The SeaHawk LD1000 single zone leak and water detection controller monitors up to 1,000 feet (305 meters) of sensing cable. It is compatible with all SeaHawk sensing cables and SeaHawk SD-Z and SD-Z1 spot detectors.
As a stand-alone leak detection controller, the LD1000 features an audible alarm and three LED indicators. It is ideal for small areas, facilities where the sensing cable or spot detector is exposed or leaks can be easily located, and areas where the audible/visible alarm can be easily noticed. Plus, all LD1000 units are Modbus enabled so you can integrate them via Modbus output into existing monitoring systems.
Make Sure You Have An Isolated Power Supply!
RLE leak detection controllers, including the LD1000, require an isolated power supply. A power supply is not included with the LD1000. Purchase an RLE power supply – PSWA-DC-24-ST or WA-AC-24-ST.
