Abstract
Briefly, apparatus and methods for detecting and terminating production of undesirable gases, such as carbon monoxide (“CO”), at a potential source, such as a household appliance. The apparatus and methods may determine a threshold level of the gas. In one embodiment, the method and apparatus may determine whether to provide power to a power supply input of a controller of a potential gas producing device based on the detected level of gas, where providing power to the power supply input of the controller of the potential gas producing device enables the controller of the potential gas producing device to provide power to the potential gas producing device. In another embodiment, when gas concentrations about a potential source are above a maximum threshold, the system communicates with a fuel supply valve of the potential source to cause the valve thereof to interrupt the supply of fuel to the potential source.
