Got one smoke alarm installed by…
Got one smoke alarm installed by electrician in 2023 and gone off last week 2026 (only 3 years). It was suppose to have 10 years lifetime with 5 years warranty. But i was told that the alarm was installed in the wrong place (loft) by a proper electrician.
The alarm has a 10 year life with a 5 year warranty.
However , from your information I believe it has been installed in an open loft , which we do not recommend as the alarm will be exposed to contamination which can lead to false activations
What an excuse.
