An upright ESFR sprinkler includes a generally tubular body, at least one frame arm, a closure assembly, an unactuated heat responsive trigger assembly and a deflector assembly with a K-factor greater than 14, and preferably 16.8. The passageway extends between inlet and outlet openings. The closure assembly is positioned proximate the outlet so as to occlude the passageway with a Belleville seal. An ejection spring is coupled to the closure assembly. The heat responsive trigger assembly has a Response Time Index of 40 meter-second(msec) or less. The deflector assembly includes a nosepiece and a plate like redirecting member. The plate like redirecting member faces the outlet and is coupled to the at least one frame arm and spaced from the outlet opening. The plate shaped member includes a first generally planar portion, a conical second portion, and a third portion extending from the conical second portion. The third portion includes a plurality of tines and a plurality of slots with at least one slot disposed between every two tines so that, when the heat responsive trigger assembly is actuated and the closure assembly is positioned to allow a density of water to flow from the outlet of the body so as to suppress a fire of a particular commodity situated beneath the ceiling of 35 feet or less. System and methods relating to the upright sprinklers are also provided.

Upright, early suppression fast response sprinkler

A residential sidewall sprinkler and system for a coverage area defined by a pair of parallel vertical walls. The sprinkler includes a body having a passageway defining a K-factor of about 6. The body has an inlet coupled to a fluid supply line and a distal end coupled to a deflector assembly. The deflector assembly includes a face portion with an upper canopy and a lower canopy disposed about the face portion. The sprinkler is mounted to one of the walls to define a ceiling-to-deflector distance ranging from about four inches to about twelve inches. The fluid supply at the inlet is at least at one of a substantially constant flow rate of fluid and substantially constant fluid pressure. The deflector assembly distributes the fluid over the coverage area so as to wet the vertical walls within about twenty-eight inches of the ceiling over the ceiling-to-deflector range.

System and methods relating to the upright sprinklers are also provided.

A low pressure, extended coverage, fire protection sprinkler, e.g., of the upright type, suitable for use in protection of at least extra hazard and high piled storage occupancies, in accordance with the 1999 Edition of NFPA 13, has a body with an internal passageway extending between an inlet end and an opposite outlet end, and a deflector mounted to the body by at least one support arm and disposed in alignment with the axis and generally spaced from the outlet end of the internal passageway. The sprinkler has a predetermined K-factor, e.g., of greater than about 16.0. The sprinkler is configured and arranged to deflect flow of water generally radially outwardly and downwardly of the sprinkler in a predetermined spray pattern. Preferably, the predetermined spray pattern has a generally polygonal shape, e.g., a rectangular shape, when viewed at a predetermined distance below the deflector.

Upright, suppression sprinkler

An early suppression fast response pendent-type fire protection sprinkler is suitable for use in accordance with one or more of NFPA 13, NFPA 231 and NFPA 231C to protect single row rack storage, double row rack storage and multiple row rack storage, the sprinkler having a K-factor of about 25 and flowing pressure of about 15 pounds per square inch. Preferably, the sprinkler has a body defining an orifice and an outlet for delivering a flow of fluid from a source, and a deflector mounted with a first surface opposed to flow of fluid from the outlet. The deflector defines at least one pair of generally opposed reentrant slots extending from the first surface through the deflector, the reentrant slots extending from slot openings at an outer peripheral edge of the deflector inwardly from the peripheral edge toward a deflector axis.
