Abstract
An elongated fluid detection cable is described for use in detecting the presence of fluid (e.g. water) in areas where fluid is not desired. The cable includes a non-conductive base and at least two conductive members (such as wires). The base is twisted about its longitudinal axis, and the two conductive members are protected from touching conductive surfaces. The cable is connected to a control system which will activate an alarm when fluid contacts the conductive members of the cable. In one system, the cable includes four conductive members.
