Section 1 General Information
1 GENERAL INFORMATION
e Janus Fire Systems® Sv, Mv, and Lv Series Fire Extinguishing Systems utilize FM-200® to protect
high value assets in areas that may be normally occupied, in locations where clean-up of other agents is
problematic, when storage space for a re suppression agent is restricted, and/or when an electrically non-
conductive agent is required.
FM-200® systems may be used in Class A (wood,paper,cloth,rubber,and many plastics),Class B (ammable
liquids and ammable gases), and Class C (energized electrical equipment) surface res.
NFPA 2001 mandates that clean agents such as FM-200® shall not be used on res involving the following
materials unless they have been tested to the satisfaction of the authority having jurisdiction:
• Chemicals or mixtures of chemicals, such as cellulose nitrate and gunpowder, that are capable of rapid
oxidation in the absence of air
• Reactive metals, such as lithium, sodium, potassium, magnesium, titanium, zirconium, uranium, and
plutonium
• Metal hydrides
• Chemicals capable of undergoing autothermal decomposition, such as organic peroxides and
hydrazine
All systems described in this manual are intended only for total ooding application. NFPA 2001 denes
total ooding as the act and manner of discharging an agent for the purpose of achieving a specied minimum
agent concentration throughout a hazard volume.e FM-200® must be discharged within 10 seconds and
reach a minimum concentration level of 6.7% but not exceeding 9% in normally occupied spaces.
Note: Janus Fire System® Fire Extinguishing Systems are designed, manufactured, installed and UL listed
and FM approved to deliver a designated quantity of FM-200® in a "not to exceed" 10 second discharge
time. e "Duration of Protection (Hold Time)" as referenced in NFPA 2001, 2012 edition is a function
of the hazard enclosure's (room) integrity and not a function (or capability) of the re suppression systems
referenced in this publication.

Section 1 General Information
1.1 Listings and Approvals
When designed and installed according to the information contained in this manual,the Janus Fire Systems®
Sv, Mv, and Lv Series FM-200® Fire Extinguishing Systems are Underwriters Laboratories Inc. (UL) listed
and Factory Mutual (FM) approved for engineered systems. System equipment has been veried through
testing to function at ambient temperatures ranging from 32°F (0°C) to 130°F (54°C). Flow calculations
have been veried at ambient temperatures of 70°F ±10° (21.1°C ±5.5°). Storage outside of the range of
70°F ±10° (21.1°C ±5.5°) may result in inaccurate ow calculations and may cause one or more nozzles to
not discharge the calculated quantity of FM-200®.
1.2 Extinguishing Agent
FM-200® (HFC-227ea) is a colorless, non-toxic gas
and a clean, eective, environmentally acceptable,
electrically non-conductive re suppression agent.
It is formed from the elements carbon, uorine and
hydrogen (CF3CHFCF3 - heptauoropropane). e
primary extinguishing mechanism of FM-200® is heat
absorption, with a secondary chemical contribution from
the thermal decomposition of FM-200® in the ame.
Most metals, such as aluminum, brass, steel, and
stainless steel, as well as plastics, rubber, and electronic
components, are not aected by exposure to FM-200®.
In the Janus Fire Systems® FM-200® Fire Suppression
Systems, FM-200® is stored as a liquid in steel cylinders
and superpressurized with nitrogen to 360 psig (24.8
bar) at 70°F (21.1°C) to improve its ow characteristics.
When discharged, FM-200® vaporizes at the discharge
nozzles and becomes thoroughly mixed with the air
throughout the protected area reaching a predetermined
design concentration.
1.3 Safety Considerations
e United States Environmental Protection Agency (EPA) Signicant New Alternatives Policy (SNAP)
Program lists FM-200® (HFC-227ea) as acceptable for occupied spaces.
FM-200® must be used in accordance with the NFPA Standard 2001, specically as follows:
Unnecessary exposure to FM-200® — including exposure at and below the no observable adverse
eects level (NOAEL)¹concentrations of 9% or below — and FM-200® decomposition products
shall be avoided. Means shall be provided to limit exposure to no longer than 5 minutes. Unprotected
personnel shall not enter a protected space during or after agent discharge. e following additional
provisions shall apply:
1NOAEL (No Observed Adverse Effect Level) - The highest concentration at which no adverse toxicological or physiological effect has been
observed.

