I'm working on a project with a foam-water sprinkler system using NFPA 16 Section A.5.4.2 as a guide.
There are four rooms with different dimensions that need to be protected and we have a deluge valve on each room. My client wants to have a single proportioner for the four rooms.
Can I achieve the 3% concentration in each room even though the orifice is size based on the largest room?
Or do I have to provide a proportioner for each room to be able to achieve the 3% upon discharge on any room?
Any guidance here is much appreciated.
