In my opinion, only the sprinkler(s) protecting the balcony in question needs to be calculated. 13R is quiet on this subject, but if you look at
*7.2.5 The number of design sprinklers for a corridor or breezeway outside the dwelling unit shall include up to the four most hydraulically demanding adjacent sprinklers. * I would consider a corridor or breezeway a much more challenging fire that affects the life safety of the occupants more than a balcony. As long as the multiply balconies are not attached to each other, the gap will allow the heat to be vented to atmosphere.
