The water leak detector cable itself is the sensor. Every centimetre of rugged, fire rated cable is sensitive to water and when water comes into contact with the cable, even a few millilitres, the system is able to detect the leak AND report the location. The detection cable can be installed in any length from a few metres in a drip tray to hundreds of metres around the perimeter of an office area. Typical applications in office buildings include the monitoring of fan-coil units around the edge of the building office floors, detectors surrounding the central utility core on each floor of the building and dedicated monitoring of leaks in electrical switch gear rooms, server rooms, network communications, etc.
