Section 1 General Information
1 GENERAL INFORMATION
is manual describes the procedure for lling Janus Fire Systems® Sv Series, Mv Series, and Lv Series
cylinder assemblies with FM-200® agent.
1.1 Listings and Approvals
To maintain FM Approval for Janus Fire Systems® Fire Suppression Systems, cylinder recharge must be
performed at a Janus Fire Systems® recognized facility.
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 Janus Fire Systems® FM-200® Fire Suppression Systems, the FM-200® agent 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
All safety guidelines contained in this manual must be read and understood before lling any Janus Fire
Systems® cylinder. All applicable guidelines shall be followed before, during, and after the ll procedure
including any additional local standards or regulations determined by the authority having jurisdiction
(AHJ). Where the guidelines in this manual and local guidelines or regulations conict, the most stringent
requirement should be followed.
ose individuals responsible for the lling of a Janus Fire Systems® FM-200® cylinder assembly must be
trained.
At a minimum, Janus Fire Systems recommends the following safety equipment be worn at all times during
the ll procedure:
• Work boots with protective toe guards
• Safety glasses or goggles
• Gloves to prevent injury of the hands or ngers.
• Properly tting clothing.
• Properly tting ear plugs or other hearing protection.

Section 1 General Information
Cylinder lling must be performed in a well ventilated area.
When FM-200® is exposed to temperatures greater than 1300°F (700°C), the potentially hazardous byproduct
hydrogenuoride(HF)willbeformedduringagentdecomposition.Heatsourcessuchasspaceheaters,torches,
welding equipment, or lit cigarettes are capable of reaching temperatures that initiate agent decomposition. All
suchpotentialheatsourcesmustbeclearedfromtheworkareabeforebeginningllprocess.Smokinginthe
vicinityofthellingequipmentoragentstoragecontainersshallbeprohibited.
e Material Safety Data Sheet (MSDS) on FM-200® can be found in Appendix A of this manual and shall
be read and understood before working with the agent. Refer also to DuPont FM-200® Fire Extinguishing
Agent Properties, Uses, Storage and Handling document K23261 found at www2.dupont.com/FE/en_US/
tech_info/index.html for specic agent handling procedure.
Accidental discharge of an unsecured cylinder may result in property damage, injury, or death from
violent cylinder movement.Cylinderassembliesmustberestrainedatalltimesduringthellprocedure.Anti-
recoilsafetyplugsanddevicesmustbeinplaceatalltimesthecylinderassemblyisnotconnectedtoagentll
lines or discharge piping. Do not transport the cylinder unless the anti-recoil safety device is in place. Handle the

Section 2 Cylinder Assembly
2 CYLINDER ASSEMBLY
e cylinder assembly consists of the cylinder, dip tube, and cylinder valve.
2.1 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 for a list of
available capacities).
Standard domestic cylinders
are manufactured according
to the requirements of
the U.S. Department of
Transportation (USDOT)
andTransport 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 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 2.3.1 and 2.3.2.
2.1.2 Liquid Level Indicator
e liquid level indicator consists of a sealed non-magnetic tube containing an external measurement tape
tted with a magnet. A second magnet with an opposing polarity is installed on the outside of the tube and
is exposed to the FM-200® liquid. As the tape is extracted from the tube, it will engage with the second
magnet creating a noticeable change in tension. e measure on the tape when this change in tension
occurs indicates the current liquid level inside the cylinder and can then be compared to a chart located in
Appendix B of this manual to determine the current ll weight of the cylinder.
e liquid level indicator assembly is threaded into an outlet on the head (top) of the Mv Series and Lv
Series cylinders.
is feature is not found on the Sv Series cylinder.

tting unless it is connected to the ll station.
3.2.2 Cylinder Connection Port
e cylinder connection port is located opposite of the pump connection port and is a 1/4 in (8 mm) female
quick-connect tting that serves as the connection point for the 1/4 in (8 mm) male quick-connect tting
on the ll adapter (refer to section 3.1). e female quick-connect tting of the cylinder connection port
contains an internal check valve that prevents agent from owing through the tting unless it is connected
to the ll adapter.
3.2.3 Gauge Connection Port
e gauge connection port is a 1/4 in (8 mm) male quick-connect tting that serves as the connection point
for the ll pressure gauge. It is located on the same side of the cylinder ll assembly as the handle for the
manual agent ll valve. When connected to the cylinder valve, the cylinder ll assembly must be oriented
so that the gauge connection port is perpendicular to the ground and pointing upwards. e male quick-
connect tting of the gauge connection port contains an internal check valve that prevents agent from
owing through the tting unless the ll pressure gauge has been installed to it.

3.2.4 Nitrogen Pressurization Port
e nitrogen pressurization port is located opposite of the gauge connection port and is a 1/4 in (8 mm) male
quick-connect tting that serves as the connection point for the nitrogen supply used to superpressurize
the cylinder assembly. When connected to the cylinder valve, the cylinder ll assembly must be oriented
so that the nitrogen pressurization port is perpendicular to the ground and pointing downwards. e male
quick-connect tting of the gauge connection port contains an internal check valve that prevents agent
from owing through the tting unless it is connected to the nitrogen supply.
3.3 Nitrogen Regulator/Hose Assembly
P/N 99516 (See Figure 3.3)
e nitrogen regulator/hose assembly is comprised
of a self-relieving pressure regulator, a safety
relief valve, and two manually actuated ball valves
connected to hose lines ending in female quick-
connect ttings. e regulator-hose assembly serves
as a connection point between the nitrogen supply
and both the nitrogen pressurization port of the
cylinder ll assembly and the inlet port of the valve
closing adapter. e regulator has a CGA tting for
attaching to the nitrogen supply.
3.3.1 Valve Closing Line
e valve closing line refers to the ex hose and manually actuated ball valve in line with the pressure
regulator. e valve closing line ends with a 1/4 in (8 mm) female quick-connect tting that attaches to
the 1/4 in (8 mm) male quick-connect tting located on the inlet of the valve closing adapter (see Section
3.4). It is used to close the cylinder valve by applying pressure to the top of the cylinder valve piston. e
valve closing line quick-connect tting contains an internal check valve that prevents nitrogen from owing
through the tting unless it is connected to the valve closing adapter.
3.3.2 Cylinder Pressurization Line
e cylinder pressurization line refers to the ex hose and manually actuated ball valve branching o from
the valve closing line and is perpendicular to the outlet of the pressure regulator. e cylinder pressurization
line ends with a 1/4 in (8 mm) female quick-connect tting that attaches to the nitrogen pressurization
port of the cylinder ll assembly. It is used to supply the nitrogen required to superpressurize the cylinder
assembly following agent ll. e cylinder pressurization line quick-connect tting contains an internal
check valve that prevents the nitrogen from owing through the tting unless it is connect to the nitrogen
pressurization port.
