Abstract
Wet fire protection systems and methods for the protection of a stored commodity are provided. The system includes a supply portion coupled to a water supply and a demand portion including a plurality of sprinklers disposed above the commodity with each sprinkler having an operating pressure range. The plurality of sprinklers are interconnected by a network of pipes filled with water to provide each sprinkler with an initial pressure of water. A pressure control assembly is disposed between the supply portion and the demand portion to withhold fluid pressure from the supply portion from pressurizing the demand portion for a predetermined withholding period following actuation of at least one sprinkler in response to a fire.
