He's probably citing paragraph 11.2.3.1.3 from NFPA 13, 2002 "11.2.3.1.3 An allowance for inside and outside hose shall not be required where tanks supply sprinklers only."

I am reviewing an ESFR design for Group A plastics to 17 ft in a building with a nominal height of 20 ft. Because the sprinkler protection for this building is supplied by a dedicated tank and fire pump arrangement, the designer omitted the inside/outside hose allowances. Now, I recognize that doing this is permitted for a number of configurations. In fact, this would be permitted for the design I reference above if the protection were of the "occupancy hazard fire control" type as stated in NFPA (2002) 12.3.3.1.11.1 Yet in the ESFR and large drop protection schemes for this commodity configuration that follow the above referenced section, there is no mention of a similar exemption clause. In being silent on the issue, I can only conclude that NFPA 13 intentionally does not provide such an exemption and that a hose stream allowance is required regardless of supply. My questions to you all is: Am I missing something?
