FM200 Fire Suppression System is known as HFC227ea. FM-200 system is designed, installed and maintained according to NFPA 2001 (Clean Agent Fire Extinguishing Systems). SE-200 utilizes the halocarbon gas Heptafluoropropane (HFC-227ea) In NFPA 2001 and ISO:14520-1. The general requirements and design criteria are based on both NFPA 2001 and ISO 14520-1.
SR -200 is employed as a total flooding system and should not be used for local ap- plication system. SR-200 suppresses fire by absorbing heat energy at its molecular level faster than they can be generated, so they cannot sustain itself.
The extinguishing agent used in this Fire Suppression System is HFC-227ea. The speciality of this agent is that it is extremely rapid and effective. Once discharged, HFC-227ea systems reach extinguishing levels begins combating the fire in a matter of less than 10 seconds.
HFC-227ea is a gaseous halocarbon agent containing no particles; it leaves no oily residues on electronic equipment and can be removed and can be removed from the protected space by ventilation. It is the first environmentally acceptable replacement for Halon 1301.
The present understanding of the functioning of HFC-227ea is that 80% of its firefighting effectiveness is achieved through heat absorption and 20% through direct chemical means. HFC-227ea is stored as a liquefied compressed gas super pres-surized with dry nitrogen to 25BAR and is discharged into the protected area as a vapor.
