LD1000

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.  The LD1000 can also integrate into existing monitoring systems.  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.

Note: The LD1000 requires an isolated power supply. A power supply is not included with the LD1000.  Purchase either RLE power supply PSWA-DC-24 or WA-AC-24.
