Fike’s Equipment, Design and Service Manuals for Clean Agent Fire Suppression Systems incorporates 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 provides the information necessary for the design, installation, and/or maintenance of Fike
hardware and systems.
Fike utilizes two types of systems:
“Pre-Engineered System” concept – minimizes the engineering effort required to design an effective system. As
long as nozzle selection, pipe size and pipe length limitations are adhered to, hydraulic flow calculations are not
required.
“Engineered System” concept – 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 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. and FM Approvals. 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.
Any questions concerning the information presented in this manual should be addressed to:

CLEAN AGENT – HFC-125
EXTINGUISHING METHOD – HFC-125
HFC-125 extinguishes a fire primarily through Heat Absorption that occurs as the agent changes from a liquid to a
vapor during discharge. In addition, HFC-125 also disrupts the combustion reaction which aids in the
extinguishment of a fire. It is important to note, HFC-125 does not use the depletion of oxygen to extinguish a
fire.

OPTIONAL ITEMS FOR CONTAINER
The following container accessory items must be ordered separately.
ACTUATION COMPONENTS
• Electric / Manual Actuation – Impulse Valve
Operator (IVO) (For detailed information, refer to the
IVO Component Sheet p/n 06-432-1-5)
• Pneumatic Actuation – Impulse Valve Pneumatic
Operator (IVPO) (For detailed information, refer to the
IVPO Component Sheet p/n 06-432-1-6)
ACTUATION METHODS
Clean Agent containers with an Impulse Valve can be actuated by the following methods:
• Method 1 – Electric Actuation – Single Container System w/ IVO & IRM
• Method 2 – Electric Actuation – Multi-Containers System w / IVO & IRM
• Method 3 – Electric & Pneumatic Actuation – Two Container System w/ IVO & IVPO
• Method 4 – Electric & Pneumatic Actuation – Multi Container System w/ IVO & IVPO
For detailed information on actuation methods, refer to the Impulse Valve Operator (IVO) Component Sheet (p/n
06-432-1-5).
These devices provide the force required to extend a pin that will open the rupture disc, allowing the agent to be
released from the container.
LOW PRESSURE SWITCH
The Low Pressure Switch provides a means to continuously
monitoring the container pressure for a low-pressure condition.
If the pressure inside the container drops below 288 psig (1986
kPa), the switch contacts will transfer and invoke a “trouble”
indication on the control panel.
The Low Pressure Switch (P/N 02-12533) has a single pole,
double-throw switch that can be wired for normally open or
normally closed.
For detailed information, refer to the Low Pressure Switch
Component Sheet (p/n 06-432-1-3).

INSTALLATION
The system installation must comply with the requirements of this manual; NFPA 2001, latest edition; all
applicable local codes, regulations, and standards and the authority having jurisdiction (AHJ).
WARNING: DO NOT start system installation until the final design of the total system has been verified using
Fike’s Engineered Flow Calculation.
WARNING: The Actuator shall always be the last component installed on a Fike Clean Agent Fire
Suppression system to avoid accidental discharge.
FACTORS TO CONSIDER – CONTAINER LOCATION
FACTOR CONSIDERATION
MOUNTING
SURFACE
Container brackets must be mounted securely to solid load-bearing surfaces that will
support the container load.
Some installations may require additional mounting support not supplied by Fike.
ENVIRONMENTAL
EFFECTS
Container(s) should be located in clean, dry, and relatively vibration-free areas.
Avoid aisle ways and other high traffic areas where physical damage or tampering is more
likely.
Container(s) should never be mounted where the container could potentially be splashed
with, or submerged in any liquid.
Do not locate containers where they would be subject to physical damage, exposure to
corrosive chemicals, or harsh weather conditions.
TEMPERATURE
RANGE
Container locations must be between 32o
F (0o
C) to 120o
F (48.9o
C)
Temperatures outside of this range may result in the system not supplying the desired
quantity of agent or accidental discharge.
SERVICEABILITY
In general, the larger the container, the more difficult it will be to remove it from the system
for maintenance and service.
However, smaller containers that are located in a sub-floor space, under a computer bank,
or above the ceiling over the same computer bank can be difficult as well.
FLOOR SPACE
Consideration should be given to the space available to install the container(s).
For example, a 900 lb. (408 kg) system could be stored in (2) 650 lb. (267 L) containers
located on the floor.
However, if floor space is a problem, the system could be designed to utilize (6) 150i lb.
(61 L) Inverted Containers mounted on the wall(s).

