Fire alarm systems - Installation

[Dambo]

Hi Guys,

Is there a certain number of fire alarm sensors required per floor or per area? I can't seem to find an answer in big red, the onsite guide or the guide to the building regs.

Damien,

You won't find it, 7671 does not apply to fire alarm applications this is a different standard, but I can't remember the no. now even thought I have a copy as I dabble a little!

bs5839 if i remember rightly

Are we talking a domestic property single occupancy

Sellers,

That rings a bell, but IIRC there are different parts depending on the premises.

Not got mine to hand at the moment. As I have already posted I'm working on PUWER98 stuff tonight.

No, the place used to be a pub but it's being converted into a shop, with a flat on the floor above.

Then it`ll be to 5839-1 downstairs, and -6 upstairs. If the two systems are connected, it`ll all need to be to -1. You WILL need a copy!!

Where's the best place to get a copy of BS5839, Part 1 and 6?

If the system is to be zoned to BS5839-1. Then you shouldn't really have any more than 15 detectors per zone, and a single zone should not exceed a floor area of 2000 metres square.

what category system does the fire risk assessment for the building say?
