dormitory sprinklers supplied over 3 floors
(OP)
HI!
I have a dormitory 3floor building which will be renovated. There will be interconnected housing-modules from 1st to 3rd floor. Means, that in 3rd & 2nd floor are 2 sleeping rooms in each floor (4 persons total) and in the 1st is a shared kitchen & living space. there will be 16 modules in the building.
can i supply 1 sprinklerriser for each module from the basement which supplies each floor of a module? Means, there will be 16 sprinklerrisers, 1 for each modul.
is it allowed as per nfpa to supply 3 floors from the basement? Each module has about 20 sprinkler in total. system is wet.
Thanks!!

RE: dormitory sprinklers supplied over 3 floors
Yes, as long as the total area of all floors combined does not exceed 52,000 sq ft in the case of Light or OH.
The way I read it is if there's a basement and each floor does not exceed 13,000 sq ft (52,000 total) you're fine.
I suppose if the third and fourth floor is each 50,000 sq ft you can combine the third and fourth (100,000 sq ft) with a single floor control valve controlling water to the third and fourth floor.
