on, detection by either technology holds lighting on. When no occupancy is detected for the length of the time delay, lighting turns off. The DT-355 can also be set so that only one technology is needed to trigger or both technologies are needed to hold lighting on.
Typical Applications: Classrooms, Open Office Spaces, Large Offices, Computer Rooms
