Aico smoke detector wiring

[gazdkw82]

Just about to start pulling in the cables for my smile detectors, however I dint have the detectors yet. Is there enough room in the terminals to terminate a supply feed in and then loop out to the next detector or is a junction box required to house the feed and a supply taken from every J/B?

I think there's enough room.
This video by JW shows early on the connection area which i believe is common to all AICO units...I have some smokes and a heat and they all look the same, but mine are wired as to 1 hard-wired in hall, and the rest radio-linked.

You can get 2x 3 core and earth cables in and/or a twin and 3 core in no bother.

I used to put a round dry line box behind Aico alarms, otherwise the wires were exposed from the sheathing, if you get my drift.The mounting plate is quite thin.

PS I would include an isolator switch in your installation.

They are not exposed, there’s a cover over the cables, there’s no cables exposed once the smoke head is removed.
I think you’re thinking of the wrong manufacturer

think hemeant where the cables enter from the back. you need to keep the sheath stripped part quite short.

There’s loads of room, no issue getting cables in with the sheath entering the enclosure, absolutely no need to cut a dry liner box in the ceiling,

i'd not call this loads of room when you have a T/E and a 3C/E in there. just about enough.

Well aye there is, I’ve never had an issue and that’s using 1.5 mm or 1mm cables.
Cutting a hole in the ceiling is not the way to go.

Loads of room! My house is smaller than that!
Oh, wait...maybe that's not to scale?

 

[telectrix]

me neither, but you need to strip back no more than 1" of sheath. or it's difficult to get the cover on. that's probably why i find a few knocking around the bottom of my toolbelt.

Best smokes on the market in my opinion.
They’ve never seemed to have changed much over the years.

funny that. last week replaced a duff one. bungalow only had 2, both square. tight fisted client would only stretch to replacing the faulty one, then complains he can't obtain a square one and the new one exposes the 30 year old patch of wallpaper on the ceiling that was under the detector. still allcredit to aico for making them compatible with ancient ones.

I could never get the rectangular type smokes square haha

My point is, can you get x2 t+e cables terminated in it? Feed in and feed to next detector?

Yes, even I have managed it easily with 2×3&e.

Can't leave long tails though, just an inch or so.

Are you using twin, or three core - need the third line wire for inter-operation /linking of alarms. (Unless paying for the additional wireless option)

Yes , I said earlier

Sorry, I meant 3c+e

Does everybody use 1.5mm for their dedicated smoke detector circuits?

Yes if it’s it’s own dedicated circuit
