What cable is required between these linked smoke and heat detectors, other
than power supply?
I am doing a refurb room by room and want to cover as many bases as
possible!

TIA

For some the link is by radio signal. Not necessarily a very helpful
answer I know, but I will be fitting 3 detectors soon - one heat unit in
the kitchen and a couple of smoke detectors elsewhere. The bases are
connected to e.g. a lighting circuit and are linked wirelessly. Cost
in the region of £100 for 3 IIRC

Depends on the models you're using. For example, are yours mains
powered (sounds like it)?

In my case I linked them using 1.5mm 3-core-and-earth mains lighting
cable, of the type normally used for 2-way lighting circuits or bathroom
fans etc. Two of the cores are used to convey power from the first
detector to the second (ie live and neutral), and the third (effectively
a switched live) carries the 'linking' signal between the two units.
The first detector of course is also fed from a 1.5mm 2-core-and-earth
cable wired to the lighting circuit (or preferably, wired direct to the
CU on a dedicated circuit)

Same here. I also put a non-maintained emergency light on the same
circuit. That way: (1) I get a light on the stairs in a power cut (2) I
know if the supply to the smoke alarms has failed (yes, I know they have
battery backup but...).

Mains smoke detectors normally use triple and earth including the
power supply, i.e. one additional signal wire interlinks them all.
Not looked at a mains interconnected heat detector, but I guess it
must be the same in order to link with smokes. AFAIK, there's no
standard for the signalling, so you must use all the same make of
detectors. You might want to buy them all at once, in case they go
obsolete half way through your refurb.

Take a look at http://www.aico.co.uk/index2.htm which should link to
their 'Radio Link' detection system.

It looks (to me) to be a simpler install than running 3C+E all over the
house. As I said in my first post I'm looking at installing a heat
detector in the kitchen and smoke detectors on the first and second floors.

(sorry to repost but I did not have the leaflet to hand)

Only having a quick glance at the website above I found nothing relating to
A radio link. I'm assuming the goal is to have all smoke/heat detectors go
off if say a fire starts in the kitchen you can hear it all the way in the
bath upstairs. I can't really say I'd feel comfortable having the signals
being sent wirelessly especially in older homes where the walls jam radio
signals.

For example I've got a wireless router setup with a computer in the other
room, the distance between the router and the computer is not but 3 or 4
metres a way but the wall dampens it so getting internet access in that
other room is quite tricky. Not sure if I'd really feel I could depend on
something like that.

I have the Screwfix ones with battery bases which are supposed to link by
radio, only they don't, even when close together (and yes, trying all
combinations of band switches). However although I know I should, I can't be
a*sed to complain because it's the only problem I have ever had with
Screwfix. Has anyone else had better luck?

More than that for radio linked detectors, the detectors themselves
are around £20 to £30 each and then the radio links are a similar
price. Unless you can tell me otherwise, I'd be interested if you
can.

Simpler yes, but expensive. I've used some of these in our flat in
London because there are only three detectors there however it's too
expensive for our house where we will have seven or eight detectors.

A nice extra on the ones I fitted was a mute switch so that after one
had activated and so triggered the rest they could all be muted apart
from the first one. Although my house isn't that big, 4 bedrooms plus
self contained annexe it certainly speeds up finding the cause of the
alarm. As someone else commented I also fitted an emergency light to the
smoke detector circuit, this is by the CU and mute switch.

What make/model of smoke detector are they. I want that feature but
the marketing puff never gives enough detail...

I've had a quick google and can't find my exact model but it is similar
to:-

The mute switch was something my wholesaler told me about and was not
mentioned in the blurb with the detector so it may be worth asking
around

The given link displays a black page with, slightly right of centre, 6
'buttons' in 2 rows of 3. Centre top says 'Radio Link'
