INTRODUCTION
UL / ULC Ex4623 Fike Clean Agent System w/ FM-200™ Page 1 of 1
FM 3010715 Manual P/N: 06-215 (Rev G) Revision Date: January, 2010
Fike is pleased to provide a “Design, Installation and Maintenance Manual” for our Clean Agent Fire Suppression
systems w/ FM-200™ agent. This document has been revised to incorporate the latest design requirements
found in NFPA Standard 2001, as well as the most up-to-date information available for our products.
This manual has been provided for those individuals that are responsible for the design, installation, and/or
maintenance of Fike Clean Agent Fire Suppression systems. Others such as architects, engineers, sales and
marketing personnel, etc. will find the information herein useful as well.
Fike offers two concepts of system design that are described within the following chapters.
1. Pre-Engineered Systems – These are simple “boilerplate” systems that operate within a pre-
determined set of criteria as tested and approved by Underwriters Laboratories Inc. These systems
do not require the designer to perform a complicated set of hydraulic flow calculations and they are
intended to provide a fast, easy means of designing systems.
2. Engineered Systems – These are the more complicated, elaborate systems that operate within a less
restrictive set of criteria as tested and approved by Underwriters Laboratories Inc. These systems
are designed within the basic parameters outlined in this manual, and their performance is evaluated
with the assistance of the Fike Flow Calculation Program.
Tests have shown that the Fike Flow Calculation Program can accurately determine the expected
performance of the Clean Agent Fire Suppression system when it is discharged. This provides the
system designer with the maximum degree of flexibility possible as it pertains to flow imbalance, tee
splits, piping configurations, etc.
Fike Clean Agent Fire Suppression systems must be installed and maintained in accordance with the limitations
established NFPA Standard no. 2001, Clean Agent Extinguishing Systems, as well as the limitations set forth by
Underwriters Laboratories Inc. The information contained within this manual defines these limitations in detail.
Enough information is incorporated into this manual to allow those responsible for designing Fike Clean Agent
Fire Suppression systems to properly do so, and for the parties responsible for verifying the system design to
determine if the design parameters have in deed been met.
The data contained within this manual is provided for informational purposes only. Fike believes this data to be
accurate; however, all dimensions are approximate and this document is presented without any guarantee or
warranty whatsoever.
Any questions concerning the information presented in this manual should be addressed to:

FM 3010715 Manual P/N: 06-215 (Rev G) Revision Date: January, 2010
This section covers the hardware utilized by Fike Clean Agent Fire Suppression Systems, including the optional
items that are available. All of the information contained herein is believed to be accurate and up-to-date.
However, it should be noted that all dimensions shown are approximate and Fike reserves the right to make
adjustments as necessary.
1.1 AGENT
The extinguishing agent used in Fike Suppression Systems is Heptafluoropropane – more commonly known by its
ASHRAE designation: HFC-227ea. HFC-227ea is a colorless, odorless, liquefied compressed gas. (See the
Physical Properties Table below.) It is stored as a liquid, but dispensed into the hazard as a colorless,
electrically-nonconductive, gaseous vapor due to its relatively low boiling point. HFC-227ea has been tested and
verified to be safe for use in occupied spaces when used as specified in the U.S. EPA Significant New Alternative
Policy (SNAP) rules. Tests have proven that exposure to HFC-227ea is safe and effective in extinguishing fires at
low concentrations; most of which are well below the EPA’s maximum exposure levels. HFC- 227ea is approved
for use in occupied areas up to a 10.5% concentration by volume with mandated egress time of five (5) minutes.
1.2 PERFORMANCE
HFC-227ea’s mechanism of extinguishing fires is considered active. Its primary action is through physically
cooling the fire at the molecular level. HFC-227ea belongs to the same class of agents used in refrigeration and
as such, is an efficient heat transfer agent. HFC-227ea removes the thermal energy from the fire to the extent
where the combustion reaction cannot sustain itself. Additionally, there is a chemical action that provides a
secondary means of extinguishing the fire. Trace amounts of free radicals are released into the fire – thereby
inhibiting the chain reaction of combustion. HFC-227ea does not significantly reduce oxygen levels and is safe
for use in occupied spaces in accordance with the U.S. EPA guidelines. HFC-227ea can be removed from the
protected space by simple means of ventilation after discharge.

