How many fire alarms do i need to install on a 3 bedroom house (2 floors)

[Des 56]

Lenny should be on Myth busters
Given the myths that are around

Assessing the risk and responding by siting alarms where needed,Bs5839-6 is a document that perhaps all who work in domestic should hold

Totally agree Des.

Relevant guidance documents should be held and referenced by EVERYONE involved with installing these or any kind of unfamiliar system.

More so with fire/smoke alrms IMO as you are trying to save someones life!!!


The guesswork evident worries me to say the least but, at least, you can always use a bloody phone app if you're not sure!!!!!!!!!!!!!!!!!

sorry topcat relating to this post....... dl2

Well, this thread is a bit of an eye opener to say the least.

Jst goes to show the lack of knowledge/confusion that exists regarding fire protection & alarms etc.

Although Approved Document B currently states that a Grade D LD3 should be installed, it also states that BS 5839-6 should be followed and this standard recommends a Grade D LD2 system.

First off they are CO (Carbon Monoxide) not CO2 (Carbon Dioxide) alarms and they SHOULD NOT be interlinked with standard smoke/heat alarms as the sound they emit when detecting CO is different to smoke/heat and YOU MUST be able to differentiate between the two i.e smoke from a fire and CO.

A new build or materially altered building would normally require a minimum of a Grade D LD2 (BS 5839-6) system which covers all circulation spaces that form part of an escape route and rooms or area's with a high fire risk. These area's cover hallways & landings, the principal habitable room and will require a smoke alarm.

Kitchens will require a heat alarm.

A fire risk assessment will determine the exact level of cover reequired but as stated BC will tell you what you need which nowadays in my experience is a Grade D LD2.

When someone uses the word "Fire Alarm" I tend to think of the typical zoned, pyro / FP200 cabled installation you would find in a industrial or commercial building. I have installed Fire Alarms in domestic properties but normally HMO.

I find calling them smoke/heat detectors when describing domestic installs much softer on the pallett :smart:

And much easier to install!

Aico pocket guide has everything that's needed in it, from new build to existing properties, of different sizes too.

Its even on a slide chart at the back. Fit as this then your system will comply with whichever standard it states. Also a page regards using the risk assessment to determine if more or less alarms are required.
