Carbon monoxide alarms have a limited life, typically 5 to 7 years (some even less). Most people donât realize they need to replace a $25 - $75 item after several years.
It is recommended that you replace any smoke alarm and carbon monoxide alarm after being in use for 10 years. As electronic devices, smoke detectors are subject to random failures. In 10 years there is roughly a 30% probability of failure before replacement. After 15 years, the chances are better than 50:50 that your alarm will fail. That is too big of a risk to take. If your smoke alarm was manufactured in 2006 or before, it must be replaced! Replacing alarms after 10 years protects against the chance of failure, but monthly testing is still your best means of making sure your alarm will work. Regular testing of your smoke alarm is vital.
