House associations replace smoke and heat detectors every 10 years and it is amazing that home owners could have detectors for over 20 years.
Usually a smoke or heat detector comes with a 12 year live span from production. This allows for 2 years storage in warehouses and wholesalers.

Having out of date smoke detectors can void insurances but why take a risk to you our your family.
