FM 200
FM-200 Suppression Systems
Historically,
the most widely used Halon 1301 replacement, FM-200™ provides waterless fire
suppression without leaving behind residue or particulate, and has been
installed in over one hundred thousand applications in more than 70 nations.

in 10 seconds or less to extinguish fires rapidly, minimizing damage to
high-value assets.
- App ears
on US Environmental Protection Agency (EPA) Significant New Alternatives
Policy (SNAP) list
- Designed
in accordance with NFPA 2001.
- UL listed
and FM approved.
- Marine
system with USCG and ABS approvals also available.
WHAT IS
FM-200™?
FM-200™
(HFC-227ea) is formed from the elements carbon, fluorine and hydrogen
(CF3CHFCF3-heptafluoropropane). The primary extinguishing mechanism of FM-200™
is heat absorption, with a secondary chemical contribution from the thermal
decomposition of FM-200™ in the flame.
FM-200™ fire
suppressant (HFC-227ea) can be safely used where people are present.
When used at standard design concentrations, it is safe for occupied spaces. FM-200™ leaves no residue. Most common metals, such as aluminum, brass, steel, cast iron, lead, stainless steel, and copper, as well as rubber, plastic, and electronic components, are unaffected when exposed to FM-200™ (HFC-227ea)
