Notes:
1. For NFPA 13 installations the ow per sprinkler must be the greater of: (1) the ow listed in Table E above and (2) the ow required to achieve a minimum
design density of 0.1 gpm/sq ft over the design area of the sprinkler.
2. For coverage area dimensions less than those listed above, use the minimum required ow for the next larger max. coverage area listed.
