The Leviton’s Self-Contained Passive Infrared Ceiling Occupancy Sensor is the cost-effective choice for commercial and institutional installations, where installation of the recessed ceiling unit is difficult, inconvenient or costly. Available in 120 V, 220 V and 277 V versions, the ODC0S-I is ideal for storage areas, small bathrooms, copy rooms, mop/sink closets or small spaces without wall switches. The Self-Contained Ceiling Sensor does not require an external control unit for power or switching the load ON and OFF.

The Cat. No. ODC0S-I uses passive infrared (PIR ) detection technology to monitor a room for occupancy through a segmented Fresnel lens. This specialized lens divides the field of view into sensor zones. When a person passes into or out of a sensor zone, the sensor detects motion and switches its lighting loads ON. The lights will remain ON as long as there is an occupant moving through the sensor zones.

A delayed-OFF time adjustment prevents the lights from switching OFF when the space is occupied. In order to keep the lights ON, a person must pass through a sensor zone at least once during the selected delayed-O FF time interval. The delayed-O FF time settings can be adjusted from 20 seconds (for test mode) to 15 minutes. When the sensor does not detect motion during the selected delayed-O FF time, the sensor will switch the lights OFF automatically after the time interval expires.
