The OSWWV-RIW is a low-voltage infrared occupancy sensor that works with the OSPxx Series power pack, or other Class 2 power supplies, to automatically control lighting. By sensing moving infrared heat sources, 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 degrees) lens which detects large body motions over 50 feet away. Smaller motions such as hand movement can be detected up to 34 feet. Additionally, the sensor is designed with an isolated relay contact, enabling the sensor to interface with other systems (example: BAS, HVAC, or any drycontact capable device or system). 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.
