The OSSMD line of dual relay multi-technology Decora style wall switch occupancy sensors features several models to provide automatic lighting control for energy savings and convenience in a variety of commercial applications. OSSMD combines multi-technology with all-digital architecture in a dual relay switch occupancy sensor to minimize false triggering. The OSSMD automatically analyzes room conditions and adapts to changing environments. The result is a code compliant, trouble-free, "install-and-forget" solution for bi-level switching and lighting control. Dual-relay, multi-technology wall switch sensor, 2400 sq. ft. major motion coverage, 400 sq. ft. minor motion coverage, commercial grade, California Title 24 compliant. Wall Plate not included with Occupancy Sensors. PIR and US technology for performance and sensitivity Controls two separate lighting loads from a single unit Manual-ON only for the secondary relay Features self-adjusting occupancy sensor technology with automatic "walk-through" sensing PIR can be disabled
