To provide an automatic reset operation method for a gas cut-off device improving safety when automatic reset operation at the occurrence of gas cut-off by a seismoscope sensor is based on detection not by an earthquake but by temporary impact.
Automatic reset operation at the occurrence of gas cut-off by the seismoscope sensor is started when receiving signals of vibration abnormality from a plurality of seismoscope sensors installed in adjacent areas, and if there is no abnormality of a flow measuring part, the seismoscope sensors and pressure sensors after opening a passage, reuse is permitted as it is, while when not receiving the signals, automatic reset operation is not started, and an informing part informs the outside to that effect.
