Abstract: An automatic dry fire protection sprinkler assembly and method of operation. The sprinkler assembly includes an elongate tubular outer housing having a fluid discharge end with an outlet opening, an internal channel and a contact surface proximate the outlet opening. A fluid deflection member is coupled to the housing at a preferably fixed distance from the outlet opening. An internal fluid control assembly includes an ejectable member that is ejected out the outlet opening and displaced out of the fluid flow path between the housing and the fluid deflection member. Upon sprinkler actuation, the fluid control assembly engages the internal channel to axially guide the fluid control assembly and prevent rotation of the fluid control assembly about the sprinkler axis. A surface contact between the ejectable member and the internal shelf causes the ejectable member to pivot clear of the sprinkler housing and the fluid deflection member.

Abstract: A dry fire protection sprinkler assembly. The sprinkler assembly includes an elongate tubular outer housing having a first end and a second end opposite the first end. The second end of the housing defines a fluid discharge end of the sprinkler assembly having an outlet opening. A fluid deflection member is affixed to the housing at a preferably fixed distance from the outlet opening. The sprinkler assembly and the fluid deflection member define an unencumbered fluid flow path for a column of fluid discharge from the outlet opening. The fluid deflection member includes at least one tab to act on the unencumbered column of fluid discharge.

Abstract: An automatic dry horizontal sidewall fire protection sprinkler assembly for residential fire protection. The sprinkler assembly includes an elongate tubular outer housing having a first end and a second end. The second end of the housing defines an outlet opening and an internal channel and contact surface proximate the outlet opening. A fluid deflection member is coupled to the housing at a fixed distance from the outlet opening. An internal fluid control assembly includes an ejectable member that is ejected out the outlet opening and displaced out of the fluid flow path between the housing and the fluid deflection member. The sprinkler assembly provides a plurality of coverage areas suitable for residential fire protection over a plurality of nominal operating temperatures up to 200° F.

A surface ontact between the ejectable member and the internal shelf causes the ejectable member to pivot clear of the sprinkler housing and the fluid deflection member.

Abstract: Concealment assemblies for fire protection sprinklers. The concealment assembly includes a cover member having an external surface with a base coating of uniformly applied polymer. One or more different polymer coatings are disposed in a discontinuous manner over the base polymer to provide a visual contrast and form desired indicia.
