Abstract
A method for operationally testing a wall mounted electronic carbon monoxide detector by temporarily hanging a test enclosure over the installed carbon monoxide detector so as to define a closed space between the test enclosure and the wall surface, and introducing a test gas into the enclosed space to determine the operational status of the detector. Hydrogen gas may be used as the test gas and generated by wetting a wafer of supercorroding alloy in the enclosure.
