A First Alert® carbon monoxide detector life span is warranted for 5 years. After 5 years any detector should be replaced with a new CO Alarm. Alarms may have an actual life span that is shorter due to environmental conditions and may need to be replaced sooner. Test them weekly and if a problem arises while still under warranty, please call for a replacement. Batteries should be replaced as needed for those alarms requiring them.
