Brian: We design AFSS for a LOT of schools projects but, since we're in California, my answer may be contaminated by state amendments to the building code. That said, the code in CA states that a Class III standpipe is required at each side of any stage greater than 1,000 sq. ft. in area. There's also an exception stating that if the building is fully sprinklered that at the designer's option either a small hose connection per NFPA 13 or a Class II or III standpipe connection per NFPA 14 may be installed. We find it's generally simpler and saves a separate piping complement if we call them small hose connections. So they're calculated as inside hose streams concurrent with the ordinary hazard design area of the stage itself, which is invariably the most demanding in theater arts and multi-purpose buildings on K-12 campuses. So add 50 gpm at each connection to the main that supplies the hose connections and stage sprinklers.

Do I add the 50 gal for each valve in every remote area calc or only the remote area for the stage calc's? Brian Harris, CET BVS Systems Inc.
