We had this condition about 10 years ago at the San Diego Airport, where the baggage conveyors pass though the separation between the exterior tug bays and the building interior. We positioned a QR sprinkler over the opening on both sides, and it was in accordance with an FM loss prevention bulletin. Can't remember which one, of course, but we provided this to the AHJ's (Federal and Local) and they all bought off on it.

However, this opening is for a conveyor to pass through. I don't think I can get a shutter there.

I have a 3' opening in a 3 hour wall and the architect is trying to see if this can be accomplished with a water or deluge curtain.
