Introduction
FM-200®is a clean, safe fire fighting agent for use in total
flooding automatic suppression systems. It is intended as a
long term replacement for Halon 1301 and, while maintaining
the excellent fire suppression properties of Halon, has none of
the environmental problems. Storage and distribution require-
ments are similar to Halon and the majority of system compo-
nents are identical. However, FM-200®is not a direct replace-
ment for existing Halon 1301 installations due to the difference
in agent quantity and discharge characteristics. The FM-200®
design concentration for Class A hazards is 7.17% and for
Class B hazards is at least 9.0%, therefore requiring approxi-
mately 45% additional storage capacity over that required for
Halon in the same area.
The manufacturers claim that FM-200®is safer than Halon
1301 for use in total flooding applications and the U.S.
Environmental Protection Agency (EPA) accepts extended use
exposures of up to 9%. This has been further confirmed by a
recently published HAG report. FM-200®is rated as Zero
Ozone Depletion (ODP), is electrically non-conductive, clean,
and leaves no residue. Refer to NFPA2001, “Clean Agent Fire
Extinguishing Systems,” Section 1-6 “Safety,” for additional
exposure requirements.
The systems described in this manual are 'engineered.’
Engineered systems for example can consist of several FM-
200®tanks, manifolded together and connected via a pipe net-
work to a number of discharge nozzles.
Systems may be activated mechanically or electrically.
Mechanical manual actuation is via a strike knob attached to
the tank valve. Electrical actuation is via a removable side
mounted solenoid. The solenoid can be energized automatical-
ly by a signal from a detection and alarm control panel.
Users of this manual should find that sufficient information
is provided to plan, design, purchase components, install, oper-
ate and maintain the system. However, in the event that part of
the document is not understood, or if there is any concern as to
the suitability of the protection, do not hesitate to contact one
of our application engineers for the matter to be quickly
resolved.

Pyro-Chem FM-200®Suppression System Units are to be
designed, installed, inspected, maintained, tested and
recharged by qualified, trained personnel in accordance with
The Standard on Clean Agent Fire Extinguishing Systems,
NFPA2001. To be used in accordance with Environmental
Protection Agency (EPA) Significant New Alternatives
Program (SNAP). Where determined to be appropriate by the
authority having jurisdiction, applicable NFPA Standards may
additionally be utilized to specific system requirements for
these purposes.
Health and Safety
A properly designed and installed suppression system
should not present any significant health or safety problems;
however, there are basic precautions to be taken to avoid acci-
dents, and aspects of the system operation that should be
understood. End-users often require reassurance regarding the
safety of personnel, and this can only be given if a thorough
understanding of the properties of the agent and its effects in
different situations are known.
Reference should be made to NFPA2001 for the toxic and as-
phyxiating hazards of clean agents replacements for Halon 1301.
FM-200®, like halon, extinguishes by causing a chemical
reaction with the combustion products, and does not remove
oxygen like CO2and other inert agents.
Therefore, exposure to FM-200®at the design concentration
of 7.17%, and up to 9.0%, is not hazardous to health. Exposure
to higher concentrations is permissible for limited periods.
Refer to NFPA 2001, Section 1-6 “Safety,” for exposure
requirements. As with halons, the EPA and the National Fire
Protection Association (NFPA) recommend that unnecessary
exposure to any agent be avoided and that personnel evacuate
protected areas as quickly as possible to avoid the decomposi-
tion products of the fire.
FM-200®can decompose at high temperatures to form
halogen acids. If so, their presence is readily detected as a
sharp, pungent odor long before hazardous maximum exposure
levels are reached.
The noise created by the FM-200®agent discharging can be
loud enough to startle people in the vicinity, but is unlikely to
cause any permanent injury. Turbulence caused by the high
velocity discharge can dislodge substantial objects directly in
its path, and cause enough general turbulence within the pro-
tected area to move paper and light objects.
Direct contact with the vaporizing liquid discharged from an
FM-200®nozzle has a chilling effect on objects and in extreme
cases can cause frostbite to the skin. The liquid phase vaporizes
rapidly when mixed with air and therefore limits the risk to the
immediate vicinity of the nozzle. Reduction in visibility will
occur due to the condensation of water vapor.

First Aid
Skin Maintain at body temperature, thaw affected area with
gentle heat. If frostbite occurs, seek medical attention.
Do not rub affected area.
Eyes Apply gentle heat. Do not allow patient to touch affect-
ed area.
WARNING
The discharge of clean agent systems to extinguish a
fire can result in a potential hazard to personnel from
the natural form of the clean agent or from the products
of combustion that result from exposure of the agent to
the fire or hot surfaces. Unnecessary exposure of per-
sonnel either to the natural agent or to the products of
decomposition shall be avoided.

SECTION 1 – INTRODUCTION

FM-200®Agent Characteristics
FM-200®(HFC-227ea) is a clean, gaseous agent containing no
particles or oily residues. It is produced under ISO 9002 guide-
lines to strict manufacturing specifications ensuring product
purity. FM-200®leaves no residue or oily deposits on delicate
electronic equipment, and can be removed from the protected
space by ventilation.
FM-200®is thermally and chemically stable, but without
the extremely long atmospheric lifetimes associated with other
proposed halon replacements. 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 dis-
charged, and as such has placed no restrictions on its use.
Typical areas that can be protected by an FM-200®system
are detailed below; the list is by no means complete:
Bank Vaults
Libraries
Rare Book Stores
Electronic Data Processing
Telephone Exchanges
Studios
Communication Centers
Transformer and Switchrooms
Control Rooms
Test Laboratories
Flammable Liquid Stores
The present understanding of the functioning of FM-200®is
that 80% of its fire fighting effectiveness is achieved through
heat absorption and 20% through direct chemical means
(action of the fluorine radical on the chain reaction of a flame).
Complete suppression using FM-200®has the following
advantages:
•The low concentration of FM-200®required means less
visual obscurity and minimal risk to personnel.
•The small quantity of agent discharged minimizes over-
pressurization of the protected area.
• Maximum safety for personnel due to low toxicity.
•Most effective when used with automatic detection to intro-
duce FM-200®rapidly.
•The ability to prevent re-ignition as long as concentration
levels are maintained.
FM-200®is stored as a liquified compressed gas and is dis-
charged into the protected area as a vapor. It is stored in
approved DOT4BW450 or DOT4BW500 tanks and is super-
pressurized with dry nitrogen to 360 psi (25 Bar) at 70 °F
(21 °C).

Mounting Brackets
The bracket assembly consists of a nut, bolt, and two bracket
straps (back channel must be supplied by others. Approved
type of Unistrut Channel is series P1000T, 41 mm x 41 mm or
equal). To securely hold the tank in position during the system
discharge, two bracket assemblies are required per tank.
Exception: 8 liter size tank requires only one.
Each strap is notched for insertion into the back channel allow-
ing the tank to be properly aligned. The bracket assembly is
designed to be mounted to a rigid vertical surface with the tank
assembly resting fully on the floor.

Principle of Operation
The Pyro-Chem FM-200®valve is a high-flow-rate device spe-
cially designed for fire protection use. Operation is by means
of a pressure-differential piston. Tank pressure is used within
the valve to create a positive force on the piston, sealing the
valve closed. Operation of the valve occurs when the upper
chamber is vented faster than the 'make up device' in the shut-
tle can replace the pressure. Thereby allowing the shuttle to be
forced up, and free flow of FM-200®from the valve. Upper
chamber pressure is released by the electrical, mechanical or
pneumatic actuator.
