See NFPA 14, 2007 7.3.2 (5) and A.7.3.2(5) Also its always best to check
with the AHJ for any standpipe installation since they are the end user, and
may have their own policy on how there are used as part of their "Fire
Attack Plan"

Subject: Roof manifolds
The buildings in the area in which I live rarely, if ever, are more than
three stories high, so my experience and knowledge of standpipes is limited
to the contents of NFPA14 and that is the source of my question. I have a
four story motel with two standpipes with a combined system. I must install
a roof manifold per code but I’m not sure if it should be one off each
standpipe. I would say yes because the standpipe pipe is sized by the
required hydraulic calculation procedure which utilizes both standpipes
which share the required flow, so if there is only one roof manifold at the
remote standpipe then the total flow could require larger pipe which in turn
would make the initial calc procedure null and void. How many roof manifolds
should I install?
Any suggestions will be greatly appreciated,
Ron
