The EC sprinklers are listed at a specific density, so you can't change that. You can calculate 2000 sq ft, but it will still be the minimum flow / pressure at a given spacing per the data sheet. Also, they are not listed for storage. So, they can not be used for storage applications.

I have a customer that wants to store non-encapsulated ,Class II on single/double row racks with 8ft aisles. to 15ft high. When I work out the numbers and apply Fig 16.2.1.3.4.1 (NFPA 13, 2013ed) I get a density of 0.189/2000 for high temperature sprinklers. The original system was designed using extended coverage K14 sprinklers, 18x18 at OH 2 density. If I go up the OH2 curve to 2000 sq ft I get a 0.19/2000 density. Can I pick up the additional EC sprinklers for the 2000 sq ft at the required EHP for the OH 2 spacing and call it good if the calcs work?
