The answer to 'smoke detector replacement schedule' is that smoke detectors should be replaced every 10 years. Smoke detectors are an essential safety device in the home, but their sensors can become less reliable over time. The National Fire Protection Association (NFPA) recommends replacing all smoke detectors, including hard-wired and battery-powered models, after 10 years of use to ensure they continue to function properly and provide early warning in the event of a fire.
In addition to the 10-year replacement guideline, it's also important to test smoke detectors monthly and replace the batteries twice a year, such as when changing the clocks for daylight saving time. Proper maintenance and timely replacement of smoke detectors can help keep your family safe and give you peace of mind.
