I believe you still must use residential sprinklers IF it is residential. I do not know of any listed for dry use. You may have to cover the pipe and use listed attic sprinklers to protect any CPVC and the like, and run it wet.

My main question - does the time delay compromise the life safety of the elderly housing residential occupants?

If 13 is specified, that may be the reason why. I have seen and done it in nursing homes. Also you will see this in 4 story and under hotel/motels depending on owner. R/ Matt Matthew J.

Can a large dry system installed in an attic with the usual time delays of water delivered to the end head compromise the life safety aspect of the sprinkler system? The attic has 2 large air handlers with gas fired heating + AC and is fully sprinklered but considered unheated. It is just 2 stories and 13R could be used but 13 is specified. Is the dry system acceptable for life safety?
