A device and method for shutting off the flow of gas to a structure, such as a residence, when a fire is detected in the structure. The device has a fire detector for providing a status signal to indicate the presence of fire in a structure, an actuator in communication with the fire detector, and a shut-off valve located on a gas line and connected to the actuator. When the status signal is received by the actuator, the actuator causes the valve to close, thereby shutting off the flow of gas to the structure. The device also includes one or more of the following: a secondary electric power source, disturbance prevention circuitry, a shut-off valve position indicator, a manually operated means of closing the shut-off valve, and an alarm indicator for indicating the presence of fire in the structure. The method involves detecting a fire and providing a status signal to an actuator. Then the actuator moves the shut-off valve from an open position to a closed position. The method also involves providing an indication of the shut-off valve position.
