Dual relay multi-tech wall box occupancy sensor lighting control The Leviton OSSMD is a dual relay multi-technology occupancy sensor designed for automatic lighting control in commercial applications. It integrates passive infrared (PIR) and ultrasonic sensing technologies to detect occupancy and control two separate lighting loads from a single-gang wall box. Suitable for a variety of lighting solutions, this sensor supports incandescent, fluorescent, low-voltage lighting, and fan loads, making it ideal for electrical distributors, lighting solutions providers, wire and cable installers, and switchgear suppliers.
