Do you really need to replace smoke detectors every 10 years?
Smoke alarm lifespans can vary, but according to the association, smoke alarms need to be replaced at least every 10 years. According to Carli, that lack of awareness means some U.S. homes may have smoke alarms that have passed their expiration dates, putting people at increased risk in the event of a home fire.
How long do hard wired smoke detectors last?
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. Carbon monoxide detectors last between five and seven years.
Do smoke detectors expire?
Smoke Alarms Eventually Expire
Just like that milk sitting in your fridge, smoke alarms go bad after a while. The National Fire Protection Association recommends that you replace your smoke alarms every ten years.
Can I replace just one smoke detector?
Yes, you can replace a non-wired smoke alarm with one that requires electrical power connection to the home wiring. Of course, you may have to hire an electrician to run the wires to the location where you need to install your new “hardwired” smoke alarm. My old fire alarm only has two wires and my new one has three.
