Dual Technology Occupancy/Vacancy Sensor

WS-XX-DT-XX

The Dual Technology Occupancy/Vacancy Sensor applies exclusive XCT Technology to the ultrasonic as well as the passive infrared technology in this sensor to create a product that can detect very fine motion, such as typing. This product also includes: adaptive relay switching, smart ambient light detection, and simple button presses for changing settings. This switch is available in single-circuit and dual-circuit versions.

The single-circuit versions (WS XX DT) can be used to meet many of the Title 20/24, ASHRAE 90.1, and IECC code requirements such as “automatic shutoff”. The dual-circuit version (WS OS DTDR) can be used to meet many of the Title 20/24, ASHRAE 90.1, and IECC code requirements such as “automatic shutoff” and “multi-level lighting control”.
