We have a series of highrise buildings where an NFPA 13 sprinkler system and a wet standpipe system (NFPA 14) are to be installed.
If the sprinkler and the standpipe systems are supplied by a common fire pump, and horizontal supply pipe, but have separate vertical risers, will the system be considered a combined system?
Will the subsection of NFPA 14 (2019 Edition) section 188.8.131.52.1.1 apply?
184.108.40.206.1.1 In a building protected in accordance with NFPA 13 or NFPA 13R, the water supply for the combined sprinkler and automatic standpipe system shall be based on the sprinkler system demand (including any hose stream demand) or the standpipe demand, whichever is greater.
The buildings are fully-sprinklered, and the proposed fire pump is rated at 1,000 gpm. There is a water storage tank of 30,000 gallons. Thanks in advance.
