Ceiling Mount Occupancy Sensor, PIR, Line Voltage

Model: OAC-P-0500-MV, OAC-P-1500-MV, OAC-P-1500-DMV

The MicroSet Passive Infrared Line Voltage Occupancy Sensing Ceiling Sensor is a motion sensing lighting control that is used for energy savings and convenience.  The sensor is available in both single and dual load control.

The sensor is designed to detect motion from a heat-emitting source (such as a person entering a room) within its field-of-view and automatically switch lights ON. These sensors have multi-segmented lenses. For units to sense motion, the person must cross between two segments. The distance between segments increases the farther you are from the sensor, so motion has to be larger the farther you are from the unit. PIR sensors are considered line-of-sight sensors, meaning that the sensor must be able to have a direct line-of-sight to the person making the motion. The sensor includes self-adaptive technology that continuously self-adjusts sensitivity and time delay in real-time, maximizing the potential energy savings that are available in the particular application. The MicroSet Passive Infrared Line Voltage Ceiling Sensor has an ambient light level sensor. When enabled, the daylighting feature prevents lights from turning ON when the room is adequately illuminated by natural light.
