Don't you want the racks separately controlled because they are
susceptible to physical damage. If you damage a rack sprinkler, you can
shut it off and keep the overhead active. In your case, if you need to
shut down the racks, you also shut down the adjacent overhead system.

Why is it zoned? Just because it's bigger than 52K? One big open
space? Not trying to be a smart ass (or maybe I am) but the FD won't
fight a fire in zone 2 that is happening in Zone 1 bec aide an
annunciation says here, not there, and it sounds like they'd be able
too see the fire on entry.

I just came from a building where the in-rack sprinklers are
connected into the adjacent roof system.
The building has two roof zones, north and south, the in-racks are
in the north zone but connected into the south zone (no control
valve at the connection point)
I have never ever thought of doing this as it would send two
different signals in the event of a fire, but cannot seem to find
anything that says you can’t do this, with the exception of alarm
signals.
Any comments on this arrangement?
Thank you
