Abstract

PURPOSE: To prevent the gas explosion from occuring by a method wherein a gas leakage sensor and a ventilation device are equipped near gas piping in each room in arranging gas heater and the like in each room and, when a gas leakage occurs, the gases of all the rooms are shut off and the ventilation devices of all the rooms are put in operation by means of a central controlling apparatus.
CONSTITUTION: The central controlling apparatus 4 as a master machine issues commands to respective slave machines 5 and the respective slave machines 5, upon receipt of the command from the master machine 4, issue command to drive respective room heaters 3. Each slave machine 5 sends information signals on the room heater 3 and on the gas leakage sensor 7 to the master machine 4. The transmission and reception between the master machine 4 and the slave machines 5 are successively repeated. When the gas leakage signal of the gas leakage sensor 7 is received by the master machine 4, the master machine 4 issues stop commands of the room heater 3 to the respective slave machines 5 and at the same time issues the shut-off command of an emergency shut-off valve 2 and operation commands of ventilation device 9 in order to ventilate each room. In such a manner as described above, the gas explosion can be prevented from occuring and the safety and reliability of gas appliances can be improved.
