Easichange® Replacement Smoke and Heat Alarms

Smoke alarms and heat alarms need to be replaced after 10 years. Easichange® chooses the best smoke and heat alarms to replace your old units. In many cases the kits allow you to replace your alarms yourself, without the need for an electrician, and will include all of the tools and instructions you need to perform the job quickly and easily.

Please Note: When a manufacturer discontinues a smoke alarm range it may not be possible to replace your old alarms without an electrician. In such cases easichange® will select the best option for your replacement alarm, ensuring that it will continue to work with the rest of your alarm system and enable you to replace a single alarm without worrying about compatibility.

Replacement Smoke Alarms

Replacement Smoke Alarms

Our easichange® replacement smoke alarm kits are designed to help our customers replace their old smoke alarms in the quickest and easiest way possible. Where available we have created kits that contain replacement alarm heads that will directly replace your existing alarm, and included all the tools and instructions to allow you to swap them over yourself, without an electrician. Where this is not possible, we have chosen the most suitable alarms and accessories, ensuring that your new alarms will interlink with the old models. In these cases you will need an electrician to install the alarm supplied in your easichange® kit.
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.
