PIR Sensors


Our range of PIR sensors, when linked to a solenoid valve, are designed to protect vulnerable toilet areas from leaks resulting in excessive water usage and potential flood damage and are designed for compliance with the requirements for BREEAM WAT 04.

​Our high-quality IP44 rated range includes an option for ceiling mounted, or recessed for a sleek design and discreet install.  All our sensors are designed for indoor use, are easy to install, and have easy-to-use simple programming.

IP44 Rated PIR Occupancy Switch

PIR switches, when installed in conjunction with a solenoid valve, can be used to control the water supply in washroom areas.  Our PIR sensor detects an infrared source (body heat) as it enters the room, once detected the sensor automatically triggers the solenoid valve to switch open, allowing normal water supply to resume.  If the PIR sensor no longer detects a presence for a preset time (adjustable from 3 seconds to 18 minutes) the solenoid valve automatically shuts off the water supply again, protecting areas from potentially costly leaks from damaged ball valves and taps, and flood damage from burst pipes.  It also protects areas at risk of deliberate acts of vandalism such as schools, municipal public toilets.

Key features of our Solenoid Valve and PIR combination:

Water Saving
Automatically shuts off water supply off automatically when room becomes unoccupied

Reduces the need to check unattended public spaces with water supplies such as washrooms

​Suitable For
All commercial and domestic needs such as office and factory washrooms, hotels, schools and public toilets, holiday rentals

Easy to Install
With only 3 wire connections required: Live, neutral & switched live

Flexible Installation for every need
Multiple PIR sensors can be wired in parallel to cover larger spaces; while a single PIR sensor can control multiple valves, or multiple PIRs can be wired in parallel to control a single solenoid valve
