Mains operated interconnected smoke alarm

[Neptune]

I fitted these into my own house a few years ago when everything was ripped open and hence, am familiar with the process.
However, on this occasion I need to fit these into a property that I let out and I don't have access to the ceiling void on ground floor.

I was thinking about using trunking and wanted to check on what type of trunking is neat and recommended for this purpose. Also, how will this merge into the existing light pendant (standard light pendant hanging from the ceiling).

Finally, I assume that I will need to trunk to the switch and not light if that's where the permanent live is. If this is the case, how will the trunking merge into the existing light switch?

Never had to use trunking before. Thanks in advance.

I can query again but the lady from council was categoric. The interlink should be cables and not wireless.

Perhaps talk to your local Fire Brigade prevention officer.

Should say "Fire Brigade, Fire Prevention officer"

- Thirdly, whilst the smoke detectors need to be daisy chained with the 3 core and earth cable, how do I install an Aico Fire Control Switch?

Request to see the evidence to support Thier stance. If they can't provide it, ignore it, if they can't find it to show you then they won't find it to hit you with either.

We install Aico alarms only

The mains bases have a bit that snaps out to allow YT2 mini trunking.

Also- BS5839 Pt6 has been updated to allow 10 year sealed radio linked detectors.
As others have said - ask the council officer for documentation requiring the mains only ones

The 10 year ones do work and last- the Aico ones even bounce the signal from one detector to others in a 'mesh' type of system. This way if the alarming unit is almost out of range of the furthest unit the ones on the way pass the alarm signal on (as well as the silence signal)

Asked a number of times, what Council is it that is insisting on wired alarms?

Hi Guys,

The LA is Bucks. I could have gone back and challenged their view on this. I appreciate your help with this.
In the interim, I was able to identify a route which has minimal trunking on display. All of upstairs is free of trunking as the power and interconnect cables are routed through the loft. The interconnect cable downstairs is run through a cupboard in the landing and I've also been able to minimise trunking that is visible on the ground floor.
I have complete trunking and cabling and now need to fix and wire in all the detectors. I have not connected the power supply yet.

Will share pics once complete. Thanks again.
