SP/3WAY VACANCY WALL SENSOR

SP/3WAY VACANCY WALL SENSOR – Product Description

🔌 What it is

A single-pole / 3-way vacancy wall sensor switch is a wall-mounted lighting control device that uses motion detection to automatically turn lights OFF when a room is unoccupied, while requiring a manual ON action.

It can also be used in a 3-way switch setup, allowing control from two locations (like hallway + room entry).

🧾 What the name means

• SP → Single-pole (controls lighting from one location)
• 3WAY → Compatible with a 3-way circuit (two control points)
• VACANCY → Manual ON, automatic OFF (lights do NOT turn on automatically)

⚡ What it does

This device:

• Requires user to turn lights ON manually
• Uses a motion sensor (typically PIR) to detect occupancy
• Automatically turns lights OFF after a preset time with no movement
• Helps reduce energy waste from lights left on

In a 3-way configuration, one location is typically the sensor, and the other is a companion or standard switch depending on wiring design.

🏠 Typical uses

• Bathrooms
• Closets
• Garages
• Laundry rooms
• Utility rooms
• Hallways (depending on code requirements)
• Energy-code compliant residential builds (Title 24 / ASHRAE-style requirements)

🧠 Simple explanation

This is a wall switch that you turn on manually, and it automatically shuts the lights off when no one is in the room—even if you forget. It can also work with a second switch location.
