The whole BS standards should look like this guide,... wonderful...

The guides are concise, well illustrated and easy to understand. Trouble is they only tell part of the story and the danger of such guides is that electricians will use them to design a system rather than working to the full picture. For example it pays scant regard to ceilings with closely spaced structural beams.

Gents, I have a studty question i keep getting wronng and i'm starting to tie myself up with it!! I've been asked  "if a local authority has fitted battery smoke alarms and they have  had a number of deaths due to batteries being removed in two storey dwellings  what recomendation based on BS839-6 would you give to ther future policy", and what is the current set up in grade catergories they have inj place

Well i have recomended System LD3 (Part 6) Detectors are installed in all circulation spaces that form part of the escape routes from within the dwelling, such as the hall in all there properties, but I cant find any information on the later part  "and what is the current set up in grade catergories"

Any advise chaps?,

Hi Tony - I don't do Part 6 but reading from it in relation to 2 storey buildings the Grade F - (batt only alarms) only really apply to private dwellings of less than 200m2 that are either oqner occupied up to 2 storey or rented single storey or flat.

thank you!

Tony,

Have you tried recommending grade E (mains wired) or, better still, grade D (mains wired with in-built battery backup)?

Part 6 suggests LD3 in this scenario. Unless the building is not built to a standard such as ADB or 5588 part 1 - In that case it suggests LD2. Translating this into practical terms I would suggest that if a 2 storey house lacks a protected escape route AND lacks window escapes, then LD2 would probably be necessary.

"and what is the current set up in grade catergories"
the current set up is a grade F system.

But would a 2 storey house not lack a protected escape route anyway as the norm?
