While I am not a fire suppression engineer, nor do I play one on TV, although there was this little acting troupe I was in, did a lumberjack skit...oh wait, wrong forum. I have the National Fire Protection Association (governing body for this stuff) standards for water suppression. I could look up the basic requirements. It would need to be a wet pipe system (always filled with water) unless you wanted to install the fire pump. I don't know how readily available the nozzle components are, but the rest is just piping, generally threaded, galvanized pipe. The only issue I see is that you would probably want to/have to remove it if you sold your house. These systems also take alot of water. You may want to hook up 3-4 sprinklers on short hoses and see what your water pressure can accomplish in terms of volume.
