How do I check the age of my alarms?

Checking alarm life

Most of our alarms have a 10 year life, after which they should be replaced to ensure you carry on getting the best protection.

However, the person that installed the alarms in your home may not have left you with the details of the date they installed them, or you may have moved into a property with alarms already installed – so how can you check the age of your alarms?

Checking the date-code label

All Aico alarms have a date-code label on the side of them which tells you exactly when the alarm was made and also the recommended replacement date.

The four digit code shows you the year and week that the alarm was made. The first two digits relate to the year and the second two digits relate to the week.

Above this is the ‘Replace By’ date, but note that the date on the label shows the maximum life of the alarm and alarms should always be replaced before their life is up.

Replacing your alarm

If your alarm is coming up to its replace by date, it should be replaced. The first step is to find out the model number of the alarm that you have installed (see the What alarm do I have? Alarm Identification section).

Once you know the model number for the alarm that you need to replace, you can use the Where to buy section to find the details of your nearest stockist who will be able to provide a replacement alarm.
