I'm currently working on designing wet sprinkler system for a Dormitory of Ground and First Floor "Light Hazard Occupancy". The Building is fully sprinklered as per NFPA 13R-2016. The height of the First Floor is less than 30 ft. Is it required to have Class II Standpipe inside? If required, which standard tells that "i.e. IBC, NFPA-14 .... "?
