Patent attributes
A fast response residential sprinkler assembly includes a sprinkler body having a base and a frame extending from the base. The base has a passage extending therethrough defining an inlet and an outlet. A deflector is mounted to the frame and spaced from the outlet, which is configured to deflect fluid flowing from the outlet in a radial pattern. A trigger assembly extends between the frame and the base and is adapted to seal the outlet and release the seal when a temperature associated with a fire condition is detected. In addition, the sprinkler body is configured such that a ratio of the flow in gallons per minute from the outlet divided by the square root of the pressure in pounds per square inch gauge of the fluid supplied to the inlet is in a range of 4 to 6.
