INTRODUCTION
This manual has been prepared primarily for the use of
Designers/Installers of IG-541 (iFLOW®) Fire Suppression
Equipment. Its purpose is to provide general information on
iFLOW® and its use in Fire Fighting systems and to give more
detailed information covering the design, installation, testing
and servicing of these systems.
Note:
The manual covers the minimum requirements for the
design of Total Flooding Systems. Local application
and explosion suppression systems are not covered by
the manual. Whilst marine and inerting systems are
not specifically excluded these applications require
additional considerations. If in doubt refer to the Product
Manager. If a total flooding system is not designed and
installed to the parameters set out in this manual Tyco
Fire Protection Products cannot guarantee the correct
operation of the system.
This manual has been prepared in the light of the best
information available at the time of publication. It has
been assumed that users of this manual have sufficient
experience of Fixed Fire Fighting Systems to enable the
correct interpretation to be made of the contents.
It must be recognised that correct system design, installation
and maintenance are fundamental to the safe and effective use
of any gaseous Fire Fighting System.
1.1
APPROVALS
The iFLOW® IG-541 system is based on a number of
components which have been approved or listed by VdS in
Germany.
1.1.1 TEMPERATURE RANGE
The components are designed and tested to operate in the
temperature range -20°C to 50°C or as stated in separate
component listings.
1.2
GENERAL INFORMATION
IG-541 has been introduced as an alternative to Halon 1301,
production of which ceased at the end of 1993, under the agreed
adjustments made to the Montreal Protocol in November 1992.
IG-541 is a mixture of three naturally occurring gases that
do not support combustion, nor have an impact on the ozone
layer, and has no greenhouse effect.
The three gases, Nitrogen, Argon and Carbon Dioxide are mixed
in the following proportions:
Nitrogen
Argon
Carbon Dioxide
52%
40%
8%
IG-541 storage containers are designed to hold IG-541 in
gaseous form at a nominal pressure of 200 bar or 300 bar at
15°C.
Handling and Installation of IG-541 equipment should only be
carried out by persons experienced in dealing with this type of
equipment.
1.3
DESCRIPTION OF IG-541 SYSTEMS
IG-541 systems are designed to extinguish fires involving
flammable liquids, gases and class A hazards, especially
electrical equipment.
The systems are designed to be total flooding and consist of
a fixed supply of IG-541 connected to a piping system with
nozzles to direct the agent into an enclosed hazard. IG-541
extinguishes fires by lowering the oxygen content below the
level that supports combustion. In simple terms if the oxygen
content of the atmosphere is reduced to a level below 15%,
most ordinary combustibles will not burn.
As an example an IG-541 system will reduce the oxygen
content from 20.9% to approximately 12.5% whilst increasing
the carbon dioxide content from 0.03% to around 3%. The
increase in carbon dioxide content increases an individual’s
respiration rate and the body’s ability to absorb oxygen thus
allowing the body to compensate for the lower oxygen content.
Since IG-541 is stored as a gas, it discharges as an invisible
gas, allowing people to safely exit a protected space without
obscured vision.
IG-541 systems are particularly valuable in extinguishing fires
in enclosures containing hazards or equipment where a clean,
electrically non-conductive medium is essential or where the
cleaning up of foam, water or powder would be problematic.

SAFETY OF INERGEN
GENERAL
INERGEN simultaneously reduces the oxygen
concentration in an enclosure and increases the carbon
dioxide concentration. Proper and safe INERGEN design
requires that the design concentration falls within a design
window that limits the upper and lower concentrations of
oxygen and carbon dioxide. INERGEN has been accepted
for use in occupied spaces when the design concentration
falls within this window.

