Malfunction signal - Component failure. An intermittent "chirping" alarm will sound every 30 seconds, and an "Err" message will appear on the digital display. The only solution is to discard it entirely and replace with a new gas & carbon monoxide alarm.
Correct. Intermittent beeping is a sign of "component failure". Time for a new one.
The sense is bad, unfoturally the unit need to be replaced.
