ABSTRACT An economical fire protection system specifically designed for rural unheated buildings. The system features a direct burial water storage vessel that is pressurized by a non-combustible gas. Unlike conventional sprinkler systems, the expense of providing heat to the structure or the use of large quantities of anti-freeze or heavy electrical requirements are eliminated. Burying the water storage vessel below the frost line protects the fire-fighting water from freezing. The use of a check valve interposed between the water storage vessel and the piping connecting the sprinkler heads enables the remaining part of the system to be dry in the readied state. In an alternative embodiment, this piping can be filled with a non-freezable liquid to prevent freezing. Due to the small volume, the amount of anti-freeze required is minimal. The system also features a comprehensive alarm system to warn of system failure or to announce a fire.
