Dual relay multi-tech wall box occupancy sensor w/neutral wire lighting control, 120/208/220/230/240/277v; 50/60Hz, CEC Title 20/24 Compliant, 30s-30m Time Delay, Ambient Light Override, Self Adjusting, Field Configurable, NAFTA Compliant. Color: White

Dual Relay Multi-Tech Wall Box Occupancy Sensor Lighting Control The Leviton OSSMD Dual Relay Decora® Wall Switch is a multi-technology occupancy sensor designed for commercial lighting control applications. It provides automatic lighting control for two separate lighting loads from a single device, suitable for incandescent, fluorescent, and low-voltage lighting as well as fan loads. This sensor integrates passive infrared (PIR) and ultrasonic (U/S) technologies to optimize occupancy detection and energy savings, making it an effective solution for electrical distributors and lighting solutions providers seeking advanced control devices. It is suitable for installation in a standard single-gang wall box and complies with California Title 20/24 energy efficiency standards.
