You might want to look at FM Data Sheet 1-23. They have scheme for protection of wall openings via water spray nozzles protecting both sides of the wall, using separate deluge systems.

The protection we finally decided on was a small deluge system with heat detectors on both sides of the wall. The heat detectors could be mounted at the ceiling where the heat would gather.

The openings cannot realistically be closed, so they are asking about a water curtain. I have a couple of questions: First, NFPA 13 discusses water curtains around vertical openings but not horizontal, from what i found. Am i missing something? Second, the ceiling is approximately 12 ft above the top of the openings. The sprinklers need to be 12" from the deck max. Will that vertical distance create an issue with the water curtain performance.
