WATT STOPPER DSW302LA Wall switch occupancy sensor dual technology 2 relays 120/277V light almond

The DSW-302 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-302 replaces existing wall switches and fits a standard decorator wall plate. Complies with 2011 NEC requirements. Zero-crossing on both relays for long relay life. Vandal resistant lens combines precise coverage with durability. 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. Selectable audible alert for impending shutoff. In automatic mode, sensor returns automatically to Auto-ON after lights are turned off manually; ideal for presentations. Test mode allows quick and easy adjustments. Four occupancy logic options to customize control to meet application needs. Optional light level sensor holds secondary lights off when ambient lighting is above the preset level. Service mode allows sensor to operate as a service switch in the unlikely event of a failure. Sensor coverage tested to NEMA Guide Publication WD 7-2000.
