OAC-DT-0501 MicroSet Ceiling Sensor, Dual Technology (Passive Infrared and Ultrasonic), 40 kHz, 180 Degree, 500 Square Feet, 10-30 VDC, Class 2

The Controls 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 Micro Set 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. Micro Set self-adjusting Dual Technology sensors drastically simplify and reduce a contractor's installation and adjustment time period. Dual Relay control. The Micro Set self-adjusting technology continuously monitors multiple sub-frequencies in the event that if a continuous Doppler shift occurs, such as those created by airflow from an air duct, the sensor will identify the noise as continuous and then block it out of view at a select sub-frequency. It will continue to monitor other sub- frequencies for human motion. This avoids false-activation, while still maintaining the high level of sensitivity that is necessary for sensing minor motion in a changing environment. Separate concurrent time delays for both Passive Infrared and Ultrasonic technologies avoid false activations or deactivations. In Automatic On Mode, the lights turn ON when a person enters the room. In Manual On Mode (-R model only), the lights are turned ON by activating a momentary switch (model # GMDS) that is connected to the sensor. When enabled, the daylighting feature (-R models only) prevents lights from turning ON when the room is adequately illuminated by natural light. Applications - classrooms, conference rooms, office spaces, common areas, computer rooms, break rooms, hallways, other indoor office spaces.
