Grade A LD2 (Three Storey HMO)

[Tadees]

It is as clear as mud in the BS, Lacors & the Sleeping Guide whether the heat detectors in the kitchen and living room of a bedsit in a 3 storey HMO should be linked to the communal system. 

Lacors clearly implies it, the BS kind of implies it (when read as a whole) and the Sleeping Guide says there is no need.  I guess it has to be determined on the basis of a FRA, but it would be nice if all guides said the same thing, or is that too difficult?

Too difficult.

Dont worry, the smoke detectors in adjacent rooms will probably go off first anyway

I think the guidance deals with different situations so it cannot be definitive it is left up to you, as a competent risk assessor, to select the best situation for each case.

All well and good until the EHO acting under the Housing Act starts to put his pennyworth.

If it really is a  BS 5839-6 compliant Grade A LD2  system then one would expect the detectors to be interlinked?  This is the technical standard for such an alarm system. The other guidance documents referred to are building design / risk assessment guides and as a result of the fire risk assessment it might be concluded that variations from BS 5839-6 are appropriate, in which case they should be documented as such.
