Do Your Smoke and Carbon Monoxide Detectors Work?
By: Inspector Bill
SMOKE AND CARBON MONOXIDE DETECTORS SAVE LIVES
It is a no-brainer that smoke and carbon monoxide detectors save lives and protect your family. However, do not rely simply on the presence of a detector. All detectors need routine maintenance. This includes replacing batteries regularly and periodic testing. Additionally to most folks surprise, detectors have a 5-10 year functional life. Yes you read that right: both smoke and carbon detectors must be replaced occasionally to maintain protection for you and your family.
DETECTOR BATTERY REPLACEMENT
If the detector uses traditional batteries (usually a 9 volt), at a minimum the batteries should be replaced once a yer. Some newer detectors utilize a non-replaceable lithium battery that is good for 10 years. One of the leading manufacturers, First Alert, recommends replacing the batteries every 6 months. As an inspector I prefer the 6 month guideline. I recommend replacing all smoke and carbon monoxide batteries in April and October. This means the battery is fresh entering the heating months–and the Christmas lights season!
DETECTOR TESTING
Detectors should be tested once a month. Most (if not all) detectors have a test button. Simply depress the button and you should hear the audible alarm. If the detector fails the first step is to replace the battery and check again. If replacing the battery in your smoke or carbon monoxide detector does not fix the issue, the detector should be replaced immediately.
REPLACING DETECTORS
All detectors begin to lose sensitivity over time until eventually they do not function properly. Every detector now comes with its life span and date of manufacture clearly written on its label. If a detector is past its life span then its ability to do the job is compromised. Please check your detectors and replace them if they are out of date.
FINAL COMMENTS
A note to our elderly, financially challenged, or physically handicapped folks, many local agencies and fire departments have programs to assist you. If you can’t physically perform the mentioned tasks or can’t afford batteries or detectors, please check with your local fire department.
You and your family are priceless, By following these simple guidelines for smoke and carbon monoxide detectors, you may save yours or someone else’s life!
This detector is clearly marked “REPLACE IN 10 YEARS.” By the manufacturer’s own standards, the detector should have been replaced in 2015. At the time of inspection in 2022, it was seven years past the expiration date.
