Abstract
Ceiling only dry sprinkler systems and methods for protection of a storage occupancy employing a mandatory fluid delivery delay period. The systems and methods provide for fire protection of stored commodities of forty-five feet or greater with a hydraulic design ranging from six to eighteen design sprinklers. The systems and methods employ an upright sprinkler having a nominal K-factor greater than 28.

A fire protection system, comprising:
- a plurality of sprinklers beneath a ceiling of a storage occupancy, the plurality of sprinklers having a sprinkler-to-sprinkler spacing greater than or equal to six-by-six feet and less than or equal to twenty-by-twenty feet, the plurality of sprinklers arranged in a hydraulic design area of greater than or equal to six and less than or equal to eighteen sprinklers,
- each sprinkler of the plurality of sprinklers having a K-factor greater than or equal to 11 gpm/(psi)1/2 and less than or equal to 36 gpm/(psi)1/2,
- each sprinkler of the plurality of sprinklers having a deflector shape outputting fluid in a spray pattern having a non-circular shape in a plane below the deflector and perpendicular to an axis through the sprinkler, the non-circular shape comprising a central area and an outer area outward from the central area to a periphery of the non-circular shape, the central area having greater fluid distribution than the outer area.
A fire protection system, comprising:
- a plurality of sprinklers beneath a ceiling of a storage occupancy, the plurality of sprinklers having a sprinkler-to-sprinkler-spacing greater than or equal to six-by-six feet and less than or equal to twenty-by-twenty feet, the plurality of sprinklers in a design area of greater than or equal to six sprinklers and less than or equal to eighteen sprinklers,
- each sprinkler of the plurality of sprinklers having a K-factor greater than or equal to 11 gpm/(psi)1/2 and less than or equal to 36 gpm/(psi)1/2,
- each sprinkler of the plurality of sprinklers having a deflector shape outputting fluid in a spray pattern having a non-circular shape in a plane below the deflector and perpendicular to an axis through the sprinkler, the non-circular shape comprising a plurality of areas from a center area to a perimeter, an amount of the outputted fluid being less towards the perimeter than in the center area.
