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?

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

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.

I prefer to fit a dry lining box behind them where possible, round or square works equally well.
You don't need to do it, and it is possible to connect them without, but it's just nicer in my opinion.

No, I would use 1mm for a 6A smoke detector circuit, same as I do for 6A lighting circuits.

I'm sure someone will be along to say that technically the minimum should be 1.5 as its not a lighting circuit, but I'm personally satisfied that the departure is no less safe.

it's not a "power" circuit either.

As a DIY Dave I fitted Aicos to my parents house, some time back, fed in 1.5 T&E and interlinked with 1.5 3C&E.

Tried wiring the first base when fixed to the ceiling and that wasn't a great idea, but no problem terminating otherwise. The only issue I had was that flat cables coming through a round hole might let dust into the detectors, which seemed less than ideal, so once the bases were in place a bit of intumescent sealant was used to close the small void.

Yes. But don't have three there.

Yes, same, thought I'd see how others felt about it

 

[Mike Johnson]

Arn't they just a charging circuit to keep the lithium battery topped up, in which case 1mm is sufficient.

Aicos best on the market every property should have them can easily fit 2 x 1.5mm in the terminals doesn’t matter if they are 1mm in my opinion though. And as for dust when they get serviced annually your meant to hoover them for that particular reason of dust ingress good point you made there ?

1.5 is what gets used for lighting in NI, so I had stuck with convention. The dust issue might not ordinarily have been on my agenda, but it's a really old house with a serious build up above the ceilings that are still lath and plaster. Areas above each detector were cleaned well, but I didn't think it would take long for dust to settle again. Given the price of each unit it seemed best to aim for the full 10 years out of them!

Yes definitely go for the aicos also doing the expert installer course is an eye opener and I recommend it to every electrician. Even though they have 10 year lifespan they are still meant to be serviced annually

Some years of work ahead before I could be elligible for an expert installer course.
