Question from another board:::
To get to the point I cannot find any reference in NFPA 13R regarding system area limitation. Normally I would insist, based on NFPA 13 that a floor that is over 52,000 SQ.FT requires 2 risers, but this is an existing building where the other floors, all roughly over 71,000 SQ.FT., are already being supplied by one riser. I was about to yell foul, but figured I'd get all my info straight first, unfortunately I cannot find anything in NFPA 13R that says they cannot do so.
and the answer is::::::::
