Abstract

Improvements in security systems for the detection of low concentrations of combustible gases, which function to cut off a fuel supply by detecting the presence of a combustible gas, characterized by the fact that it includes remote controlled valve means in the main fuel supply to connect and disconnect said supply; at least one transducer positioned to carry out the detection of a combustible gas, the transducer of which has first and second elements; means for exciting the first element with short duration pulses from a voltage source; means for detecting a flow of current between the two mentioned elements upon detection of a gas, and means operable on the basis of the detected current flow to pass the valve to the closed position.
