Tony, I only do a calc to prove the # of heads on the balcony and do not pick up any heads inside the unit. I use 200F QR sprinklers and if I cannot use dry type then I run a small A/F system to supply the heads. This way I can keep the pipe CPVC and not worry about a pitch issue. If the AHJ has a problem with multiple floors / balconies being on one zone then the best option I see is to use the dry try sprinklers fed from each floor and have a bulk head created if necessary.

My approach was, I considered the balcony as a normal room. So I designed the balcony head and three additional residential heads from the living room, which was the communicating space. So four sprinklers in total. Running piping to a dry sidewall from the suite side is generally a problem, as the floor levels are different and the architects don't want to provide bulkheads or soffits. For a few projects now I have designed a dry pipe system for the balcony heads. Usually there is a corner fireplace at the exterior wall. Run a vertical pipe behind the fireplace and supply the head in the balcony. Horizontal piping run in the basement parkade. The only problem is zoning, as the building code requires each floor zoned separate. My opinion is having a single zone (or several depending on floor area) for the balconies can't really hurt. Anyway, up to now, no objections. Then again, it could be that no one checks my designs that close. Has anyone else designed this way?
