The Leviton Smart Sensor with 1000W dimming can easily switch and dim incandescent and dimmable LED or CFL bulbs while monitoring a room for occupancy using Passive Infrared (PIR) detection technology. A specialized lens divides the field-of-view into sensor zones. When a person passes in or out of a sensor zone the sensor detects motion and switches the lights ON. The lights will remain ON as long as long as an occupant moves through the sensor zones and until the timeout expires. The ODP10-I1x features a vacancy mode for Manual-ON/Auto- OFF operation, ideal for installations where manual-ON switching is required for energy code applications.
