We’re pleased to announce that our PIR Water Isolation Kits are now available online, providing a simple and effective solution for reducing water waste, lowering utility costs and helping to protect buildings from leaks and water damage.
Designed to automatically shut off the water supply when an area becomes unoccupied, the kit features either a recessed PIR sensor or a surface-mounted ceiling movement detection sensor, together with a motorised ball valve junction box and a WRAS-approved motorised shut-off valve.
It’s an ideal solution for commercial buildings, schools, colleges and universities, manufacturing facilities, and hospitality and leisure environments. PIR-controlled automatic water isolation helps reduce the risk of hidden leaks, flooding and costly water damage; and can potentially deliver a cost-saving of up to 75%, depending on the application and existing usage.
The kit includes:
5727- Recessed PIR Sensor, Ceiling Mount Flush
5726 – Ceiling Mount Surface PIR Sensor
MBV-JB/230V – Motorised Ball Valve Junction Box 230VAC
LL-MBV-15/230V – Motorised Ball Valve 15mm
LL-MBV-22/230V – Motorised Ball Valve 22mm
You can select from a Recessed PIR Sensor, Ceiling Mount Flush PIR Sensor, or Ceiling Mount Surface PIR Sensor, depending on your project requirements. The Ceiling Mount Surface PIR Sensor offers a compact, discreet design with reliable motion detection, making it particularly suitable for smaller rooms and similar spaces.
The Recessed and Ceiling Mount Flush PIR Sensors are designed for installation within suspended ceilings or soffits and provide 360° coverage with a detection diameter of up to 8 metres. Where required, the detection area can be further tailored using shrouds.
The kit is fully configurable and can be supplied with the required number of Valve Junction Boxes, together with a choice of 15mm or 22mm motorised ball valves. Quantities can be adjusted to suit the specific requirements of each project.
When integrated, the PIR sensor, Valve Junction Box(es), and motorised ball valve(s) create a fully automatic water isolation system.
