33 to 64 Zone Water Leak Detection Alarm Type LD64-2

Taking over from the LD32 system, this unit will provide water leak detection in up to 64 individual areas or sectors and will look for leaks from pipes, shower rooms, bathrooms, water softeners, air conditioning systems or any plant containing water. Each zone can be connected to either a length of water detection cable (rope) or a spot probe designed to detect leaks in bunbed areas or drip trays.

The alarm controller is fitted with a large touch screen display and communicates to remote water detection stations via an RS485 data link.

Configured as either 1, 2, 3 or 4 zones, a maximum of 32 detection stations, can be fitted to a system, between 1 and 300 metres away from the main alarm unit.

Local alarm, cable fault and test facilities are provided on each outstation so that the detection station alarm status is displayed without the need to interrogate the main alarm unit. Outstations can also be fitted with an additional PCB allowing individual zones to operate a water shutoff valve to stop the leak from causing further damage.
