Leviton® 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, 220 and 277 VAC 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. LED ready.
