Abstract: A sprinkler system includes a fitting, at least one tube, at least one fluid distribution device, and an actuator. The fitting connects with at least one pipe, defines an opening, and includes a seal. The seal has a closed state in which the seal seals the opening and an open state in which the seal does not seal the opening to allow fluid flow from the at least one pipe through the opening. The at least one tube connects with the fitting on an opposite side of the seal from the at least one pipe. The fluid distribution device is connected with the at least one tube. The actuator receives a detection signal indicative of a trigger condition and causes the seal to change from the closed state to the open state to allow the fluid flow through the opening responsive to receiving the detection signal.

Abstract: A dry sidewall sprinkler and system and methods of installation provide extended coverage for ordinary hazard commodities. The preferred sprinkler and systems provide for sidewall ordinary hazard fire protection beneath a sloped or horizontal overhang extending from a structure by at least ten feet proximate to a garage or loading dock in accordance with applicable sections of NFPA-13 (2007).

Abstract: A dry sprinkler installation and sealing device for a cold environment is disclosed. The dry sprinkler installation includes a supply conduit having a first end adapted to communicate with a fire retardant fluid source and a second end supporting a sprinkler head. The supply conduit is dimensioned to extend through an opening in a wall of a cold environment, e.g., a freezer ceiling. A flexible sealing device is positioned about the supply conduit adjacent an exterior surface of the cold environment. A first end of the sealing device is secured about the supply conduit and a second end of the sealing device is secured to an exterior surface of the cold environment. The flexible sealing device allows for radial and axial adjustments to the supply conduit and sprinkler head without comprising the integrity of the sealing device.
