NFPA 13, 2013 Chapter 8 in a nut shell, ALL areas of a building shall be protected unless specifically omitted by NFPA 13 Coolers and Freezers do not have an exception or exclusion anywhere in the code to allow sprinklers to be omitted in them If you have the handbook there is more discussion in detail about this that specifically talks about coolers and freezers having no exclusions from protection, or the annex - A8.1.1 I believe the fire code refers to NFPA 13 for all sprinkler related codes.
