Ceiling Mount Vacancy Sensor, Dual Tech, Low Voltage

The MicroSet Dual Technology Low Voltage Vacancy Ceiling Sensor increases energy savings by requiring a Manual On input to turn ON the lighting.

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 deactivations for additional energy savings. The MicroSet 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. The lights are turned ON by activating a  momentary switch (model # GMDS-*) that is connected to the sensor. When enabled, the Daylighting feature prevents lights from turning ON when the room is adequately illuminated by natural light.
