It is possible that you are on this page because your smoke alarm has started beeping indicating a low battery.
This might mean you have our original 5 year model and it’s time to replace the battery. It is easy to identify a 5 year CAVIUS alarm – the battery is visible and removable – as seen in the image on the left.
If your alarm looks like this then it is likely the 5 year battery has expired. Please call our Customer Service team 07 573 8670 to purchase a replacement.
If your beeping alarm isn’t the one above, it may be from a small faulty battery batch which has been recognised by CAVIUS. The battery itself is not faulty and will last 10 years. However, it is sending a message which makes the device think it is going flat, despite it being fully operational. This isn’t ideal, so we need to replace it for you.
At no time has there been any risk to anyone using this device as the battery will give a 30-day low battery warning before it is completely flat.
