Abstract

A sprinkler having a design such that they can be arrayed where the coverage of each exceeds 80 square feet - preferably less than 200 square feet in extra hazard or high piled storage environments up to ceiling heights of 25 feet or greater, including ceiling heights of approximately 30 feet or greater and being adapted to control through the maintenance of the heat release rate for the prescribed period of time established by NFPA- 13 standards for what are termed 'Extra Hazard' and 'High Piled Storage' occupancy in which sprinklers preferably having a K factor of 18-40 through the selective combination of pressure and trigger-speed provide sufficiently large drops of water to permit the same to maintain sufficient size and density after contacting the structural members generally encountered in warehouse-type facilities to be able to penetrate the fire plume. Specifically, in its preferred embodiment if the pressure is 7-10 psi, a diagonal line emanating from the center of the deflector to the edge of the obstruction (A) is greater than 3 times the height or 3 times the width of the obstruction.