th
FACTOR CONSIDERATION
FLOOR LOADING
Floor loading must be considered when selecting a container location.
The floor must be able to support the total weight of the Fike container(s) as they are
moved into position. Consult raised floor manufacturer for floor loading limitation.
The following guidelines are recommended:
Raised floor loading is a function of the manufacturer’s load specification and the
positioning of the container(s) on the raised floor grid.
NOTE: Fike cannot assume responsibility for determining the suitability of a particular
raised floor system; the following does provide information to help determine installation
requirements.
When clean agent containers are located on a raised floor, floor integrity must be
considered to determine if the type of tile and vertical floor support can handle the
increased load. If necessary additional floor supports can be added.
Option:
To help distribute the container weight over a greater area, a ¼” steel plate can be placed
under the container(s), sized to span multiple floor supports. If container spans multiple
floor tiles, add additional floor supports (Minimum of 4 floor supports, 1 per corner, must
be used). Excessive floor loading may require relocating the container(s) to a more
suitable location.
For floor loading information refer to Table 1 or to Fike’s ECARO-25 Flow Calculation
program for container size and actual fill weight being supplied.
NOTES:
1) Total Container weight is based on container tare weight + maximum fill weight.
2) Total Container weight + 22.5 lbs. (10.2 kg) added for 1/4" x 2' x 2' (6.4mm x 0.6m x 0.6m) plate used to
calculate Container w/ plate floor loading.

PRESSURE GAUGE – HFC-125
COMPONENT SHEET
Fike
®
, 704 SW 10
th
All Fike Clean Agent Fire Suppression containers w/ HFC-125 agent are
provided with a pressure gauge (p/n 02-10279) to indicate the internal
container pressure.
The pressure gauge scale is calibrated to show the actual pressure and is
color-coded to show operating range, under-pressure range, and over-
pressure range.
This gauge can be removed/replaced on a charged container without
removing the agent first. This port works by allowing a small controlled
amount of leakage past its internal threads. This provides enough flow to
operate the pressure gauge while being small enough to allow the gauge to
be removed safety.
Listings and Approvals UL Listed and FM Approved
INSTALLATION
The pressure gauge is installed on the container at the factory before the
container is filled / shipped.
The container pressure is checked as a part on the installation procedure. The gauge should read 360 PSIG at
70o
F (24.8 bar at 21o
C). For temperatures other than 70o
F (21o
C), reference Figure 1 – Temperature vs.
Pressure Chart.

REPLACEMENT PROCEDURE
The following procedure is used to replace the pressure gauge on a charged container.
CAUTION: When replacing a pressure gauge, do not allow the pressure port to remain open (disconnected)
for an extended period of time. A significant quantity of agent could be lost from the container.
Step Procedure
1
Place Teflon tape on the male thread connection of the replacement pressure gauge(s).
DO NOT overlap the end of the connection – the first thread should be uncovered.
2 Remove the old pressure gauge.
3 Install the new pressure gauge.
4 Check the assembly for leaks using a suitable leak test device.
NOTE: Refer to the Recharge Manual for recommendations and leak test procedures.

th
The Liquid Level Indicator (LLi) provides a means of verifying the weight of agent in a container without having to
remove the container and weigh it on a calibrated scale.
This device enables the inspector to determine the weight of agent with the container safely secured in its
installed position.
LLi’s are furnished on the 100, 150, 215, 375, 650 and 1000 lb. (44, 61, 88, 153, 267 and 423 L) containers.

th
Fike offers an optional Low Pressure Switch (LPS) for the
purpose of continuously monitoring the container pressure for a
low-pressure condition.
If the pressure inside the container drops below 288 psig (1986
kPa), the switch contacts will transfer and invoke a
“supervisory” indication on the control panel.
The LPS is an optional item and must be ordered separately.
This device is installed in the fill port on the container with an
Impulse Valve.
The LPS can be installed when the container is charged without
the concern of agent / pressure loss.

INSTALLATION
The LPS is an optional item and must be ordered separately. This device can be installed in the Fill Port on a
container that is charged by using the following steps:
Step 1: Prior to Assembly; lubricate the LPS O-Ring with Molycoat 55 or equal. Use care not to get lubricant into
pressure port.
NOTES: DO NOT apply Teflon Tape to LPS threads.
DO NOT cross thread the LPS during installation.
Step 2: Remove and retain Plug from Fill Port. (see Figure 1)
Step 3: Remove rubber cap and screw in the LPS (Hand Tight) until the switch bottoms out. Screwing the switch
in to this point will open an internal check valve and applies pressure the switch.
NOTE: “NO TOOLS” are required to install LPS.
Step 4: Leak check around the pressure gauge port using Snoop leak test fluid or equivalent.
If a leak is detected; remove the LPS from the fill port and remove the lubricant and contaminants from
the O-Ring, threads and valve port using isopropyl alcohol and a soft clean cloth. Lubricate the O-Ring
with Molycoat 55 or equal and reinstall. Leak test around the fill port.
If a leak is detected; remove the LPS from the fill port, remove the O-Ring, install a new O-Ring, lubricate
the O-ring with Molycoat 55 or equal, install the LPS in the fill port, and leak test around the fill port.
NOTE: When installing conduct connector to LPS
secure “Hand Tight”. Over tightening may
cause damage to the LPS or to the
Impulse valve fill port threads.
WIRING DIAGRAM – LOW PRESSURE SWITCH
The LPS should be wired into a supervised circuit in the control panel used to provide a supervisory signal if the
container pressure drops below 288 psig (1986 kPa). The switch is wired as a normally closed contact (open
under pressure). (see Figure 2)
NOTE: Refer to the Installation, Operation & Maintenance for the control panel being used for specific wiring
criteria.

