An emergency gas line shut-off system for automatically preventing a flow of gas into a structure during the detection of emergency conditions. The emergency gas line shut-off system includes a gas valve for mounting on a gas supply line. The gas valve is electrically connected to a central control assembly for controlling the gas valve. The central control assembly preferably comprises control circuitry for determining when the gas valve should be in a closed condition for preventing the flow of gas into a structure. The control circuitry is mounted in a housing and is electrically connected to a detector for detecting a condition requiring the closed condition of the gas valve. The detector may comprise, for example, a smoke detector for detecting smoke, a carbon monoxide detector for detecting carbon monoxide or an earthquake detector for detecting earthquakes.
