I think he is saying that his concealed space is >36" in depth. If so,
then specially listed are not mandated.
If so, I have always used the QR reduction for 10' ceiling height in
those spaces provided it is a wet system. I have had some AHJs require
I go to the floor to get my deck height. So, if you were 14' floor to
floor with a 10' ceiling and 24" open web floor trusses, then you could
use QR SSU to protect. A conservative approach would be to go with 14'
for your QR reduction point.

Taylor,
I believe you will need to use Concealed Space Sprinklers for that
area and will need to calc based on the manf data sheet.

*Subject:* Combustible Concealed Space-Area Reduction
Good afternoon forum,
I’m looking to apply the remote area reduction per 11.2.3.2.3.1 in
NFPA 13 2010 to a floor truss space over 36” using quick response,
standard spray sprinklers.
Could anyone tell me if my assumptions are right?