1.4 USE AND LIMITATIONS
Fike HFC-227ea Systems must be designed and installed in accordance with the requirements outlined in this
manual, and in accordance with the requirements of the Standard for Clean Agent Extinguishing Systems, NFPA
2001, latest edition. HFC-227ea systems are primarily used to protect hazards that are enclosed; this provides a
means to establish and maintain an effective extinguishing concentration. Typical hazards that can be protected
include the following.
Electrical and electronic hazards
Telecommunications facilities
Storage Rooms – Flammable liquids and gases
High value assets, where the associated down-time would be costly
HFC-227ea systems shall NOT be used on fires involving the following materials.
Chemicals or mixtures of chemicals which are capable of rapid oxidation in the absence of air. Examples
include Cellulose Nitrate and Gunpowder.
Reactive metals such as Lithium, Sodium, Potassium, Magnesium, Titanium, Zirconium, Uranium, and
Plutonium
Metal hydrides such as Sodium Hydride and Lithium Aluminum Hydride
Chemicals capable of undergoing auto thermal decomposition. Examples include Organic Peroxides and
Hydrazine.
1.4.1 EXPOSURE
Although HFC-227ea is considered to be non-toxic, the EPA has established the guidelines controlling the
amount (concentration) of agent provided for the protected area. Based on PBPK modeling, the EPA allows
HFC-227ea for use where people are normally present (normally occupied spaces) up to concentration of 10.5%
by volume with exposure limited to 5 minutes or less.
WARNING: The discharge of clean agent systems to extinguish a fire can result in potential hazard to
personnel from the natural form of the clean agent or from the products of combustion that result
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.. The requirement for
pre-discharge alarms and time delays are intended to prevent unnecessary exposure to humans
where their presence is not critical to the operation of the area being protected. Suitable
safeguards shall be provided to ensure prompt evacuation of (and prevent entry into) protected
areas after discharge.
1.4.2 EXPOSURE LIMITS
HFC-227ea systems provided for Normally Occupied Spaces can be designed for concentrations above to the
NOAEL level of 9% by volume, given that means be provided to limit exposure to design concentrations shown in
Table 1.4 that correspond to a maximum permitted human exposure time of five (5) minutes.
HFC-227ea
Concentration ppm Human Exposure Time (minutes)
9.0% 90,000 5.00
9.5% 95,000 5.00
10.0% 100,000 5.00
10.5% 105,000 5.00
11.0% 110,000 1.13
11.5% 115,000 0.60

HFC-227ea systems provided for Normally Non-Occupied Spaces can be designed for concentrations in
excess of the LOAEL concentration of 10.5%. Where a possibility exists for personnel to be exposed, means
shall be provided to limit exposure times in accordance with the above table. In the absence of the information
needed to fulfill the conditions listed above, the following provisions shall apply.
Where egress takes longer than 30 seconds but less than 1 minute, the HFC-227ea system shall not
be designed for a concentration exceeding the LOAEL of 10.5% by volume.
Where egress takes less than 30 seconds, the HFC-227ea system can be designed for a
concentration that exceeds the LOAEL of 10.5% by volume.
1.4.3 TOXICITY
With a database in excess of 70 toxicity tests, HFC-227ea has been extensively tested and approved by
institutions and agencies around the world. The LC50 toxicity rating for HFC-227ea is greater than 800,000 ppm.
When you consider that most HFC-227ea systems are designed for concentrations providing 105,000 ppm or
less, it is evident that HFC- 227ea is safe to use.
HFC-227ea will decompose to form halogen acids when exposed to extremely high temperatures. The formation
of these acids is minimized by using fast-acting Fike detection and control systems, and proper system design
and installation of the piping system to deliver the agent quickly. The generation of by-products from the HFC-
227ea discharge will be minimal when properly applied.
1.4.4 NOISE
The high-pressure discharge from the nozzle(s) of a system can cause noise that is loud enough to be startling,
but ordinarily insufficient to cause traumatic injury.
