1. A fire protection system, comprising:
a plurality of sprinklers, each sprinkler of the plurality of sprinklers comprising an early suppression fast response (ESFR) frame body, each sprinkler of the plurality of sprinklers installed beneath a ceiling of a storage occupancy, the storage occupancy having a stored commodity having a storage height less than or equal to 60 feet, the ceiling and the plurality of sprinklers above the stored commodity, the storage occupancy having a ceiling height less than or equal to 60 feet;
each sprinkler of the plurality of sprinklers has a K-factor in GPM/PSI1/2 greater than or equal to 14.0 and less than or equal to 33.6, the ESFR frame body of each sprinkler of the plurality of sprinklers having an inlet, an outlet, and an internal passageway extending between the inlet and the outlet; and
a network of pipes coupled with the plurality of sprinklers, the network of pipes provides a minimum operating pressure of fluid to the plurality of sprinklers, the network of pipes comprises a hydraulic design area including less than 12 hydraulically remote sprinklers of the plurality of sprinklers.
