Does a carbon monoxide detector go off continuously
Zielflug [23.3K]

Answer: CO alarms have a life expectancy of around seven years. The CO alarm will beep every 30 seconds or display ERR or END. If a CO alarm is at its end-of-life, replacing the battery will not stop the beep. Most detectors will beep 4 or 5 times in a row about every 4 seconds. Do not mistake dangerous levels of poisonous gas for a detector with low battery.
