When Should Smoke Detectors Be Replaced?

Replace the entire smoke alarm every 10 years.

How do I know if my smoke detector needs replacing?

Check the date
  1. Remove the smoke detector from the ceiling.
  2. Look on the back of the device for the date of manufacture.
  3. Remember that smoke detectors should be replaced 10 years from the date of manufacture.
  4. If it's less than 10 years old, put the smoke detector back on the ceiling or wall.

Do you really need to replace smoke detectors every 10 years?

10 Years Smoke Alarm Requirements

Smoke alarms have a limited lifespan. The National Fire Protection Association (NFPA) recommends every smoke alarm be replaced after 10 years and that regular batteries be replaced every six months.
