Hello all, I am protecting a door manufacturing facility. There is a spark detection and extinguishing system with 48" ducts conveying wood dust released by equipment having a high frequency of generated sparks. I have looked at NFPA 664 and 13 but there is no direction on how the system is monitored. The best place to connect the piping is the fire line since it has a backflow preventer installed. Can I connect this system to the fire protection manifold below the valves? Do I need to monitor the flow of water to the nozzles using a 1 1/2" flow switch? The normal operation of the guillotine nozzles will be a flow for short bursts. This facility has a fire pump and jockey pump that maintains the system at 120 psi. Thank you in advance.
