1. A gas shut-off system for a building comprising:
one or more sensors located within the building;
one or more light indicators in operative communication with the one or more sensors; and
one or more gas shut-off valves in operative communication with the one or more sensors, each of the one or more gas shut-off valves having a valve reset, wherein the one or more gas shut-off valves are operatively connected to one or more appliances within the building, and wherein the one or more gas shut-off valves define an open position and a close position;
wherein the one or more sensors further include an ambient sensor to detect the presence of gas in the building;
wherein upon the detection of the presence of gas by the one or more sensors, the sensors providing an operation signal to the one or more gas shut-off valves to move the one or more gas shut-off valves to the closed position and to provide an alert signal to the one or more light indicators; and
wherein after gas is no longer detected by the one or more sensors, the one or more sensors providing a valve reset signal to the valve reset on the one or more gas shut-off valves to make the one or more gas shut-off valves operable, the sensor signal provided to the valve reset before the one or more gas shut-off valves can be moved to the open position.
