The OSWWV-IOW is a low voltage infrared occupancy sensor that works with the OSPxx series power pack to automatically control lighting. By sensing moving infrared heat sources (people, forklifts or other heat-emitting objects), the sensor automatically turns the lights ON during occupancy, maintains lights ON and, after a time delay, turns the lights OFF when the space is vacated. The sensor uses a wide view (110 deg) lens which detects large body motions over 50 ft. Away. Smaller motions such as hand movement can be detected up to 34 ft. An internal photocell allows the user to set the daylight override level. The mounting base, provided with the sensor, allows quick and easy mounting in corners, on walls or on ceilings using the twist-and-lock feature. The OSWWV-IOW mounts quickly to a wall or the ceiling using a supplied bracket. The sensor features excellent range and sensitivity to motion. Self-adjusting, circuitry makes the sensor install and forget.
