Three-pack PIR motion sensor switches

This Emerson three-pack adds automatic motion-activated control to existing lights. Each unit uses a passive infrared sensor that detects movement up to five metres within a 120-degree cone. The switches operate on 85-265 V AC and handle loads up to 40 W, making them suitable for LED, energy-saving and standard bulb fixtures. They mount on walls or ceilings with a 20 mm cut-out.

Built-in photocell and fixed 30-second timer

A daylight sensor prevents the switches from triggering in bright conditions, so lights only activate when ambient light is low. Once motion is detected, the load stays on for a fixed 30-second delay after the last movement. No wiring to a separate controller is required; each switch connects directly in-line with the light circuit for plug-and-play installation.

Ideal for hands-free lighting in hallways.

The three-pack suits homeowners wanting multiple entry points automated without rewiring. Renters or installers needing adjustable time delays, app control or occupancy sensing should look at other solutions, as these units offer only a fixed 30-second delay and no wireless connectivity.

Questions about this item

Will the PIR sensor itself need replacement after a certain period?

The Emerson PIR motion sensor switch contains no user-serviceable parts and has no embedded battery, so the unit is designed to operate without scheduled sensor replacement.

What limits how long the connected light can stay on continuously?

The built-in time delay is fixed at 30 seconds; the light will turn off 30 seconds after the last detected movement, and this delay cannot be adjusted.

How much heat does each switch generate when it runs all day?

Each switch draws a static current of 50 A and supports up to 40 W load power, so heat output will depend on the connected lighting load rather than the sensor itself.
