In my former community, in the DC area, we had a regular water-based ("wet") system for the building interior and a pressurized-air ("dry") system for the shelter on the roof since those pipes are open to the elements and water would be subject to freezing. A dry system works by storing compressed air in the exposed pipes. When a sprinkler head is activated, the air is released from the pipe, which opens a valve and allows water to flow from sheltered interior pipes to the sprinkler head. I was interested in your question because I hadn't heard of antifreeze-based systems before. I figured you must live in a very cold climate. The DC area doesn't get *that* cold, or not for long periods of time. Maybe dry systems aren't suitable for very cold areas like Michigan. Our dry system was super-fussy. It was responsible for almost all of the false fire alarms we had in the several years after move-in. (I can't speak to current performance.) In hindsight, I think I would have welcomed an antifreeze-based wet system as an alternative. I'm happy to chat offline. I learned a lot about the system and in fact wrote up some operation and maintenance instructions that I would be happy to share if I can dig them up.
