AThe protected area refers to the area below the ceiling. The ambient temperature Is the temperature at the discharge end of the sprinkler. For protected area temperatures that occur between the values listed, use the next cooler temperature. xxThe minimum required barrel length Is not the same as the 'A' dimension. Refer to Figures 3-5 for the 'A' dimension. NDTE; Exposed minimum barrel lengths are Inclusive up to 30 mph wind velocities.
