The SeaHawk LD310 single zone leak detection controller monitors up to 300 feet (91 meters) of sensing cable. It is compatible with RLE SC, SC-R, and SC-ZH leak detection sensing cables, as well as SD-Z and SD-Z1 spot detectors.
Make Sure You Have An Isolated Power Supply!
RLE leak detection controllers, including the LD310, require an isolated power supply. A power supply is not included with the LD310. Purchase RLE’s WA-DC-5-ST with the LD310.
If you are using the LD310 in an international location, purchase the PSWA-DC-5 power supply and any applicable blade attachments.
