NFPA 13-2013 art.8.17.5.2.1 mentions: In buildings of light or ordinary hazard occupancy, 21⁄2 in. hose valves for fire department use shall be permitted to be attached to wet pipe sprinkler system risers.
1- Is it acceptable to attach a pipe to a class I standpipe riser in a stairwell to feed an outside sprinkler room. The room would include three wet pipe sprinkler systems with alarm check valves and individual control valves. 2- Is it acceptable to have an auxiliary dry pipe sprinkler valve fed by a combination standpipe/sprinkler riser? 3- Is it acceptable to have a storage occupancy protected by sprinklers from a combination standpipe/sprinkler riser?
