geO Posted November 5, 2017 Share Posted November 5, 2017 My wife and I were out riding our bikes and when we returned our next door campers said they herd 4 loud beeps coming from our Oliver like every minute or so. We only had the A/C running so our dog would keep cool. I went inside and checked the alarms and everything seemed fine and it has not sounded since. What could have caused the Co alarm to go off? It was not chirping as if the batteries need replacement. Link to comment Share on other sites More sharing options...
