Smoke alarm question

The minimum requirement is smokes in escapes routes only unless it has changed very recently. 

I offer heat detector in other rooms and leave it up to client to decide.

Not done any new builds with solar but did a job a couple of years ago with batteries in the roof of a single storey part of house and they wanted a smoke detector up there.

The LD2 system requires all escape routes, plus kitchen and most habitable room (living room.)

Presumably heat rather than smoke in the kitchen - otherwise it'll be false alarm city Arizona...

most habitable

Dry, warm, and draught-free?

I too attended an Aico day this week - very polished!

So BS 5839-6, etc. 3.28 habitable room any room in a dwelling other than a kitchen, utility room, bathroom, dressing room [sic] or WC.

3.47 principal habitable room habitable room (see 3.28) that is normally the most frequently used room for general daytime living purposes

That is where I struggle - by whom are these rooms occupied? We no longer have the family gathered around the fire in the front parlour reading, and listening to gramophone records. Take my daughter's home (Ma & Pa & 2 school-age girls.) The kitchen (with 'dining area') is where the family probably spend most time together, but that is not a habitable room!

Ma & Pa have their own offices and do some work in the evenings. The little girls do their home work after dinner. So multiple rooms are used most frequently. Perhaps they should all have fire detectors?

If in doubt, I suppose put one in. :-)

Also with solar would you put a smoke in a loft, this wasnt really covered. A solar team told me only if its covering the battery but the aico guy seemed to say if anything was up there including the inverter 

I asked about "loft space" - BS 5839 offers no definition. However, it says, 11.1.1 Category LD systems ... In 2019 it is increasingly common for electrical equipment to be installed in loft spaces, particularly in premises fitted with photovoltaic power systems and other plant (e.g. boilers). In such cases, a Cetegory LD2 system needs to incorporate a smoke detector within the loft space.

We discussed, the meaning of, "loft space". We concluded that it is a space beneath the roof which can be entered by an ordinary door or hatch-door, etc. However, if there are vertical partitions, the eves space on the other side is not part of the loft space.
