I am looking at Figure 25.3.2.4.1 (e) In Rack Sprinkler Arrangement and Design, Exposed Nonexpanded Group A Plastic Commodities Up to 25 ft. in Height in Up to a 35 ft, High Building. Option 2: .30 over 2,000 sq. ft. Notes (1) In-rack sprinklers are ordinary-temperature-rated, quick - or standard-response, pendant or upright, minimum K-5.6 (K-80), and designed for a minimum of 14 in rack sprinklers (seven in rack sprinklers on each level) operating at 30 gpm (114 L/min) when one level of in rack sprinklers is installed. Is this a typo? am I not understanding it correctly? Should it say 'when two levels of in rack sprinklers is installed.' or Should the GPM be different with two levels? Option number 1 is pretty straight forward -
Option 1: .80/1,500 sq. ft. Notes (1) In-rack sprinklers are ordinary-temperature-rated, quick - or standard-response, pendant or upright, minimum K-5.6 (K-80), and designed for a minimum of 8 in rack sprinklers operating at 30 gpm (114 L/min) when one level of in rack sprinklers is installed.
