Indeed Travis and I have journeyed down this road before, one time in
particular.
An AHJ, who happened to be a registered PE, AND the state fire marshal
was insisting that Travis' design would not be accepted using CCS
sprinklers, and that standard spray QR's be used, even though that use
was contrary to -13, and their listing.
If I remember the remarks of the AHJ correctly, when politely - VERY
politely - challenged by Travis, his response was, "Just do what I tell
you, that would make it so much more simple."
some times I just shake my head,

It says specifically listed. That means you must use specifically listed
sprinklers. How deep is the space? Is it flat or sloped? If it meets the
criteria for the specially listed, then that is what you use. Ive been down
this road many times.

My question is: Are QR uprights listed to be used in those areas or does it
have to be a CCS sprinkler?

Troy,
No. NFPA 13, 2019 edition in 9.3.2 is specific that sprinklers are listed
for horizontal combustible concealed spaces. Specifically listed to provide
protection.....

Can someone confirm that it is not mandatory to use CCS sprinklers in
a space 36" or less?
I know it allows for larger spacing, but code wise. I don't believe
they are a must and the space can be protected with QR uprights.