The function of the Fike discharge nozzle is to control the agent flow and distribute the agent throughout the
protected enclosure in a uniform, predetermined pattern and concentration.
The discharge nozzle size refers to the size of schedule 40 or 80 pipe that it can be connected to.
The discharge nozzle is mounted to allow the agent to be discharge on a horizontal axis.
The nozzle orifice area is determined be performing a hydraulic calculation using the Fike Engineered Flow
Calculation program.
Nozzle should not be ordered until the clean agent system pipe network is installed and an “As Built” hydraulic
calculation is performed.
Nozzle orifice drilling must be done at Fike factory, or at a UL listed nozzle drill station.

ENCLOSURE VOLUME
FORMULA NOTES
Protected Volume = As a general rule, Hazard Volume should be based on the empty (gross) volume.
Base Volume Length x Width x Height
+ Added Volume
Volume that is open to the space being protected (i.e. non-dampered ductwork,
uncloseable openings, etc.)
- Removed Volume
Volume for items that are solid, non-permeable, and non-removable objects can be
deducted from the protected volume
IMPORTANT NOTE:
Any object that can be removed from the protected space CANNOT be deducted
from the volume
AGENT REQUIRED
Calculation Based on: Lowest Expected Ambient Temperature
Minimum Design Concentration Required
(to protect this type of hazard)
The agent quantity needed can be determined by the following formula:
Where: W = Agent Weight in lbs. (kg)
V = Hazard Volume / ft3
(m3
)
C = Design Concentration, % by volume
S = Specific Vapor in ft3
/lb (m3
/kg)
S = k1 + k2 (t)
Where: k1 = 2.7500, k2 = 0.0064(t), t = temperature (o
F)
or k1 = 0.1825, k2 = 0.0007(t), t = temperature (o
C)
NOTE: The equation to calculate S is an approximation.

TEE DESIGN FACTOR
Definition:
When a single agent supply is being used to protect multiple hazards, a tee design factor is
applied when more than 4 tees are used in multiple hazard applications.
Steps:
Tee
Count
Design
Factor
1
Starting from the point where the piping enters the hazard that is located
farthest (hydraulically) from the agent container(s), count the number of tees in
the direct flow path as it returns to the agent container(s).
Do Not include the tees that are used in the manifold (if applicable).
0 – 4 0.00
5 0.01
6 0.02
7 0.03
8 0.04
2
Any tee within the hazard that supplies agent to another hazard shall be
included in the tee count.
9 0.05
10 0.06
3
After counting the tees, compare that number to the chart above to determine
the Tee Design Factor
11 - 12 0.07
13 0.08
14 - 15 0.09
4
Apply the Tee Design Factor to the Agent Quantity calculations by multiplying
the Tee Design Factor by the amount of agent previously determined in the
volumetric calculations
16 0.10
17 - 18 0.11
19 0.12
EXAMPLE:
This example shows a multi-hazard area arrangement. Starting at the point where the piping enters the hazard
farthest away, count the number of tees leading back to the agent container. With a tee count of five (5), an
additional 1% (0.01) of agent is required. Therefore, the base quantity of agent is multiplied by 1.01 (1%) to
determine the adjusted quantity of agent required
NOTE: Fike recommends increasing the design concentration to 8.9% for Class A or 9.2% for Class C when
protecting multiple hazards w/ single agent supply. This will satisfy the tee design factor requirement.

NOTE: The ECARO-25 flow calculation program will automatically calculate the agent required based altitude
correction factor entered
CONCENTRATION AT MAXIMUM TEMPERATURE
The expected concentration at maximum temperature can be determined by following formula:
100WS
C = ----------
V + WS
Where: W = Agent Weight in lbs. (kg)
V = Hazard Volume / ft3
(m3
)
C = Design Concentration, % by volume
S = Specific Vapor in ft3
/lb (m3
/kg)
Refer to Flooding Factor Table on page 3 to determine the S value
NOTE: This is a necessary step to properly evaluate the exposure and egress time limitations discussed in the
beginning of this section.
The ECARO-25 flow calculation program will automatically calculate concentration at the maximum
temperature entered.
