Designed with  office refurbishment and home in mind, the LD1V water leak detection system detects water leaks that can occur at tea points and areas where hot drinks are prepared, as well as in kitchens areas, around vending machines and in a whole variety of small areas.

The LD1V alarm has been designed to mount into a standard electrical double socket back box. Being limited to and supplied with, 3 metres of interconnecting and 5 metres of water detection cable, the unit must be positioned locally to the source of any water leak and suites areas such as tea points, kitchens or vending machines.

The LD1V can also stop the leak by closing a water valve and is provided with a valve shutdown override facility allowing reinstatement of the water supply after a leak, whilst waiting for the detection cable to dry out.

As standard, the LD1V is provided with a normally open volt free contact for onward signalling to a BMS or existing alarm system.

All of the information below is available in our LD1V Water Leak Alarm PDF data sheet.
