How long do BRK smoke detectors last?
eight to 10 years
The Lifespan of Smoke and Carbon Monoxide Detectors Most smoke alarms have a lifespan of eight to 10 years, and again, replace the batteries every year. A smoke detector with a lithium battery or a hard-wired smoke detector can last 10 years, at which time you would just replace the whole unit.
Why does my BRK smoke detector keep beeping even after I change the battery?
Newer smoke alarms keep some errors in the processor. The smoke alarm must clear errors after the battery is changed, but it might continue to chirp even after you change the batteries. When this happens, the way to stop the chirping noise is to reset the smoke alarm to manually clear the error from the processor.
Do hard-wired smoke detectors go bad?
“Replace all smoke alarms, including those that use ten-year batteries and hard-wired alarms, when they are ten years old or sooner if they don’t respond properly when tested.” Most CO alarms expire after 7 years, so if you have a combo smoke and CO detector, you should replace it every 7 years.
