Last year I put a CO Guardian in my Bonanza. I didn’t bother to take the button card down. On my last flight, the Guardian had a yellow warning light come on. No red or flashing red bit just a notice of a trace amount of CO. The card showed nothing.
No heat on, nothing different than a normal day with usual ventilation.
So I pulled the scat hose from the heat muff to the air box for my first search. The picture shows what was found on the backside. It looks cut, most likely a rub when the new engine was installed. So when I put the new one on, I will make darn sure it is clear from any potential edges that can cause a repeat.
Point is, carbon monoxide can show up when least expected. Please review how can identify it.
If you are using a button card, do you trust it? I don’t.
