Fire Suppression System
ENVIRONMENTAL IMPACT
INERGEN agent is a mixture of three
naturally occurring gases: nitrogen, argon,
and carbon dioxide. As INERGEN agent is
derived from gases present in the earth’s
atmosphere, it exhibits no ozone depleting
potential, does not contribute to global
warming, nor does it contribute unique
chemical species with extended atmospheric
lifetimes. Because INERGEN agent is
composed of atmospheric gases, it does not
pose the problems of toxicity associated with
the chemically derived Halon alternative
agents.
PRODUCT DESCRIPTION
The INERGEN Fire Suppression System,
manufactured by Ansul, is an engineered
system utilizing a fixed nozzle agent distribu-
tion network. The system is designed and
installed in accordance with the National Fire
Protection Association (NFPA) Standard
2001, ‘‘Clean Agent Fire Extinguishing
Systems.’’ When properly designed, the
INERGEN system will extinguish surface
burning fire in Class A, B, and C hazards by
lowering the oxygen content below the level
that supports combustion.
INERGEN agent has also been tested by
FMRC for inerting capabilities. Those tests
have shown that INERGEN agent, at design
concentrations between 40% and 50%, has
successfully inerted mixtures of propane/air,
and methane/air.
The system can be actuated by detection
and control equipment for automatic system
operation along with providing local and
remote manual operation as needed.
Accessories are used to provide alarms,
ventilation control, door closures, or other
auxiliary shutdown or functions.
When INERGEN agent is discharged into a
room, it introduces the proper mixture of
gases that will allow a person to breathe in a
reduced oxygen atmosphere.
A system installation and maintenance
manual is available containing information on
system components and procedures
concerning design, operation, inspection,
maintenance, and recharge.
The system is installed and serviced by
authorized distributors that are trained by the
manufacturer.
Basic Use – The INERGEN system is partic-
ularly useful for suppressing fires in hazards
where an electrically non-conductive medium
is essential or desirable; where clean-up of
other agents present a problem; or where the

hazard is normally occupied and requires a
non-toxic agent.
The following are typical hazards protected
by INERGEN systems:
• Computer rooms
• Subfloors
• Tape storage
• Telecommunication/Switchgear
• Vaults
• Process equipment
• All normally occupied or unoccupied elec-
tronic areas where equipment is either very
sensitive or irreplaceable
Composition and Materials – The basic
system consists of extinguishing agent stored
in high strength alloy steel cylinders. Various
types of actuators, either manual or auto-
matic, are available for release of the agent
into the hazard area. The agent is distributed
and discharged into the hazard area through
a network of piping and nozzles. Each nozzle
is drilled with a fixed orifice designed to
deliver a uniform discharge to the protected
area. On large hazards, where three or more
cylinders are required, a screwed or welded
pipe manifold assembly is employed. The
cylinder(s) is connected to the distribution
piping or the manifold by means of a flexible
discharge bend and check valve assembly.
Additional equipment includes – Control
panels, releasing devices, remote manual
pull stations, corner pulleys, door closures,
pressure trips, bells and alarms, and pneu-
matic switches. All or some are required
when designing a total system.
INERGEN Agent – INERGEN agent is a
mixture of three inerting (oxygen diluting)
gases: 52% nitrogen, 40% argon, and 8%
carbon dioxide. INERGEN gas extinguishes
fire by lowering the oxygen content below the
level that supports combustion. When
INERGEN agent is discharged into a room, it
introduces the proper mixture of gases that
still allow a person to breathe in a reduced
oxygen atmosphere. It actually enhances the
body’s ability to assimilate oxygen. The
normal atmosphere in a room contains 21%
oxygen and less than 1% carbon dioxide. If
the oxygen content is reduced below 15%,
most ordinary combustibles will cease to
burn. INERGEN agent will reduce the oxygen
content to approximately 12.5% while
increasing the carbon dioxide content to
about 3%. The increase in the carbon dioxide
content increases a person’s respiration rate
and the body’s ability to absorb oxygen.
Simply stated, the human body is stimulated
by the carbon dioxide to breathe more deeply
and rapidly to compensate for the lower
oxygen content of the atmosphere.
Cylinders – The cylinders are constructed,
tested, and marked in accordance with
applicable Department of Transportation
(DOT) specifications. As a minimum, the
cylinders must meet the requirements of
DOT 3AA3000.
Cylinder Assembly – The cylinder assembly
is of steel construction with a red standard
finish. One size is available. Each cylinder is
equipped with a pressure seat-type valve
equipped with gauge. The valve is construct-
ed of forged brass and is attached to the
cylinder providing a leak tight seal. The valve
also includes a safety pressure relief device
which provides relief at 4000-4480 psi
(276-309 bar) per CGA test method. Cylinder
charging pressure is 2900 psi at 70 °F
(200 bar at 21 °C). The cylinders are shipped
with a maintenance record card and shipping
cap attached. The cap is attached to the
threaded collar on the neck of each cylinder
to protect the valve while in transit. The cylin-
der serial number and date of manufacture
are stamped near the neck of each cylinder.
Electric Actuator – Electric actuation of an
agent cylinder is accomplished by an
electric actuator interfaced through an
AUTOPULSE
®
Control System. This actuator
can be used in hazardous environments
where the ambient temperature range is
between 32 °F and 130 °F (0 °C and 54 °C).
In auxiliary or override applications, a manual
lever actuator can be installed on top of the
actuator.
Manual or Pneumatic Actuators – Three
types of manual actuators are available for
lever actuation on the cylinder valve. Manual
actuation is accomplished by pulling the
hand lever on the actuator.
Detection System – The AUTOPULSE
Control System is used where an automatic
electronic control system is required to
actuate the INERGEN system. This control
system is used to control a single fixed fire
suppression or alarm system based on
inputs received from fire detection devices.
The detection circuits can be configured
using cross, counting, independent or priori-
ty-zone (counting) concepts. The control
system has been tested to the applicable
FCC Rules and Regulations for Class A
Computing devices.
