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

[i=p/u]

no gas and open fire doesnt get used.. its a small bungalow being converted with 3 bedrooms up. all bedroom doors are next to each other , so one smoke there in small landing, one smoke at bottom of stairs where all doors are within 3-4 meters of eachther and a heat in the kitchen.

ionisation or optical??? goig by that website i should go for optical. is a good few pages(adico)

Sounds good

Its really up to you what you put in

I would use the multi or optical - the ionistion is only really good for smoldering clothes and realistically you wont have much of that.

Check this out
What works where?Aico - Fire & CO Detection & Fire Protection Specialist

This is a good guide

yeah was reading it, good guide for a punk like me wanting t wire the world but my heads sore trying. good guide consider it saved in favourites ty

Dont forget you have to do a risk assessment to determine what is the best and what locations.

Dont forget the following:
Smokers
Open fires
Utility rooms
Electric heaters (inc Eco 7)
Electric/gas cooker
use of candles


use your common sense with them - work out which are in use more than 10% of the time and count them in, the others put a low likely hood on them.

As your N/Ireland I would be happy to pop across and help with the RA as I used to teach councils and H&S officers/inspectors how to carry them out - pm me if your interested

No one has mentioned the lounge, i thought the lounge had to be covered as well as hall, landing (within 2 meters of bedroom doors) and kitchen?

 

[Spazz]

lounge is the same as the living room

If this is a new build or conversion, then building control will have the say of what is to be installed

 

[firemanowl]

If in doubt check with building control as they will be signing it off. I'd avoid putting too many in as this leads to them going off for no reason and the owners then try and disconnect them.

Interlink the CO2 alarm in with the lot as well - always dread CO2 leak and you cant hear the bloody alarm because you closed the door.

If its a bigger house I have installed a sounder upstairs for the CO2 alarm before instead of interlinking them.

Why would you fit Carbon Dioxide (CO2) alarms ?

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.

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

 

[Guest123]

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!!!!!!!!!!!!!!!!!

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.
