yeah. These are not full draft stops by any means. It is just
something that the architect misses on just about every job I have had
these heads, and then the GC either has eat it, or get an extra from the
owner to put in something the arch missed. It just leads to a battle.
It is good when you have the option to let the GC know upfront that
these are req'd, but that is not the case on every project.

Like Marriott's requirement to use NFPA 13, not 13R?
Draft STOPs aren't required, can be curtains of plywood coming down 8" or 1/3
the depth. Take a look at the Tyco catalog data on CC1 and CC2 sprinklers- explains
it all nicely.

Do you have the 2009 IBC available? You're installing a 13R system? Would
sprinkler protection be necessary in the attic space? If NFPA 13R and no
sprinklers in the attic, then 3,000 sq ft draftstopping is needed. This would
definitely be the architect's job to show these in my opinion. If no
draftstopping is in the job, then your sprinkler scope extends to the attic.
If you must use a specially listed head for this purpose and if this head
requires 1000 sq ft draftstopping then it seems better to add the 3000 sq ft
draftstopping (or two units) and omit the sprinklers.
Have I interpreted this correctly, aside from any Marriott special requirements?

Looking for some other forum experience here. How have you been dealing with
architects and GC's that state the IBC does not require draft stops in an
attic, so they are not willing to put them in when the CC heads are req'd and
the CC heads require a draft curtain to be installed?

I agree. Just looked at that this morning. The handbook elaborates
that
testing has found standard sprinks to be ineffective in short flat comb

Trying to settle a "discussion" here. When you have a flat concealed
combustible space and<36" of clearance, are the specially listed heads
required?
