The note at the bottom of Table 508.4 states: S = Buildings equipped throughout with an automatic sprinkler system installed in accordance with Section 903.3.1.1.
903.3.1.1 NFPA 13 sprinkler systems. Where the provisions of this code require that a building or portion thereof be equipped throughout with an automatic sprinkler system in accordance with this section, sprinklers shall be installed throughout in accordance with NFPA 13 except as provided in Section 903.3.1.1.1. Note, it does not reference 903.3.1.2 which is for NFPA 13R sprinkler systems.

I think there are 2 trade-offs including the reduction of the passive rating that is restricted to the presence of a full 13 system throughout BUT the IBC considers a building protected throughout even when a 13R system is installed. Awaiting input from our code boys and gals.
