Prior to my arrival, my company designed a group B building with a 300 foot long corridor which had a "slot" atrium. The floor opening consisted of a 3 foot wide slot that ran the entire length along the outside wall. The code consultant recommended a deluge system the entire length of the slot. The architects loved this idea. As a result they will occasionally suggest this as an alternative solution to some scheme they have in their brains at which point I voice loudly how this is the dumbest hair brained idea I had ever seen and the company is very lucky it has not released. Fortunately it was multi-zoned and provided with multiple interlocks.

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.
