To determine "Minimum Water Supply Requirement" for areas of coverage where length and width of actual sprinkler spacing are not equal, select
5
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 ft 6 in x 13 ft (3.2 m x 4 m) sprinkler spacing, provide the "Minimum Water Supply Requirement" listed in the chart for 14 ft x
14 ft (4.3 m x 4.3 m) 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.
For Sprinkler VK572 with High Temperature 286 °F rating, UL restricts the QR listing to their use in Ordinary Hazard occupancies to the high temperature
6
zones within a building only. VK572 quick response sprinklers with this temperature rating cannot be used throughout the property.
Accepted for use, City of New York Department of Buildings, MEA Number 89-92-E, Vol. 38.
