Section 8.4.5.1 permits residential sprinklers for dwelling units "and their adjoining corridors" and I think that's the key to get you into 11.3.1 for calculations. (2013 edition references).

In the NFPA 13 handbook, it says that when doing room design method, you can consider the corridor a room and calculate 5. However, the handbook goes on to state that you can’t use room design for residential sprinklers and you must calculate 4 sprinklers. This may require going to adjacent rooms if necessary. So, since we can’t use room design for the corridor and residential sprinklers, it would seem that you would only calculate 4. To eliminate the 75’ max argument, let’s say the sprinklers are spaced at 16’ on center. So, do we calculate 4 or 5 residential sprinklers in a corridor? This came up in a discussion today.
