Where does it say that the sprinkler system must be zoned the same
as the
alarm system? It only says the sprinkler system must be monitored.

My building code. Yours might be different. Further, it includes a
sprinkler
system as an alarm initiating device. So whatever zoning is required
of the
alarm system, the sprinkler system also must comply.

Where does the requirement to zone by floor come from?

If I'm not mistaken (And that happens more and more lately) the
"Zone by
Floor" is an alarm requirement, and could in theory be met by the
smoke
detectors. The balcony issue is unique, since they don't require smoke
detectors on the balcony. But since detection in multi-story
buildings is to
help the FD identify the source of the alarm/fire, I would think
that a
balcony, visible from the exterior would not compromise this.

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.

Subject: RE: 13r balconies
I just finished a design with balcony heads for a 13 residential
building.
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?
Tony

I think it would be a one head calc (assuming only one head per
balcony and
they are not contiguous), but it is 5 AM and no coffee yet.

I need a quick opinion from some 13R experts.
13r condo with the first floor divided in half front to back and
then
the front half is divided into 4 parking areas seperated by fire
walls. The front wall is completely open and each garage serves 2
units.
6.8.2.2 states that each compartment can nothave openings greater
than 50 sq.ft. I am interpreting this to mean openings into adjacent
compartments not to the atmosphere and therefore a 4 head calc would
be appropriate using dry heads flowing in accordance with NFPA 13R.
Thoughts please...
