DUALTECH WALLSWI OCCSNS 2RLY 120/277 BLK

The DSW-200 dual technology wall switch sensor turns lights ON and OFF based on occupancy and contains two relays for controlling two independent lighting loads or circuits. It combines the benefits of passive infrared (PIR) and ultrasonic detection technologies for high sensitivity to small and large movements. The DSW-200 replaces existing wall switches and fits a standard decorator wall plate. Complies with 2011 NEC requirements. Detection Signature Processing eliminates false triggers and provides immunity to RFI and EMI. Zero-crossing on both relays for long relay life. Vandal resistant lens combines precise coverage with durability. Choice of Manual-ON or Auto-ON operation, selectable for each relay. Selectable walk-through mode turns lights off three minutes after the room is initially occupied if no motion is detected after the first 30 seconds. Test mode allows quick and easy adjustments.
