FM 200

FM200 Gas Fire Extinguishing Systems

FM 200 FM-200® extinguishing agent is a clean gas widely accepted as substitute to Halon. FM-200® or heptafluoropropane (CF3CHFCF3), is suitable for the protection of most hazards where Halon 1301 had to be applied in the past. Because FM-200® is not electrical conductive, (but it is odourless and colourless). it is effective in the protection of electrical hazards, such as computer rooms.

Furthermore, it is suitable for class A fires (fires including solid materials] as well as for class 8 fires (flammable liquids].

- Suitable for occupied areas
- Discharge time:10 seconds
- No residue to clean up after discharge
- Widely accepted as substitute to Halon 1301
- Compliance with standards IS0-14520 and NFPA 2001
- Suitable for storage in welded high pressure cylinders, saving space and money
- Electrically non - conductive
- Zero Ozone Depletion Potential

Where To Use It:

FM 200 - With electrical or electronic equipment
- Archives
- Stores
- Cable ducts
- Engine rooms
- Flammable liquids
- Hazards with people inside FM-200® extinguishes fires mainly by physical means, weakening and extinguishing the fire by absorbing heat.
- Once discharged, FM-200® extinguishes the fire quickly reducing to a minimum damages to property and valuable equipment, likewise ensuring total safety to persons.
- LPG systems containing FM-200® are designed to discharge within 10 seconds. Extinguishing agent pressurized with dry Nitrogen at 42 bar and stored in steel cylinders fitted with approved valves.
