Abstract
Apparatus for testing the operation of a carbon monoxide alarm of the type having a casing and a CO sensor extending therefrom, includes a housing sized and configured to receive the casing and to form a gas chamber in communication with the sensor, a source of CO gas, comprising a flammable substance which generates CO gas when burned, and a holder located within the housing for holding the source while the source is being burned. The CO source generates a concentration of carbon monoxide gas within the chamber which is above a pre-selected threshold for a sufficient period of time to trigger an alarm condition.
