Sprinklers !!

[slimwilly]

I have a house that requires them in the kitchen and front room as they serve as the only exit in the house,
I am looking for info on installing them,suppliers etc,
I am told that the firms are very expensive to install them,so is was wondering if anyone could give me info as to the requirements needed for a legal system,
I already have suspended ceilings with plumbing in them so concealment of pipework no problem.
I am a plumbing and heating engineer so hoped i could install myself.


Any info gratefully accepted.
