10-Year Smoke-Only Alarms

A 10-year smoke-only alarm helps keep fire safety on your radar without the routine battery swaps that come with replaceable-battery models. In sealed-battery smoke alarms, the built-in power source is designed to last for the alarm’s service life, typically 10 years, so there’s no battery to pull out or replace along the way. That can mean one less chore around the house, but it doesn’t mean you can skip regular checks. Test your smoke alarms monthly, follow the manufacturer’s cleaning instructions and replace the entire unit at its end-of-life signal or sooner if it fails a test. As you compare 10-year smoke alarms, check whether “10-year” refers to the sealed battery, the alarm’s replacement interval or both. Power requirements and installation instructions can vary, and a sealed-battery model is not automatically a substitute for a hardwired smoke alarm where local codes require one. Smoke-only alarms detect smoke; they do not detect carbon monoxide, so plan for separate carbon monoxide alarms or combination alarms where needed. For home smoke alarm placement, install alarms inside each bedroom, outside each separate sleeping area and on every level of the home, including the basement. Follow the unit’s instructions and local requirements for ceiling or wall mounting, spacing and interconnected alarms, which sound together to help alert folks throughout the house. Keep placement clear of drafts and follow recommended distances from cooking appliances to help limit nuisance alarms without leaving living spaces unprotected. If you’re considering a smoke detector for a workshop, barn or another outbuilding, check its listed operating conditions first—dust, moisture and temperature swings can make a household alarm unsuitable for those spaces. Choosing a 10-year smoke-only alarm is just one part of a sound fire safety plan: make sure everyone recognizes the alarm, knows two ways out of each room where possible and has an outdoor meeting spot a safe distance from the building.
