Reza, What Ron said is good. I would also say that if you use NFPA standards, you will get a system that works. A lot of what is in them has come from research or forensic analysis so there is a track record. Stick with a design based on NFPA 13, 14, 20, 22, 24 and whatever else is appropriate. Keep in mind, these are standards, not codes.
Best of luck.
