And by the way-- say you have 3 skylights, 3' square, at 9' c-c, those skylights would need to be sprinklered, right? Wrong-- only the middle one needs a head, bcoz now the other 2 are separated by at least 10' from any other unprotected ceiling pocket! (2010 clarifies)

The recesses are required to be separated by at least 10 feet so any delay caused by the height of the pocket would not have an impact. The sprinkler handbook provides a good description of this condition. It references skylights or "similar pockets". Robert J.

If the answer is yes, any logical reasons one could offer would be helpful.
