WATTSTOPPER DSW-301-347-LA DUAL TECHNOLOGY WALL SWITCH OCCUPANCY SENSOR 347V LT. ALMOND

WATTSTOPPER DSW-301-347-LA Dual Technology Wall Switch Occupancy Sensor 347V Light Almond The WATTSTOPPER DSW-301-347-LA is a dual technology wall switch occupancy sensor designed for precise and reliable lighting control in commercial and institutional environments. Combining passive infrared (PIR) and ultrasonic sensing technologies, it effectively detects occupancy to automatically turn lighting loads ON and OFF. Ideal for retrofit projects and new installations, it supports multi-way control from up to four locations, making it suitable for offices, conference rooms, classrooms, and ADA-compliant buildings. This sensor is compatible with both 2-wire and 3-wire electrical connections and meets 2017 NEC requirements. Specifications Voltage: 347 VAC, 50/60 Hz Load Rating: 1500 W ballast, LED, 1/4 HP Time Delay Adjustment: 5 to 30 minutes (selectable) Walk-Through Mode: Turns lights OFF after 3 minutes if no motion detected after 30 seconds Test Mode: 10 minutes with 5-second time delay PIR Sensitivity: High or Low (50%) Ultrasonic Sensitivity: Adjustable from Minimum to Maximum or Off Ultrasonic Frequency: 40 kHz Light Level Adjustment: 8 fc to 180+ fc (optional) Audible Alerts: Selectable for impending shutoff Multi-Way Capability: Supports up to 4 sensors on the same circuit Terminal Screw Torque: 16 lbf-in (18 kgf-cm) Dimensions (LxWxD): 2.73” x 1.75” x 1.81” (69mm x 44mm x 46mm) Color: Light Almond Warranty: 5 years Features Combines PIR and ultrasonic technologies to reduce false triggers and enhance occupancy detection accuracy Selectable operating modes including Manual ON and Auto ON for flexible control Optional neutral wiring for compatibility with 2-wire and 3-wire applications Selectable walk-through mode reduces energy waste by turning lights off quickly after brief occupancy Test mode enables quick setup and adjustment Vandal-resistant lens with precise, dense coverage pattern Supports multi-way wiring for convenient control from multiple locations Audible alerts provide warnings before lights turn off Service mode allows sensor to function as a service switch in case of failure Complies with ADA mounting height requirements and 2017 NEC electrical codes Downloads & Links Spec Sheet Spec Sheet
