Roomsafer Gaseous Fire Fighting Systems

Roomsafer offers a wide range of gaseous systems for different applications  including FM200 and CO2 systems.

Roomsafer FM200 systems are based on many years experience in the design, supply, installation and commissioning of gaseous fire fighting systems.

During this time Halons have provided industry and commerce with a unique and versatile extinguishant to respond to most fire protection needs.

FM200(HFC 227ea) is known chemically as Heptafluoropropane.FM200 is a colourless gas which is liquified under pressure for storage. Like Halon 1301 it has a low toxicity level and is superpressurised with Nitrogen to 24.8bar(360psi). It rapidly extinguishes most commonly found fires through a combination of chemical and physical mechanisms.


  • Zero ozone depleting potential

  • Safe for use in occupied areas

  • Suitable for protection on a range of high value risks

  • Existing Halon/CO2 control systems can be adapted for use with FM200

  • Requires minimal storage space

  • Like Halon, no clean-up required after discharge

  • Low pressure system

  • Listed in BPFSA Code of Practice, NFPA 2001 and draft ISO

  • Listed in the US Environmental Protection

  • Agency(EPA) Significant New Alternatives(SNAP) programme for the total flooding of occupied spaces UL and FM approved as a component in approved systems



FM200 contains no bromine or chlorine and therefore has zero Ozone Depleting Potential(ODP). The atmospheric lifetime of FM200 is between 31 and 42 years which along with its zero ODP presents a long-term solution to fire protection requirements.



FM200 has been found to be less toxic than Halon 1301, which makes it safe for use in the fully automatic mode in occupied areas.

Typically FM200 requires a design concentration of 7%, which is well below the 9% No Observable Adverse Effect Level(NOAEL) on cardiac sensitisation. The NOAEL for Halon 1301 is only 5%(the same as its design concentration).
