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

Wattstopper® Multi-Way Dual Technology Occupancy Sensor, Single-Relay, 120/277V, Black – Occupancy Sensor Lighting Solutions The Wattstopper® DSW-301 is a dual technology multi-way wall switch occupancy sensor designed to control lighting loads based on occupancy detection. Combining passive infrared (PIR) and ultrasonic detection technologies, it effectively reduces false triggers in complex environments. This sensor replaces standard wall switches and fits behind decorator-style wall plates, making it suitable for electrical distributors and lighting solutions providers managing wire and cable or switchgear supply for commercial and institutional applications. Specifications Voltage: 120/277 VAC, 50/60 Hz Load Capacity: 1000W Number of Poles: Multi-Location Dimensions: 2.73 inches (Height) x 1.76 inches (Width) x 1.83 inches (Depth) Operating Modes: Manual ON or Auto ON selectable via DIP switches Detection Technologies: Passive Infrared (PIR) and Ultrasonic Light Level Adjustment: Sensor includes light level sensor to hold load off when adequate daylight is present Multi-Way Capability: Supports up to 4 sensors on the same circuit for coordinated control Terminal Screw Torque: 16 lbf-in (18 kgf-cm) Country of Origin: China Manufacturer: Pass & Seymour Manufacturer Part Number: DSW301B Features Dual technology sensing combining PIR and ultrasonic for reliable occupancy detection Single relay with ON/OFF button for manual override and control Selectable operating modes allow load to be turned ON and held ON as long as occupancy is detected by either or both technologies Walk-through mode turns lights off after 3 minutes if no activity is detected following occupancy Light level sensor prevents lights from turning on when sufficient daylight is present Compatible with standard decorator wall plates for easy retrofit installation Supports multi-location wiring for convenient control of common loads from multiple sensors Adjustable PIR sensitivity and ultrasonic detection levels to optimize performance and minimize false triggers Includes masking tape to block unwanted PIR sensor coverage areas Test mode with reduced time delay to facilitate commissioning and adjustment Optional neutral wiring available for applications requiring neutral connection Downloads & Links Cleaning Instructions for Wiring Devices DSW-301-347/302-347 Dual Technology Wall Switch Occupancy Sensors (TriLingual) DSW-301 Dual Technology Wall Switch Occupancy Sensor DSW-301/302 Dual Technology Wall Switch Occupancy Sensors (TriLingual) Spec Sheet
