Really!!! Is that something that the designer should be picking up, none of this was mentioned by the council or the designer. Are you basing this on the risk assessed with the way the tenants live.Looking at the pictures you need a full system 2 stage set up where you have communal 'bed head sounders' in most rooms from the main panel, linked alert to a response unit (auto call out to fire brigade) .. unless station is close enough to negate a auto dial... the regs do state that full interaction is needed with building control and fire services and a mutual agreed system fitted.

Oh great!!! Got me panicking now as I quoted based on the council and the designers requests of what’s required (now the system is already installed) I’m now thinking I’ve either underquoted if it requires a lot More work or I leave it and left myself open should anything happen. Would I not be covered based on paperwork from the council stating there requirements and the designer commissioning the systemYour expected tenants can have a massive impact on design both cost and level of cover, this is all clearly set out in the standards, I just done a series of flats for ex addicts, crims etc and had to do a system that accounted for their condition, it added about 4k to the job but my arse is covered.. most people think there insurance will be a fall back but that will not help if they haven't followed the standards nor agreed with the local fire service and building control.. for the insurance firms any slight deviation from the regulations will void cover unless all parties agree on the design.

Ceiling beams are only an issue if the are 20% or above the floor to ceiling height in which case you treat them as walls.
@essex
Noted you have been handing out disagreements in this thread including mine which I have no issue on, I am interested why you disagree though, I simply was stating what the regulations state in this matter and the liasons required to cover ones butt.
Your advice based on photos cannot be verified. It is up for the Responsible Person to indicate the level of fire alarm required in the FRA. As no contractor is the RP they cannot ‘overule’.
The Op needs to request the FRA and no doubt this will detail a Grade A, LD2 system that has already been mentioned by the op.
This system is a domestic system so that indicates to me that this building is either a HMO or a building of over three storeys as per the Standard. However it may just be the case that the LBA just have a blanket policy of this system in all its properties.
This system requires detectors in all circulation areas that form part of an escape route (corridors and landings for example) and rooms of high risk (kitchens and communal living areas). The FRA should detail what rooms would be classed as high risk.
It is also worth noting that even though this is a Part 6 domestic system that is being specified due to the classification of a Grade A system it must be installed to the same specification as a Part 1 system. Standard FP should be ok but it could be the FRA requests enhanced cable to be installed.
Sounders in every bedroom is a certainty to meet db levels and there should be a minimum of two sounder circuits.
An auto-dialling system is certainly not required in this instance and is not a requirement of Grade A LP2 systems.
To answer the op, commissioning of the fire alarm will involve looking at the FRA, looking at the design and ensuring the installation reflects this. Then ensuring the fire alarm system operates as it should. In your case I would consider it prudent to engage the sub-contractor to do the commissioning so you can be certain theninstallation is acceptable.
The photos to me are glaringly obvious that there is drug abuse active in these flats, that is all I need to take from the photo unless you disagree with that evaluation?
Some of the points you raised were reflected in my later posts, the OP posted a picture of the type of tenant we may expect could be in these premises, now give the council recommendation was LD3 I do not believe this reflected the nature of the tenants unless there was info' that hasn't been disclosed here. In reflection of the possibility or probability that tenants are drug users etc then the system installed should reflect the added issues that this comes with.
I cannot vouch for his local building control I'll give you that nor can I know how they gauge their requirements but I can give an informed opinion on recent systems I have installed in HMO's where this is a typical type of tenant and I have fitted a system I suggested which reflected the higher risks associated with the tenants behaviour, since fitting this system 6yrs ago there has been 2 fire events caused by tenants on drugs which were dealt with fast and efficiently with no loss of life and just minor property damage, it was the fact the system was a mix of LD1 overlapping a grade D system to the flats that the tenants got out in the effected flat, an LD3 may have seen loss of life to those in the effected flats had they not had there own independent system installed.
PS - cheers for expanding on your disagreement, it is nice to know other members opinions be they negative or positive, this is how we learn, I am a stickler when it comes to members hitting disagree then posting nothing unless it is clearly obvious exactly what you are disagreeing with, in this case I needed more info so hope you understand me calling you out on it.
