Abstract
A leak alarm system monitors the wetness of a floor. The alarm system comprises a housing having a flat bottom surface and support feet for supporting the housing off the floor such that each one of the support feet is in contact with the floor. Each support foot comprises an electrode of the alarm system. A low resistance condition between two electrodes of opposite polarity, such as occurs in the presence of a water leak, activates the alarm.
