Abstract

PURPOSE:To prevent an accident of gas leakage, by using the only piping for a gas piping to gas equipment devices and providing a shut-off valve and gas pressure measuring unit to an inlet side of said gas piping. CONSTITUTION:Terminal control devices 2 receives a signal from a central control unit 1 to both control gas room heaters 4 in accordance with a command of the signal and return a signal of an operating state or the like of the gas room heater 4 to the central control unit 1. When a measured value of pressure by a pressure sensor 8 is normal, a shut-off valve 7 is closed to start a check of gas leakage. Pressure measured several seconds after fully closing is compared with pressure measured with the lapse of one minute after that, and its difference is checked to perform decision from whether the difference is within a permissible amount or not.
