Chemical Systems (Inergen & FM-200)

Chemical systems use pressurized chemicals to extinguish a fire.  The chemicals are called Inergen or FM-200.  These systems in some cases work in conjunction with a pre-action system.  They are controlled electrically with heat detectors and or smoke detectors.  They function when a series of alarms are activated which trips a solenoid on the header of the pressurized tanks allowing the chemical to discharge from the tanks and into the piping system.  The piping system ends to open nozzles which then blanket the chemical in the room being protected.  The chemical slowly falls to the ground extinguishing the fire.
