This LD1500 is ideal for areas where sensing cable may not be visible, and is most commonly installed in data centers (under raised floors), museums, libraries, clean rooms, and telecommunication centers.

The LD1500 features:

  • Distance-read leak detection controller.
  • Monitors up to 1,500 feet (457 meters) of RLE sensing cable.
  • Compatible with all SeaHawk sensing cables and the SeaHawk SD-Z spot detector.
  • An easy to use web interface, accessible from any browser or mobile device.
  • Integration via protocol into a larger BMS or RLE LD2100 or LD5200 controller.

 

The LD1500 requires an isolated power supply. A power supply is not included with the LD1500.  Purchase either RLE power supply PSWA-DC-24 or RLE’s LD-ENC.
