Ralphy: I'm not sure I agree with your final sentence, "If for some reason the local ammendments require sprinkling of 13R attics or some other area which 13R specifically omits them from you would have to comply with 13 since it's outside the scope of 13R." I'm away from my office and don't have the new building code in front of me, but the previous edition (and presumably the current one) contains provisions for the use of sprinklers in attics in lieu of draft-stopping or compartmentalization requirements. It is absolutely possible to do a 13R system with a sprinklered attic per the building code; you would simply design the attic per 13 (light hazard, sprinkler spacing and positioning criteria for the type of construction) as it's an area outside the dwelling units. But the design would still be per 13R.

"Location of Sprinklers" (2007 ed) is in section 6.9 and is not in the section pertaining to areas within the dwelling unit (section 6.8.1) or areas outside the dwelling unit (6.8.2) it pertains to the whole standard; inside or outside the dwelling units unless noted otherwise. 13R never directs you to 13 for that criteria. If for some reason the local ammendments require sprinkling of 13R attics or some other area which 13R specifically omits them from you would have to comply with 13 since it's outside the scope of 13R. I know you probably already know this - I'm just clarifying my self if I didn't make sense earlier.

The relative hazard is not based upon the bathroom being within a dwelling unit and the area outside the dwelling unit is NOT a 13 system but still a 13R with discharge criteria based on 13. Insert caveat about this is not to be considered a formal interpretation fo NFPA or any of its technical committees.
