What is FM-200 fire fighting system?
FM-200™, also commonly known as HFC-227ea, is a clean agent fire suppressant for Class A, B, and C fires and meets NFPA Standard 2001 Clean Agent Fire Extinguishing Systems. Clean agents are fast and effective in suppressing fires, are safe in occupied spaces, and do not leave a residue.
Which gas is used in FM-200 system?
Some of the most common gases used in fire suppression systems are: Carbon dioxide (CO2) Clean agents, including HFC-227ea (FM200) and FK-5-1-12 (Novec 1230)
What is design concentration in fire suppression system?
The minimum design concentration is set as 120% of the extinguishing concentration (20% safety factor) or 110% of the inerting concentration (10% safety factor). The actual safety factor may be different. The concentration may also tend towards higher values then the design concentration.
What is the pressure of FM-200 cylinder?
360 psi
FM-200 is stored as a liquified compressed gas and is discharged into the protected area as a vapour. It is stored in approved DOT 4BW500 containers and is super-pressurised with dry nitrogen to 25 bar @ 21 °C (360 psi @ 70 °F).
What is minimum design concentration?
1 The minimum design concentration for spaces containing energized electrical hazards supplied at greater than 480 volts which remains powered during and after agent discharge, shall be determined by testing, as necessary, and a hazard analysis.
Does FM-200 expire?
The atmospheric lifetime of FM-200 has been determined to be 36.5 years. The EPA does not consider FM-200 to be a long-lived substance when discharged, and as such, has placed no restrictions on its use.
What GPM is needed for sprinkler system?
What is the average flow rate? The standard sprinkler flow rates, in general, are from 4 gallons per minute (gpm) from a 5/32-inch nozzle at 30 pounds pressures to over 11 gpm from a 7/32-inch nozzle at 70 pounds pressures.
How does Kidde FM-200 work?
A Kidde FM-200 System suppresses fire by “flooding” the protected area with a 7% concentration of FM-200. Instead of inerting the entire area, FM-200 actively attacks the fire itself, soaking up heat like a sponge soaks up liquid and breaking down the fire’s molecular structure.
What kind of fire suppression system does Kidde use?
Clean Agent Fire Suppression Systems Kidde Fire Systems offers versatile FM-200™ (HFC-227ea) and 3M™ Novec™ 1230 clean agent fire suppression systems that equally provide a total flood fire protection solution to protect valuable assets in occupied areas.
How does the FM-200 work?
The FM-200’s chemical composition works to suppress fires by interrupting the chemical reaction and removing the heat which then stops the fire and prevents it from spreading. Unlike other fire suppression methods, the FM-200 clean agent system does not displace oxygen which allows the environment to remain safe for humans.
Is FM 200 approved by the NFPA?
It’s designed in line with NFPA 2001 and is UL/ULC listed, FM approved, EPA approved, and also offers a marine system with USCG and ABS approvals. FM-200 is suitable for a variety of fire hazard areas including spaces with class A, B, and C fire hazards.
