Greengate VAC-DT-2000-R Vacancy Ceiling Sensor w/BAS and Daylight Sensor, Dual Technology (Passive Infrared and Ultrasonic), 32 kHz, 360 Degree, 2000 square feet, 10-30 VDC, Class 2.

The Dual Technology sensor.s combination of Ultrasonic and Passive Infrared technologies offers the most complete sensing equipment available today. This pairing helps eliminate false activations or deactivations for additional energy savings. The OAC-DT sensors are also equipped with MicroSet self-adjusting technology which provides an adaptive and airflow tolerant technology, making them ideal for spaces which have increased airflow due to higher occupant levels. MicroSet self-adjusting Dual Technology sensors drastically simplify and reduce a contractor.s installation and adjustment time period.
