Why do Smoke Alarms have to be replaced after 10 Years?

Why do Smoke Alarms have to be replaced after 10 Years?

A number of studies assessesd the impact of ageing on smoke alarms. A nationwide study was undertaken by the Consumer Product Safety Commission (CPSC) in the USA and found that after ten years only 73% of smoke alarms was still working. Ageing alarms may experience sensitivity drifting, which may, in turn, result in an increased frequency of accidental activation.

Canada’s Ontario Housing Corporation carried out a study supporting saying that after 30 years, nearly all the smoke alarms will have failed. They conclude that replacement after ten years, with roughly a 30% probability of failure, is an appropriate balance between safety and cost.

All our manufacturers recommend a replacement of the smoke alarms (or at least of the smoke alarm heads) every 10 years.
