Wattstopper® Multi-Way Dual Technology Occupancy Sensor Dual-Relay, 120/277V, Black

Wattstopper® Multi-Way Dual Technology Occupancy Sensor Dual-Relay, 120/277V, Black The Wattstopper DSW-302 is a dual technology wall switch occupancy sensor designed for precise lighting control in commercial and office environments. It combines passive infrared (PIR) and ultrasonic detection technologies to sense both small and large movements, enabling automatic ON/OFF switching of lighting based on occupancy. Featuring two relays, it controls two independent lighting loads or circuits, supporting bi-level switching and multi-way control from up to four locations. This sensor is suitable for retrofit projects and ADA-compliant buildings, providing energy-saving solutions through advanced occupancy detection and flexible control options.
