Hydraulic Criteria for Single Slope With FL-SA/DS Sprinklers Wet System Only
When a single slope roof area exists, the following calculation procedures shall be followed to size piping to the
sprinklers protecting this area. NOTE: Single Slopes (with vertical shear walls) result in different fire dynamics than
might be seen with gable and/or hip roof construction.
1 Row Protection
• Calculate the most hydraulically demanding 5 contiguous DS sprinklers. See Figure 24A.
• Minimum sprinkler flow is 20 gpm per sprinkler.
2 Row Protection
The following 2 sets of calculations shall be performed:
• Calculation #1: Calculate the most hydraulically demanding 5 contiguous sprinklers consisting of 3 at the high
point and 2 on the adjacent slope. See Figure 24B.
• Calculation #2: Calculate the most hydraulically demanding 5 contiguous sprinklers along the high point. See
Figure 24C.
• Minimum sprinkler flow is 20 gpm per sprinkler.