1.4.5 TURBULENCE
The high velocity discharge from the nozzle(s) can be sufficient enough to dislodge substantial objects located
directly in the discharge path. Enough general turbulence may be created within the enclosure to move
unsecured paper and light objects.
1.4.6 1.4.6 CHILLING
Direct contact with the vaporizing agent being discharged from the nozzle(s) will have a chilling effect on objects
and can cause cryogenic burns to the skin. The liquid phase vaporizes rapidly when mixed with air, thus limiting
the hazard to the immediate vicinity of the discharge nozzle.
1.4.7 VISIBILITY
Although HFC-227ea is odorless, discharging the agent into a humid atmosphere may cause a reduction in
visibility for a brief period of time due to condensation of water vapor normally present in the room atmosphere.
1.4.8 PRESSURE
The normal operating pressure of a Fike HFC-227ea clean agent extinguishing system unit is 360 psig @ 70oF
(24.8 bar @21oC). This is accomplished by adding a charge of nitrogen to the HFC-227ea agent. Since these
are pressurized vessels, care must be observed when handling, filling and transporting storage containers. The
anti-recoil devices (baffle plugs or baffle plates) MUST be in place whenever the charged container is removed
from the piping network.

1.5 AGENT STORAGE CONTAINERS
The Agent Storage Container is a steel pressure vessel designed to hold the HFC-227ea under pressure until it is
discharged. All Fike HFC-227ea Containers are suitable for use at storage temperatures of +32oF to +130oF (0oC
to 54.4oC). Each container is manufactured in strict accordance with Department of Transportation / Transport
Canada (DOT / TC) regulations and undergoes extensive pressure and leak testing before shipment to the field.
All Fike HFC-227ea Containers are shipped from the factory fitted with an anti-recoil device installed in the
discharge valve outlet – in accordance with DOT / TC requirements. The anti-recoil device ensures the contents
of the pressurized container will be released in a slow, controlled, rate of discharge if the valve is opened during
the shipping and handling process. HFC-227ea Containers are filled with agent within the allowable range of 40
lbs/ft3to 70 lbs./ft3(640 kg/m3to 1121 kg/m3) of container volume in accordance with DOT / TC requirements. All
containers are filled in 1 lb. (0.5 kg) increments to the user-specified level defined for each container. Each HFC-
227ea container is super-pressurized with dry nitrogen to a working pressure of 360 psig at 70oF (24.8 bar at
21oC) after filling. Fike HFC-227ea Containers are available in twelve different sizes (capacities). Each container
includes a discharge outlet valve, fill valve, pressure gauge, mounting bracket or mounting strap(s), agent release
module, and provisions for the accessories available for that particular container size and/or style.
The Discharge Outlet Valve is a rupture disc (metal diaphram), pressure operated device that allows the agent to
be released from the container and into the protected space via the associated piping network and nozzle(s). The
Discharge Outlet Valve can be either welded or threaded to the Agent Storage Container (except for the 125i &
215i containers available with welded valves only).
Activation of the Discharge Outlet Valve is accomplished by one of two methods.
Standard operation of the valve is accomplished by a Gas Cartridge Actuator (GCA) that produces
the pressure wave (energy) necessary to open the valve. The GCA is an electrically operated device
that is activated by a signal from the control panel or the optional manual actuator device.
If the contents of the container are subjected to temperatures exceeding 160oF (71oC), the pressure
associated with the thermal expansion of the agent will be sufficient to open the valve automatically.
NOTE: The Discharge Valve also fulfills the pressure relief valve requirements in accordance with DOT
regulations.
NOTE: Containers manufactured by Fike for use with HFC-227ea to DOT 4BA requirements can be found in
Appendix B.
1.5.1 RUPTURE DISC
The Rupture Disc is the heart of the Fike HFC-227ea Discharge Outlet Valve. Each is manufactured to exacting
tolerances and standards by Fike to ensure their reliability and performance. The Rupture Disc is a pre-scored
metal membrane formed into a domed shape and scored with four pressure-relief lines across the domed surface
at right angles to each other. When the pressure in the container rises to the pre-determined level, the rupture
disc will open along the score lines – thus allowing the contents to be released into the piping network. The four
segments of the rupture disc “fold back” during discharge to produce the minimum amount of flow restriction
possible.
