Architect here. I think this sets in a different category than sprinkler systems. It is more of an active extinguishing system vs a suppression system like sprinklers. It sits closer to a hood extinguishing system or a fire extinguisher itself rather than a sprinkler system. Without a doubt I can see this end up in higher end, large homes, targeting specific ignition sources. Most homes are built without sprinklers anyway. Certainly the fact that all you need is power to it makes it appealing for easier placement and maintenance.
Another note for the author, you will NOT get any additional certification regarding the NFPA. What the NFPA is saying is that it is up to the local inspector / code whether this system is accepted as an alternative to a sprinkler. Which means it will fight an uphill battle for decades as more and more fire departments become familiar and accept the technology.
Note, I’ll get downvoted here but this is actually one of the problems we have in the US, the lack of a unified building code. Life safety and physics don’t change across a county line. (And yes, building codes are universal and can apply anywhere. You haven’t read a model code if you don’t understand that). It is a huge hidden cost driver.
