I have a little experience with this. I have seen a system brand called "Flamex" on the dust collection ducts. This system uses flame sensors and solenoids to extinguish a fire in the duct, which is a better system than just installing sprinklers in there. I can say that installing sprinklers in the top of the filter units is a good idea. I have seen fires in these at a couple of facilities, and the employees on one of the sites later admitted "it was a whole lot cheaper to buy the filters that aren't flame resistant, like the manufacturer recommends..." The Flamex people can be helpful if you give them a call (it is what they do). Be very careful about your liability with these systems (speaking of which, this email is by no means a substitute for an engineered fire protection system), and it is important to mention these usually have a high explosion (read: deflagration) risk, which needs to be addressed. Also, you might consider some kind of physical protection for any heads you install. I hope this was helpful, because I know how I felt when I first started going through these systems.
