230v smokes interlinked through multiple shops

[Jdsparky]

If he is insistent on mains smokes other than a proper system, the following solution could help i think

Each CU zone have its own circuit of 230v interlinked smokes with one base as a radio base, link all radio bases together wirelessly and i think the system will work as it does now, doesn't stop people isolating their part though

Ive never tried this set up but I'm sure it should work, anyone feel free to correct me if I'm wrong

Good solution, but still think it should be done the right way for future proofing when someone replaces with a normal smoke/heat detector.

You have a Commercial / Residential property here which will require a specific level of protection while avoiding nuisance alarms, you have private areas as well as public areas and also to consider is the fire protected rating of the building; its likely this building will require separated systems but without knowing a lot more its hard to say what is required so members should refrain from shooting in the dark here without posting relevant regulations.

Ive just done some student flats that have a 230v wired independent system in each flat and a conventional fire system in the communal areas.... a fire in any flat will not alert the rest of the complex unless the smokes in the communal areas are activated or a call point is operated.

I have also done systems like that as well, there is no communal areas, they're all separate entry apart from flats which as you can imagine go up a flight of stairs then two separate doors.

I have to admit i prob wouldn't consider doing it the way i suggested, a proper spec 24v system is the way to go, the last one i did was a shop with flat above, flat was existing and shop was being refitted, i was going for a sounder in flat linked to system in shop, fire officer said that wasn't necessary, based on that you maybe be to get away with 230v smokes independently fed in each flat with a 24v system in each shop

I will have to see what fire officer has to say for himself then

This been a commercial and domestic set-up combined with communal areas too (stairwells) i cant comment without a lot more info and you need to consult the relevant BS fire regulations for combined commercial and domestic use buildings, the landlord would also need to relay all the structural fire precautions within the building as this too reflect on the system required.

If each building is totally seperated, with the own entrance, then each building must be treated seperatly....A local Authority report/assessment will determan if each system must be interlinked. If they are commercial shops, then a full part 1 system will be required. To obtain a licence as a landord...the assessment must have been conducted..???

 

[Jdsparky]

The shops are food businesses so I presume greater fire risk than most, I'm not sure about the past although he has said it has been passed and certificated for a few years previous, I would also think there has been an initial assessment when he first acquired the properties but not sure so will ask him about it tomorrow.
and yes each part is separate apart from entrance to staircase for two flats.

Suggest getting in local authority to clarify....as i can only seeing on way for this, a control panel in each building covering shop and flats, reason being this is not communial domestic premises, the flats are over commercial buildings giving high risk.
Each panel may also be asked to Bi-linked between buildings. This is what i would put forward, but this my own opinion
