There are many sprinkler calculation programs available, none of them free if they are worth using.
FM-200 system calculations cannot come from the manufacturer of the agent, Dupont.
The agent flow through the cylinder dip tube, discharge valve, and ultimately discharge nozzles is specific to each equipment manufacturer. All use different valves, nozzles etc. This presents a different hydraulic profile for each. Therefore each manufacturer has a proprietary software package and no generic is available.
You will only get your hands on this software if you can:
1. Prove to one of the manufacturers that you are qualified to use the software. This proof can come in the form of previous experience, NICET Certification, etc.
2. Obtain a distributorship. This will also require the satisfaction of (1.) above.
