ABSTRACT:
An electric circuit for energizing a fire-suppressing foam generator includes a switch that is opened and closed by means operated by electric control circuits, one of which contains a pair of laterally spaced lower electric probe contacts mounted in the protected area and adapted to be bridged by a rising level of foam to close that circuit. The other control circuit contains a pair of laterally spaced upper electric probe contacts above the level of the lower contacts and adapted to be bridged by a rising level of foam to close the last-mentioned control circuit.
