(most alarms have no way to test the sensors when you press the test
button)

Is there a similar aerosol or method of thoroughly testing a CO
detector?
I couldn't find anything from a web search

Thanks

Johnstone Supply sells a aerosol to test detectors.

I doubt that a CO detector owner would be a smoker, but would a puff of
cigarette smoke blown at a detector set it off?
