Yes..QR reduction permitted. We take the height based on the distance
from the lowest ceiling to the peak. Remember to take the 30% increase
for sloped ceilings.
One thing to consider. You are going to be limited to 120 sq ft per
sprinkler. Consider using 4.2k SSU (light hazard wet pipe) as it will
greatly minimize the over-discharge and therefore friction losses in
your system.

Here's one for Y'all.
With a wet-pipe system in an attic, (4/12 pitch) can the area reduction for
quick response sprinklers be used?
If so, how is the ceiling height determined? From the ceiling below to the
highest point of the roof?
Thanks
Bill
