Leviton’s new OSSMD Dual Relay Multi-Technology Wall Switch Occupancy Sensor line combines bi-level switching with infrared & ultrasonic technology for accurate occupancy detection. Minimal false triggering provides “install & forget” performance and maximum energy savings. A PIR-disable function offers flexibility in applications with extreme changes in airflow or temperature. The OSSMD-G does not require a neutral wire for installation, making it perfect for retrofit applications. The OSSMD-F is ideal in commercial restrooms where the second relay keeps the exhaust fan on for 10 min longer than occupancy to clean air. Lightfair booth No. 827
