180° PIR Occupancy/Vacancy Motion Sensor Wall Switch 3-Way | 120V | Enerlites DWOS-3R

180° PIR Occupancy/Vacancy Motion Sensor Wall Switch | ENERLITES DWOS-3R The ENERLITES DWOS-3R is a 180° PIR occupancy/vacancy motion sensor wall switch designed for energy-efficient lighting control in single pole or 3-way applications. Using advanced passive infrared (PIR) technology, the DWOS-3R detects motion within a 1200 sq.ft. coverage area and automatically adjusts lighting based on occupancy or vacancy conditions. This versatile switch operates in two modes: Occupancy Mode: Lights turn ON automatically when motion is detected and turn OFF after the selected time delay. Vacancy Mode: Lights must be turned ON manually and turn OFF automatically after no motion is detected. The DWOS-3R includes a manual ON/OFF push button and an adjustable time delay from 15 seconds to 30 minutes. Its walk-through mode enhances energy savings by turning lights off shortly after brief occupancy. The LED indicator light confirms motion detection, and the zero-crossing function ensures safe sw
