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.

CAVIUS has put these steps into place to rectify this problem, with the four largest DIY stores in New Zealand.

Enter the first 6 digit Batch Code, shown on the under-side of your smoke alarm, into the box below.

If your alarm is in the known batch, we will send you an email to print and take to any one of the four nationwide stores below for replacement.

Once you receive the email, please:

  • Print out the email.
  • Take only your smoke alarm (do not remove the mounting base from the ceiling) and printed email into any New Zealand branch of Mitre 10, Bunnings, Placemakers or ITM.
  • Give the ‘Customer Service’ desk the email and smoke alarm(s). They will replace your current alarm with a brand new alarm – no questions asked.

The Kiwi and global CAVIUS teams apologise for the inconvenience. However, we hope it confirms our commitment and support to you, our customer.

If you have any queries, please do not hesitate to contact us via email on support@cavius.co.nz or call 07 573 8670.
