Connecting new Smokes to existing on Extension.

[Kevin Terrans]

Hi all, just fitted out 2 storey extension to house and BC asked if new smokes were interlinked with existing smoke on Landing.
Existing is Battery only, do I have to change existing? If so, does that go onto fitting new to Kitchen/hall aswell?
Can't find anything in Building regs.
Thanks,
Kev.

if BC want interlinked, then that's what you need to do.don'tforget to fit a heat rise in kitchen. you can get 10 year battery units that interlnkk wirelessly.

I don't agree with just going with what BC wants, I just want to find where that point is in BS.
Had many run ins with this so called Inspector & been doing this for over 40 years and not wanting to back down as he can't tell me where he thinks he has seen this.

It possibly comes down to what parts of the house are covered under the building notification for this job as the bit that is being approved by the inspector. In theory that would be only the new part - but if beams were installed into existing areas to then that might get more fuzzy.

The reality is that it's usually easier to do what the inspector says as it can be expensive and complicated to get things through any other way.

But with a recent loft extension for a bungalow, all they seemed to worry about was that they were there in existing parts of the house, not that they were interlinked.

With battery interlink ones now it's likely the best investment in any case, just for peace of mind, especially if bedrooms are on the top floor which likely would not hear a stand alone heat alarm in the kitchen.

Agree, very fuzzy. I think 1 interlinked in old landing to extension will do as stairs is to open plan 1 room with exit and to kitchen with back door.
Very small new 2 bed.
Thanks for reply.
