ABSTRACT:
A horizontal dry fire protection sprinkler includes a housing having a vertical segment and a horizontal segment extending generally perpendicular to the vertical segment. The vertical segment defines an inlet opening. A plug member is disposed in the inlet opening for sealingly closing the inlet opening. A sprinkler is attached to the horizontal segment and includes a base having a passage extending therethrough and defining an outlet opening. A cap is disposed in the outlet opening and a heat sensitive trigger engages the cap. A translation mechanism is disposed in the housing and engaging the cap and supporting the plug member in the inlet opening, wherein when the heat sensitive trigger releases support of the cap, the translation mechanism is allowed to move within said housing to allow the plug member to dislodge from the inlet opening.
