Caerphilly: mains smoke alarms chirping or false alarming — what to do now
What mains smoke alarms chirping or false alarming involves at a Caerphilly address, what it depends on, and how we price it. Caerphilly and the CF83 postcodes are handled by the same electrician throughout.
Do this before we arrive
- Note which head is chirping — press and hold its test button to identify it before assuming it is all of them. Nothing here is optional.
- Frequently — check the replace-by date printed on the back of the head if you can reach it safely.
- Do not remove the head from its base and leave it off; that removes protection from that floor entirely. We will confirm it in writing.
For your own safety, alarm heads have a finite service life regardless of whether they still respond to the test button. Replacing them at the manufacturer's stated interval is part of keeping the system effective.
