The WLDS-10 & WLDS-20 mk2 water leak detection panels monitor the flow of water into a building and sound an alarm and optionally shut off the supply should the flow rate exceed preset parameters.
It activates when the flow exceeds the pre-set maximum for the pre-set period of time and can identify different flow and therefore leakage rates, in accordance with BREEAM Wat 3. These parameters can be adjusted by the user to allow for different conditions.
IMPORTANT: in order that meaningful parameters are entered, a full water audit should be carried out in order to establish water consumption trends over a period of time.
WLDS-10 & WLDS-20 Mk2 WATER LEAK DETECTION SYSTEMS
Designed to detect major leaks and help prevent flood damage caused by leaking pipes and fittings or by vandalism.
The WLDS-10 Mk2 water leak detection panel is connected to a pulse water meter installed at the site boundary or main intake point of the building and hence monitors the consumption of water. An audible/visual alarm output is activated when a continuous flow of water passes through the water meter at a flow rate above a preset maximum for a preset period of time.
A normally open free contact is provided for connection to a BMS (Building Management System) or to activate a local sounder/beacon type alarm.
A normally closed free contact is also provided to shut off the water supply via a solenoid shut off valve if required.
The WLDS-20 Mk2 is for installations where a pulse water meter is installed at the site boundary and at the main intake point of the building and in addition can detect a loss of water between the site boundary and the main intake point.
