Introduction
FM-200® is a clean, safe fire fighting agent for use in
total flooding automatic extinguishing systems. It is intended
as a long term replacement for Halon 1301 and,
whilst maintaining the excellent fire suppression properties
of Halon, has none of the environmental problems.
Storage and distribution requirements are similar
to Halon and the majority of system components are
identical. However, FM-200® is not a direct replacement
for existing Halon 1301 installations due to the difference
in agent quantity and discharge characteristics.
The minimum FM-200® design concentration for Class
A hazard is 6.4% for UL Listed systems or 7.17% for FM
Approved systems, and for Class B hazard is at least
9.0%, therefore requires approximately 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
US 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 NFPA 2001, 2000 edition "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® containers, manifolded together and
connected via a pipe network to a number of discharge
nozzles.
Systems may be activated mechanically or electrically.
Mechanical manual actuation is via a strike knob
attached to the container valve. Electrical actuation is
via a removable side mounted solenoid. The solenoid
can be energised automatically 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, operate 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
specialist engineers for the matter to be quickly resolved.

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, 2000 edition and
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 BS Standards
may additionally be utilized to specific system requirements
for these purposes.
Health and Safety
A properly designed and installed extinguishing system
should not present any significant health or safety problems,
however, there are basic precautions to be taken to
avoid accidents, 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. Current best practice should be observed
e.g. BS5306: Part 5: Section 5.1 and the BFPSA
Code of Practice for Gaseous Fire Fighting Systems.
Reference should also be made to NFPA 2001 and BFPSA
Volume 3 section 19 A review of the toxic and asphyxiating
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 CO2 and 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, 2000 edition
Section 1-6 "Safety," for exposure requirements. As
with halons, the US 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 decomposition 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 odour long before hazardous maximum
exposure levels are reached. Fire toxicity studies conclude
that generally decomposition products from the
fire itself, especially carbon monoxide, smoke, heat, and
oxygen depletion, create a greater hazard.
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 protected area to
move paper and light objects.
Direct contact with the vaporising 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 vaporises rapidly when mixed with air and
therefore limits the risk to the immediate vicinity of the
nozzle. Minor reduction in visibility may occur for a brief
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 results from exposure
of the agent to the fire or hot surfaces. Unnecessary
exposure of personnel either to the natural agent or
to the products of decomposition shall be avoided.

FM-200® Installation Guide/11150/05.08.05/Issue 1.1 7
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:
o The low concentration of FM-200® required means
less visual obscurity and minimal risk to personnel.
o The small quantity of agent discharged minimises
over-pressurisation of the protected area.
o Maximum safety for personnel due to low toxicity.
o Most effective when used with automatic detection
to introduce FM-200® rapidly.
o The ability to prevent re-ignition as long as concentration
levels are maintained.
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(HSE)4BW500 or DOT(HSE)4BW450
containers and is super-pressurised with dry nitrogen
to 25 Bar @ 210 C (360 PSI @ 70 0F).
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 guidelines 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 (Reference GLCC). The US EPA SNAP does not
consider FM-200® to be a long lived substance when
discharged, and as such has placed no restrictions on
its use. (Environmental Protection Agency's Significant
New Alternatives Program).

The bracket assembly consists of a nut and bolt, two
bracket straps and one back channel. To securely hold
the container in position during the system discharge,
two bracket assemblies are required per container. The
only exception is the 8 litre container which only requires
one.
Each strap is notched for insertion into the back channel
allowing the container to be properly aligned. The bracket
assembly is designed to be mounted to a rigid vertical
surface with the container assembly resting fully on the

Principle of Operation
The Macron Safety Systems FM-200® valve is a highflow-
rate device specially designed for fire protection
use. Operation is by means of a pressure-differential piston.
Container 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
shuttle 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.

Pneumatic Actuator
The pneumatic actuator is an assembly similar to the
manual actuator but without the strike knob. Pressure
from a ‘master’ container or other sources is used to
actuate the valve, via small bore piping or, preferably, a
flexible hose.

Side Mounted Electrical Actuator
This solenoid actuator differs from other actuators in
that it is side mounted. It can be located directly on the
side of the valve or via a solenoid adaptor. The adaptor
enables the actuator to be removed safely without actuation
of the container valve. It is designed to be used
in explosive atmospheres (Class I , groups C and D, Class
II, groups E, F & G). It is operated by a 24v dc input
signal.

25mm & 50mm Flexible Discharge Hose
Multiple FM-200® container installations are connected
to the system by means of a flexible discharge hose.
This enables containers to be disconnected for maintenance
or recharge without dismantling other container
mountings, manifold connections and pipework, etc.
The flexible discharge hose is connected to each manifold
valve outlet. A swivel fitting at the inlet of the hose
enables the container to be readily coupled to the distribution
system. The 32mm (1 1/4") discharge hose (Part
No.4120) requires the addition of a brass adapter (Part
No. 6412) between the valve outlet and the swivel fitting
at the inlet of the hose.
