Smoke And CO Detectors Don't Last Forever

Posted on November 18, 2015






Picture this: you are enjoying a peaceful slumber one night in your home, dreaming of winning the lottery and not having to get up for work tomorrow, when all of a sudden, at 2:00 am you are awakened by the sound of your smoke detectors blaring. You jump out of bed and think about getting your family outside to safety. Your heart races as you wake up the children and move outside. You are all out safely, waiting on the front lawn or perhaps in your car (why does it take a car so long to heat up?) for the fire department to arrive. The firefighters arrive and enter your home and do an investigation. You hope they don’t find anything wrong and after a few minutes one of them emerges from your home holding your smoke detector and tells you that it is past its useful life and that is why it went off. You respond with a quizzical “I didn’t know that smoke detectors wore out?”

I have been at this same type of call numerous times this year and those homeowners didn’t know that smoke detectors and carbon monoxide (CO) detectors have a useful life and then need to be replaced, so I thought I should write something to let everyone know.

The useful life of a smoke detector is 10 years from the date of manufacture. The manufacturing date is stamped on the back of the detector somewhere. A carbon monoxide detector only has a useful life of 5 years. If after looking at the back of your detectors and you can’t find a date, it is older than 10 years. After the useful life has passed, 3 things can happen: 1- the detector may keep working for a while, how long is just a gamble; 2- the detector will just go off for no reason; 3 some detectors may not go off at all, ever again. How do you know?  How many of us actually use the test button once a month to insure the detectors work as the instructions say?  How many of us actually hit the test button after we faithfully replace the battery in each unit every year?

Take a few minutes and check the manufacturing dates on your detectors to insure they are within their useful life and doing their job, protecting you and your family.
