FM and xl gaps requires isolation valves and it's a good operationally practice because someone will break a head or line

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.

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.

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 James Crawford Phaser Fire Protection Ltd.
