Pass & Seymour WS301I Wattstopper PIR Occupancy Sensor, 800W/1200W, Ivory

Pass & Seymour WS301I Wattstopper PIR Occupancy Sensor, 800W/1200W, Ivory

The Pass & Seymour WS301I is a Wattstopper PIR single pole, single relay occupancy sensor designed to automate lighting control in commercial and residential spaces. Rated 800W at 120V and 1200W at 277V, this Ivory-finish sensor detects motion via passive infrared technology and switches connected lighting loads automatically, reducing energy waste in spaces with intermittent occupancy. Adjustable time delay and sensitivity settings let installers tune performance to the specific room, while a light level sensor holds lights off when ambient daylight is already sufficient.

Key Features

• Occupancy Detection: PIR (Passive Infrared) single pole, single relay sensor for automatic lighting control.
• Load Rating: Rated 800W at 120V and 1200W at 277V for reliable switching of lighting loads.
• Adjustable Settings: Adjustable time delay and sensitivity allow the sensor to be tuned to actual room occupancy patterns.
• Zero Crossing Circuitry: Reduces stress on the relay, resulting in increased sensor life.
• Light Level Sensor: Holds lights off when ambient lighting is above the preset level, helping reduce unnecessary energy use.
• Voltage Drop Protection: Patented voltage drop protection circuitry supports consistent, reliable operation.
• Two-Tier Fresnel Lens: Custom two-tier Fresnel lens enhances detection at the desktop level.
• Finish: Ivory color with a Matte finish for a clean, low-profile appearance.
