Smoke alarms have a limited life and must be replaced every 10 years.

Over time they accumulate dust, insects and lots of other airborne contaminants. This will compromise their efficiency and sensitivity. So it is important they are replaced to ensure the safety of your home and family.

How to know when your smoke alarm is expired

All smoke alarms have a way to identify their age.

It could be a batch date like 220614 (see image below) which means it was manufactured on the 22nd of June, 2014. Or, it could be an expiry date which indicates when they need to be replaced.

In the case of the smoke alarm below, both dates are shown near the battery compartment.
