To determine “Minimum Water Supply Requirement” for areas of coverage where length and width of actual sprinkler spacing are not equal, select the “Maximum Sprinkler
Spacing” from the chart that is equal to or greater than the larger of the actual spacing (length or width) dimensions used. Example: When using 10’-6” x 13’-0” sprinkler spacing,
provide the “Minimum Water Supply Requirement” listed in the chart for 14’-0” x 14’-0” spacing. For areas of coverage smaller than shown, use the “Minimum Water Supply
Requirement” in the appropriate hazard group for the next larger area listed. The distance from sprinklers to walls shall not exceed one-half the “Maximum Sprinkler Spacing”
listed for the “Minimum Water Supply Requirement” used.
