Why not just use closed HSW's? It's so rare that most non-industrial facilities even have the water flow and pressure to sustain a deluge system unless it's real small.

Armstrong ceiling clouds that are arched, architect doesn't want to penetrate the clouds like the Armstrong data sheet shows so we have QR sprinklers above the clouds and a deluge system of sidewall sprinklers feed from the soffits throwing water under the clouds. Some big DA came up with this idea. It's a tiered classroom with a sloping floor, I suggested they install some life preservers for the students so they won't drown when the system trips.
