I'm doing one right now with a 3:12 I inquired with our very experienced foam FPE and he said no increase. Now we didn't get fully into it but in a nut shell there is no requirement. 13 is not used. My thinking is the sprinklers are a water based heat detection system. The HEF is what will control the fire or not. Also I just learned HEF has never been tested for this application.
