Domestic extention and smoke alarms

[Dunk17]

Afternoon all,

Ive looked at the building regs but can't seem to find anything, i remember reading something that said when fitting smoke alarms off a lighting circuit you need to put some form of isolation in, is that correct?

I'm also looking to install nest alarms, do they all need to be wired?

Thanks for your help.

So it's only applicable to the extention not the whole house? If so, installing wired in the extention and battery in the house linked would potentially satisfy LBC?

You'll need to clarify with your LBC. With a major alteration or extension to a property, BI's can get a bit picky, and start applying particular building regs to the whole property. I had to install & link fire alarms to my whole house (basic level), when I had an extension done some years ago. Has the extension had building regs plans done? It might show them on the drawings.

Smokes should be wired to a regularly used lighting circuit, I believe this is the recommended method in the BS.
This is to ensure that any failure of the circuit is readily identified and rectified.

I believe that it is actually either a lighting circuit or a dedicated circuit from the DB. But as I haven't a copy of BS 5839, I can't back that up factually. But you can search for the subject, which kinda confirms this;

A dedicated circuit is unlikely to be noticed if it trips, or fixed with any hurry.

Both are acceptable methods in bs5839-6 tho rented properties and hmo if applicable ,it is seen as better to do it from the lighting for the very reasons you’ve stated.

Thankyou for all your responses, they've been really helpful.

I have a friend of a friend that works for building control for a different council, he's said that either way is suitable and building regulations are only applicable to the extention. I will try and run a new circuit that covers the whole house and not just the extention, although it could be tricky to get to some locations without chopping the ceiling.

A secondary question... I'm looking at installing Nest, does anyone else have a prefrance of detector? It's my own home so I'm happy to pay a little extra for better quality.

It’s your preference, I understand Nest links into other products and WiFi , iPhone etc. Aico have an app, and are well respected fire alarm manufacturer.

Take your pick.

Nest don't have heat detectors, and for this reason I would avoid them.

I thought their 2nd generation does?

Not a standalone heat detector. I think it is combined smoke and heat which is no use.

Plus they are a ridiculous price for a domestic smoke alarm.

I love the Nest thermostat, but the smoke alarms and cameras are overpriced junk in my opinion.

I agree that the Nest Learning Thermostat is a decent product.

What product would you recommend? In terms of how they look I find most other products look great. Are there many product out there that have a heat/Co and smoke/Co?

I've never judged a smoke alarm by the way it looks, it's there to save your life not look pretty.

I have always fitted Aico alarms and never had a problem with them. They have a range of single and multisensor alarms to suit all domestic systems.

Whilst combined smoke and Co detection doe snake some sense, it's important to remeber that CO alarms may need to be fitted in different locations to smoke alarms to achieve the correct protection.

I agree that it's there for a purpose but if its in your own home surely you want the nicest product?

Ive used Aico previously and they've always been reliable.

In my own home I want the most reliable product, as long as it isn't ridiculously ugly.

Ei Electronics/Aico for me also.

I'd run smokes on their own circuit.
The reason being if the lights are ever isolated for whatever reason i.e light fitting change, earth fault etc, you still have that smoke alarm in operation if anything goes wrong.

But then again I'm only a trainee myself. ???
