1-1/2" & 2-1/2" Hose Connections

Can someone confirm for me that the hose connections talked about in 8.17.5.1.3 are the Small (1-1/2") type only? If so what are acceptable supply points for 2-1/2" hose connections? Brian Harris First Defense Fire Protection 11957 Ramah Church Road Huntersville, NC 28

Remote Area

obby, the Lobby itself is 1200 sq.ft. Can I do a calc on just the Lobby or do I need to pick up an additional 300 sq.ft. from the first floor? I was always taught you could just calc that entire area but now I'm starting to wonder. Brian Harris First Defense Fire Protection 119
