Carbon monoxide alarm

[z28]

Very concerned as to why after 3 days of use the alarm was sounding in our 2018 ACE 30.3
I was using the generator the entire time and no issues for the first 3 days. I contacted Thorn and they advised me to air out the coach. I did this but after resetting the alarm it would go off within 10 minutes. Finally after 6 times of resetting the alarm and having aired out the coach it no longer sounded. I am concerned as to what the cause may have been . Anyone have any thoughts?

Low battery voltage well cause the alarm to go off.

Thanks that’s what I thought
I’m glad to hear a confirmation to my feelings

Doubt if it's the case here, but the day we picked up our MH, the CO alarm went off, apparently caused by a seat cushion that was propped up against the alarm. It may have been detecting off-gassing of the foam in the cushion, and reset after we moved the cushion.

Our previous MH's alarm would "chirp" every couple of seconds when the batteries were low.
