16.3.1.1 is CMDA sprinklers, not CMSA, unless I am mis-reading your
references. CMDA would just have the 30% increase in the system design
area.
Table 16.3.2.1 (NFPA 13 2013 edition) is the CMSA section. That
includes criteria for a dry pipe system. I am assuming you are able to
use the dry system criteria for your preaction system.

Hey everyone, I am looking at a freezer project, 30' storage 33' building
height, class II, unencapsulated stored palletized on open shelves. Does NFPA
13 2013 chapter 16 place any restrictions on the use of a pre-action system for
this type of configuration? Specifically I am looking at 16.3.1.1, CMSA with
one level of in rack, per 16.3.1.1, figure e, or f.
Thanks for your input,
