GENERAL INFORMATION
Fenwal Argonite Fire Protection Systems are clean
agent, automatic extinguishing systems that use Argonite
(IG55) and consist of four basic components and their
associated accessories:
®
• Argonite Cylinders and Components
• Completer Kits
• Control Panels
• Detection and Alarm Devices
Argonite is an inert gas mixture, in equal parts, of Nitrogen and Argon. Both substances are naturally occurring
and present in the atmosphere. Argonite is safe for use in
occupied spaces and poses no threat to the environment.
1.
2.
3.
4.
Argonite Components consist of the agent cylinders,
cylinder racking and the agent discharge nozzles.
The Completer Kits provide all the basic components necessary to operate the Argonite cylinders.
The kits consist of hoses, connection fittings, pressure gauges, actuation devices required to operate
the cylinder valve and warning signs to be displayed
in the area(s) protected by an Argonite fire extinguishing system.
The Control Panels vary in features and complexity
but in all cases are used to monitor the detection,
actuate the alarms, initiate the agent discharge and
control auxiliary functions such as shut down of vital
equipment and ventilation dampers.
The Detection and Alarm devices provide fire detection by means of thermal or smoke detectors, audible and visual pre-alarm warnings and annunciation
of the Argonite discharge.
AGENT DESCRIPTION
Argonite is a mixture of 50% pure Nitrogen and 50% pure
Argon. Argonite contains only naturally occurring substances, and as such, has no ozone depletion potential
and no direct global warming potential.
Argonite extinguishes by means of reducing the oxygen
content within a room to the point at which fire can no
longer burn, but without compromising the safety of individuals present. There are no toxicological factors associated with the use of Argonite. Argonite will not
decompose or produce any by-products when exposed
to a flame from a fire condition.
Most Argonite systems are designed to extinguish fires
with a minimum agent concentration of 37.9% achieved
within one minute. This results in extinguishment of the
fire and an oxygen concentration of 13%.
Argonite is stored as a gas within the cylinder assembly.
It is available at a storage pressure of 2900 PSI (200
bar).
Usable Cylinder Capacity
Cylinder and Valve Assembly
Three cylinder sizes are available (see Table 1).
Argonite cylinders are available in three different sizes.
The 2900 PSI (200 bar) cylinders are uniquely color
coded to allow for quick and easy identification. The cylinders are red with yellow-green at the cylinder shoulder.

Because Argonite is stored as a gas, the cylinders have
no dip tube and can be mounted in either the vertical or
horizontal position.
The cylinder valve, required for all system cylinders,
allows for connection of the cylinders into the system.
The valve provides connections for electric, pneumatic
and manual release of the cylinder contents, as well as a
discharge outlet, connected by a discharge hose, to the
distribution piping.
The actuator operates on a 1 to 10 ratio requiring only
300 PSI (21 bar) for the 2900 PSI (200 bar) system to
operate the valve. The following are the connections provided on the valve.

Bleeder Valve for Actuator, P/N 38-509840-001
A bleeder valve is included with the Pilot Completer Kit to
prevent an accidental accumulation of pressure within
the pilot lines, which, if not bled to atmosphere, could
cause a false discharge. Connection requires a copper
gasket between the bleeder valve and pneumatic actuator.
Check Valve Assembly, P/N 38-509833-001
To prevent accidental discharge of the Argonite into unintended areas, a check valve is required for each discharge hose in all multi-cylinder systems. All Fenwal Fire
Systems manifolds are constructed of threaded pipe
with welded check valve connections and include preinstalled check valves. All customer connections are via
threaded pipe.
Note:
For single cylinder systems, a 1/2-in. BSP x
1/2-in. FNPT adapter is required to connect the
discharge hose (BSP) to the Schedule 160 pipe
(NPT).

The restrictor assembly reduces the initial Argonite pressure from the discharge manifold to between 174 and
870 PSI (12 and 60 bar) before entering the discharge
piping. The size of the orifice within the restrictor is determined through calculations based upon the required flow
and discharge time.

SELECTOR VALVES
Nozzles
Argonite systems are particularly suited to the use of
selector valves, where one central storage of agent is
used to provide protection to two or more hazard areas.
The brass discharge nozzles are available in four basic
sizes 1/2 inch, 3/4 inch, 1 inch and 1½ inch. Each is fitted
with a drilled orifice to assure proper flow rates, agent
quality and proper discharge timing as determined by
flow calculations. Maximum nozzle spacing for room
mounted nozzles should not exceed 18.8 feet (5.7 m)
square. Nozzle height should not exceed 16 feet (4.9 m)
from a single layer of nozzles.
Selector valves are available in six sizes, and are pneumatically operated. One common pressure regulator and
vented elbow are also required to reduce the actuation
pressure to each set of selector valves.