Section 1 General Information
(1) FM-200® systems for spaces that are normally occupied and designed to concentrations up to the
NOAEL shall be permitted. e maximum exposure in any case shall not exceed 5 minutes.
(2) FM-200® systems for spaces that are normally occupied and designed to concentrations above
the NOAEL shall be permitted, given that means be provided to limit exposure to the design
concentrations shown in Table 1.3 that correspond to an allowable human exposure time of 5
minutes. Higher design concentrations associated with human exposure times less than 5 minutes
as shown in Table 1.3 shall not be permitted in normally occupied spaces. An exposure and egress
analysis shall be performed and approved.
(3) In spaces that are not normally occupied and protected by an FM-200® system designed to
concentrations above the lowest observable adverse eects level (LOAEL)²of 10.5%, and where
personnel could possibly be exposed, means shall be provided to limit exposure times using Table 1.3.
(4) In spaces that are not normally occupied and in the absence of the information needed to
fulll the conditions listed above, the following provisions shall apply:
(a) Where egress takes longer than 30 seconds but less than 1 minute, the FM-200® shall
not be used in a concentration exceeding its LOAEL of 10.5%.
(b) Concentrations exceeding the LOAEL are permitted provided that any personnel in
the area can escape within 30 seconds.
(c) A pre-discharge alarm and time delay shall be provided in accordance with the provisions
noted in NFPA 2001 for Time Delays.
e discharge of FM-200® into a hazard may reduce visibility for a brief period. FM-200® may cause
frostbite if liquid discharge or escaping vapor contacts the skin.
e Material Safety Data Sheet (MSDS) on FM-200® can be found in Appendix A of this manual
and should be read and understood before working with the agent. Training of personnel, re drills, and
evacuation plans should be considered.
Acylinder containing FM-200® must be handled carefully. All anti-recoil safety plugs and devices must be in
place at all times when the cylinder is not connected to discharge piping.
2LOAEL(Lowest Observable Adverse Effect Level) - The lowest concentration at which an adverse physiological or toxicological effect has been
observed.
When FM-200® is exposed to temperatures greater than 1300°F (700°C), the potentially hazardous byproduct
hydrogen uoride (HF) will be formed. The system is designed to discharge within 10 seconds or less to minimize
the amount of HF formed during extinguishment. The effects of agent decomposition on equipment must be
considered when using FM-200® in hazards with high ambient temperatures (e.g., furnaces and ovens).

Section 2 System Description and Components
2.1 Cylinder Assembly
e cylinder assembly consists of the cylinder, dip tube, and cylinder valve.
2.1.1 Cylinder
e FM-200® agent is stored as a liquid inside a welded steel cylinder. e cylinders are superpressurized
with dry nitrogen to a pressure of 360 psig (24.8 bar) at 70°F (21°C). Every cylinder has a minimum ll
density of 35 lb/ft3(561 kg/m3) and a maximum ll density of 70 lb/ft3(1121 kg/m3). e capacity of a
cylinder varies according to the design requirements and the Series designation (See Table 2.1.1 for a list
of available capacities).
Standard domestic cylinders are manufactured according to the requirements of the U.S. Department
of Transportation (USDOT) and Transport Canada1(TC) for compressed gas and are tted with an
identication label indicating the ll quantity of FM-200®. Each cylinder has internal neck threads to allow
for connection to the cylinder valve.
2.1.1.1 Rupture Disc
A frangible rupture disc is tted to the Lv Series cylinder body. It functions as an emergency relief device in
the event of excessive internal pressure within the cylinder. Its rupture point is between 850 psi (58.6 bar)
and 1000 psi (68.9 bar).
is feature is not found on the Sv Series or Mv Series cylinder. Instead, a rupture disc is located on the side
of Sv Series and Mv Series cylinder valve as detailed in sections 2.1.3.1 and 2.1.3.2.
