SSU are not specifically listed for CC spaces less than 36" in depth. They are listed for CC spaces though. Which is what drove the manufacturers to produce the "CC" heads.

You have TJI's, so you don't have to use them - use standard-spray QR heads. Is that crazy? Yea, but that's the way it's written. The commentary in the handbook gives supports to the above.
