Wall Mount Occupancy Sensor, PIR, Low Voltage

Model: OAWC-P

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. In Automatic On Mode, the lights turn ON when a person enters the room. In Manual On Mode, the lights are turned ON by activating a  momentary switch (model # GMDS-*) that is connected to the sensor. When used with 2 level lighting (-R model only), Bi-level Automatic On can be achieved which allows Zone 1 to  come on automatically upon occupancy.  Zone 2 does not come on unless the occupant presses the optional momentary switch. When enabled, the daylighting feature (-R models only)  prevents lights from turning ON when the room is adequately illuminated by natural light.
