Pass & Seymour DSW301W Wattstopper Dual-Technology Occupancy Sensor, Single-Relay, 120/277V, White
The Pass & Seymour DSW301W is a Wattstopper multi-way dual-technology occupancy sensor built for single-relay lighting control at 120/277V. Finished in white, this sensor combines passive infrared and ultrasonic detection to reliably control lighting in spaces where a single technology can fall short, and it is designed to coordinate with additional units in multi-way switched circuits. Selectable operating modes, an audible pre-shutoff alert, and a vandal-resistant lens make it a practical choice for commercial spaces that demand dependable, code-driven lighting control.
Key Features
- Dual-Technology Detection: Combines passive infrared and ultrasonic sensing for accurate occupancy detection across varied room conditions.
- Selectable Walk-Through Mode: Turns lights off three minutes after initial occupancy if no additional motion is detected within the first 30 seconds, reducing wasted energy in transient spaces.
- Automatic Mode Recovery: In automatic mode, the sensor returns to Auto-ON operation after lights are turned off manually, restoring hands-free control.
- Audible Shutoff Alert: Selectable audible alert warns occupants of an impending shutoff, ideal for presentations and meetings.
- Test Mode: Allows quick and easy adjustments during commissioning and troubleshooting.
- Four Occupancy Logic Options: Customizable control logic to match specific application requirements.
- Zero-Crossing Relay: Zero-crossing switching extends relay life for long-term reliability.
- Vandal-Resistant Lens: Durable lens design combines precise coverage with resistance to damage in high-traffic commercial areas.
- Single-Relay, Multi-Way Configuration: Rated for 120/277V single-relay operation and designed for multi-way switched lighting circuits.
- Finish: White housing with a matte finish for a clean, unobtrusive appearance on ceilings and walls.
