Abstract
Fire protection system and methods for concealed spaces providing for effective fire protection over an effective depth range measuring from a minimum six inches up to a maximum that is greater than thirty-six inches. A combustible concealed space that includes an upper deck and a ceiling deck spaced about a longitudinal axis extending substantially parallel to the ceiling deck with a fire protection system having a firefighting fluid supply pipe and at least one automatic upright sprinkler coupled to the fluid supply pipe and positioned to define an effective depth range that measures from six inches to a maximum of at least sixty inches.
Claims26
A fire protection system for protection of a combustible concealed space having an upper deck and a ceiling deck spaced about a longitudinal axis extending parallel to the ceiling deck defining an effective depth range between the upper deck and the ceiling deck in a direction perpendicular to the longitudinal axis, the effective depth range greater than six inches and not to exceed eighty-four inches, the system comprising:
- a firefighting fluid supply pipe having a parallel portion relative to the longitudinal axis;
- and
- at least one automatic upright sprinkler coupled to the firefighting fluid supply pipe within the combustible concealed space, the at least one automatic upright sprinkler having a coverage area greater than or equal to 144 square feet and less than or equal to 256 square feet with a design density over the combustible concealed space of at least 0.1 gpm/sq. ft., and including:
- a frame body having an inlet for receipt of a firefighting fluid, an outlet with a passageway extending between the inlet and the outlet to define a discharge coefficient of a nominal K-Factor, wherein the passageway and the outlet of the at least one automatic upright sprinkler defines a nominal K-Factor of 5.6K with a sprinkler-to-sprinkler spacing ranging from 8 feet to 16 feet,
- a seal assembly,
- a thermally responsive glass bulb having a temperature rating of 200 degrees Fahrenheit to support the seal assembly in the outlet;
- and
- a deflector coupled to the frame body and spaced from the outlet for distribution of the firefighting fluid.
A method of for protecting a combustible concealed space comprising:
- obtaining a fire protection system comprising:
- a firefighting fluid supply pipe having a parallel portion,
- at least one automatic upright sprinkler coupled to the firefighting fluid supply pipe within the combustible concealed space, the at least one automatic upright sprinkler having a coverage area greater than or equal to 144 square feet and less than or equal to 256 square feet with a design density over the combustible concealed space of at least 0.1 gpm/sq. ft., and including:
- a frame body having an inlet for receipt of a firefighting fluid, an outlet with a passageway extending between the inlet and the outlet to define a discharge coefficient of a nominal K-Factor, wherein the passageway and the outlet of the at least one automatic upright sprinkler defines a nominal K-Factor of 5.6K with a sprinkler-to-sprinkler spacing ranging from 8 feet to 16 feet,
- a seal assembly,
- a thermally responsive glass bulb having a temperature rating of 200 degrees Fahrenheit to support the seal assembly in the outlet, and
- a deflector coupled to the frame body and spaced from the outlet for distribution of the firefighting fluid;
- and
- distributing the fire protection system for installation in the combustible concealed space having an upper deck and a ceiling deck spaced about a longitudinal axis extending parallel to the ceiling deck defining an effective depth range between the upper deck and the ceiling deck in a direction perpendicular to the longitudinal axis, the effective depth range greater than six inches and not to exceed eighty-four inches, wherein the parallel portion of the firefighting fluid supply pipe is parallel relative to the longitudinal axis.
