Fire alarm

[Havvy]

Hi everyone I need abit of help!! I have been given a job no need to price just given so can't turn it down!!haha I just don't know too much about fire alarms.
it's a 3 storey house with 5 flats in it with a communal stairway and kitchen.
could some please help me with the design please!?

heat detectors in each flat,
break glass on top and bottom floor and exit in kitchen,
heat detector in kitchen with sounder,
Smoke detectors in communal stairway with two sounders.
thats what I think??
Any recommendations on how to wire would be good too!
sounder circuit,
then split the rest in to 2 circuits.

i will have someone to counter sign what I do!!
any help would be great or tell me what am doing wrong!
thanks craig

You have to have 2 sounder circuits if your doing a conventional system

 

[ayjay]

Have you read Tazz's thread yet? if not please do, everything you need to know is in it

You need to give this some serious thought, remote indicators, call points, slave panels are just three items you have not thought of, I would pass this up mate as it is one awesome resposibilty, and given the size it may well come under the local fire safety enforcement officer, I always involve them from the get go

This sounds like standard HMO, Grade A...heats in all flats plus you will need solo mains smokes in each flat for local warning.
No need to pass this up, as local orthority will have done all the fire risk assessment for you, for the HMO licence. Best way of installing this is a twin wire system, Kentec Sigma, or Haes Excel , both panels will take any detection make on sav bases, ie Apollo S65, Hochiki etc. Using this system will allow you to wire one fp200 to each floor for both sirens and detection, saving time and expense. After wiring ground floor, you will only be taking 2 fps to first floor and one to secound floor loft, so worst case is a 25x16mm trunking.

emergency lighting too ???--- duhh!!
honestly, i get really pis-d off-at most of the idiot posts on here
how some landlord can ask a clueless dipstick to install such an important thing is beyond me
--------------

i mean someone comes onto a forum tells that they know sweet f/a about fire alarms and asks others how to do it is beyond comprehension

Another DIYer or builder not wanting to give the job to a qualified electrician.

 

[tazz]

I am presuming this guy is a electrician, and as stated, all risk assessment, including fire, em lighting, fire doors, extingusher are all set out under the HMO licence. The local fire officer and local HMO officer will have already sorted the requirements out, including drawings.

unlightly tazz

 

[tazz]

To be honest Ayjay.....his statement of whats required is straight off a HMO report, he knows its a Grade A, he has got the heat detectors in every flat right. Now most would be posting on here "Fit Aico Wireless there great" and some of the replies have not been much better. But as you know I would aways help any electrician out

 

[ayjay]

but is he an electrician tazz?
i spent years installing fire alarms as a subby the last one i did was at b@q castlelepoint

 

[tazz]

I am reading between the lines, that he is....or seems to be..so have given the benifit of the daught.
I see you are not at present an Arms member, maybe worth requesting access, as a design engineer, we have many threads and discussions on HMO and construstion fire design an installation, maybe of interest.

This is easy. A conventional system is just loads of radial circuits in FP200 with EOL capacitors and resistors. Just make sure you the fit equipment as per the regulations a.k.a correct heights and distances, etc. I'd take the job. Yas.

So a load of radial circuits installed in somebodys property, with no thaught of how to decrease the amount of FP you are going to install, or how you are going to install over 3 floors. As a matter of interest what would you be installing her...?
