Mains fed fire alarms

[Pocster]

I need to order these up. So have 2 core + earth to each location.

 

6 fire, 1 heat required

 

Looked at 

 

https://www.safelincs.co.uk/radio-interlinked-smoke-alarms/

 

But they are like £70+ each!! ( with wireless comms between them )

 

Any other recommendations???

 

Also need a carbon monoxide detector ( for log fire ) assume this does not need to trigger the others for an alarm ....

[Pocster]

Cheapest one

Can't seem to find any mains/wireless comms ones cheaper.

 

Just a case of suck it up then ?

Ah Google say not allowed.

Thinking about this . Can I just have battery powered wireless interlinked alarms ? 
Much cheaper . Doesn’t require a sparky to install them . 
I can just ignore my power cable to each alarm point then .

Regs in a domestic new build aren’t it *has* to be mains powered are they ??

The time to ask was before you plasterboarded.

 

2 core & earth to first alarm, then 3 core and earth from that to the next, and the next and the next etc.  No need for radio linking.  The radio linking bit costs more than the basic alarms.

 

Another vote for Aico.  If they are too expensive look on ebay but CHECK the "replace by" date if buying from ebay, lots of old stock about.

Aico or at a push Aico.

 

Saying that I have once fitted Kidde when I couldn't get Aico in a rush. Wired which were OK tbh if a bit bulky. 

 

You can with most get a little test station from where you can test your alarms or in the event of a trigger hush all those except the ones going off. 

 

Aico do really good installer/specifier pocket book guides for the sake of a 5 minute sign up.

So do they HAVE to be mains ?

Can I have battery but wirelessly connected ?

[Pocster]

This seems to say yes

The wireless aspect isn’t the real cost . As you can get battery fed wireless ones for 30 quid a pop 

[ProDave]

3 core cable is cheaper than wireless modules.

[dpmiller]

plus you can go hybrid- cable the easy ones, then wireless off them too. I chose to go wireless and to add the fancy test button and a relay box to integrate MVHR control and CO sensing.

No.  They need to be mains operated.  Buy the Aico ones.

Is there any way at all of getting black smoke and heat alarms for a residential house without needing to go industrial with panels etc?  I saw so many when I did an initial look but after calling a few online stores none know of any domestic sensors that will meet UK regs (i.e. mains powered with battery backup)
