ABSTRACT:
An apparatus for and method of detecting fires comprising detecting (with one or more detectors) levels of carbon monoxide, carbon dioxide, and smoke in an ambient environment, computing (using a processor) over time rates of increase of each of the levels, and generating an alarm if one or more of the rates of increase exceed predetermined threshold rates of increase.
