Abstract

PURPOSE: To prevent the outflow of unburnt gas automatically by closing an electromagnetic valve in response to a malfunction signal within a time period preset in a timer in case that gas has failed to be ignited or flame is extinguished unexpectedly during use of the gas.
CONSTITUTION: In each gas appliance 5 connected to gas supply passage 1, there are provided a switch S1 operated with opening and closing of respective appliance cock 4, a flame-sensitive element S2 which closes an electric circuit when combustion flame exists, and a controlling unit 6. To the control unit 6, there are afforded a "cock open" signal indicating that the appliance cock 4 is opened, obtained from signals of the switch S1 and the flame-sensitive element S2, and a malfunction signal indicating that gas is not ignited when a predetermined time period is passed after opening of the cock 4, which is given via a delay circuit or a timer 13. Further, there is provided a centralized controlling panel 7 which functions to close a circuit for supplying current to an electromagnetic valve 8 in case that a "cock open" signal is given from either one of the controlling units 6 and to open the said circuit in case that a malfunction signal is given from either one section in the system.