DATE:
1.5.3 NOISE
Discharge of an IG-541 system can cause noise loud enough
to be startling but ordinarily insufficient to cause traumatic
injury.
1.5.4 TURBULENCE
High velocity discharge from nozzles may be sufficient
to dislodge substantial objects directly in the path of the
discharge. General turbulence in the enclosure may be
sufficient to move light objects, unsecured paper etc. Ceiling
tiles in the vicinity of the nozzles should be clipped in place to
prevent them being dislodged during the discharge.
1.5.5 VISIBILITY
Under normal conditions IG-541 will not reduce visibility in
the protected enclosure. However in a fire situation especially
where large amounts of smoke are produced it is likely that
the IG-541 discharge will produce some displacement of that
smoke around the enclosure and this could reduce visibility in
some circumstances
1.5.6 EXITS
Adequate means of escape from the protected area should be
provided. Doors should open outwards and be self closing.
They should be arranged to open easily from inside and any
that need to be secured must be fitted with escape overrides.
1.5.7 POST DISCHARGE VENTILATION
In order to allow for the ventilation of IG-541 and/or the post
fire atmosphere, a normally closed means of ventilation with
extract arrangements will be required as with any gaseous
extinguishing system. Any mechanical ventilation provided
should not form part of the normal ventilation system. Controls
for the ventilation system should be outside the protected
enclosure and should be key operated. In some circumstances
the normally closed means of ventilation may be provided by
doors and windows.
1.5.8 ODOURISERS
If considered appropriate to give a warning as to the
presence of IG-541 in, or adjacent a protected space an
odouriser may be added into the system pipework.

For application in fire extinguishing systems, the IG-541
quantity is mainly designed to create oxygen concentrations
between 10% and 15% and CO2 concentrations between 2%
and 5% and no hazards are known for the healthy human
during short exposure in this atmosphere. However the
combustion products from the fire itself could be highly
toxic, therefore people shall always leave the room when it is
flooded with IG-541.

SYSTEM DESIGN
2.1
DESIGN STANDARDS
Information contained in this manual has been based generally
on the ISO 14520 Standard on Gaseous Fire Extinguishing
Systems and also EN15004 Fixed Firefighting Systems.
The manual has been prepared to give an understanding in the
application of IG-541 systems. Systems are suitable only for
the total flooding of hazard enclosures.
2.2
DETERMINATION OF IG-541 QUANTITY
Prior to commencing with the design of any IG-541 system,
the designer should have, as a minimum the following details:
i) Enclosure dimensions
ii) Specific details of the hazard, such as fuel types,
chemicals, excessive fire load, etc.
iii) The minimum and maximum temperatures of
the hazard enclosure
iv) Height of the enclosure above (or below) sea
level
v) Confirmation of the integrity of the protected
space
vi) Details of the ventilation system
vii) Intended occupancy of the enclosure
viii) Storage container location, (this should
preferably be outside the protected enclosure),
but must not be exposed to weather or other
potential hazards. Floor loading should also be
taken into account
ix) Details of National laws or requirements that
need to be taken into account, for example TRG
280, which is applicable in Germany.
The following notes provide additional information to assist
the designer in providing the correct system for the hazard.
IG-541 systems are suitable for the protection of hazards
involving Class A, B and C materials. Providing a Class A fire
is detected quickly and the IG-541 discharged promptly and
the concentration is maintained for an adequate period of time
to allow embers to cool, surface fire and embers associated
with the burning of solid materials are quickly extinguished.
IG-541 systems are suitable for use on fires involving live
electrical equipment but is not effective on, and should not be
used to fight fires involving:
1) Chemicals containing their own supply of

2)
3)
4)
5)
oxygen, such as cellulose nitrate.
Mixtures containing oxidising agents such as
sodium chlorate or sodium nitrate.
Chemicals capable of undergoing autothermal
decomposition such as some organic peroxides.
Reactive metals.
Solid materials in which fires quickly become
deep seated.
Class B and C fires are quickly extinguished by IG-541 at the
appropriate concentrations, but in the case of Class C fires the
risk of explosion should be carefully considered and where
possible the flammable gas flow should be isolated before or
as soon as possible after extinguishment.
Determine the gross room volume. The net volume can only
be considered if there are permanent impermeable building
structures within the area.
i) Establish the minimum anticipated temperature of the
protected enclosure.The IG-541 equipment may not be
used where the hazard temperature is below -20°C. The
system must be designed using the minimum design
temperature.
ii) Determine the minimum design concentration required
for the hazard involved. As IG-541 is released into an
enclosure it displaces air and some IG-541. Therefore
more IG-541 is injected into an enclosure than remains
when the discharge is completed. The proportion of air
that has been replaced by IG-541 when the discharge is
complete is called the design concentration.
The ratio of the volume of an enclosure to the volume of IG541 injected into it is called the flooding factor.
The relationship between the design concentration and the
flooding factor may be summarised by the following equations.
Design Concentration (dc)
Flooding Factor (ff)
= 100 - 100 / eff
= ln (100 / (100 - dc))
The minimum design concentration as specified by ISO 14520
for Surface class A, is 39.9% For electrical installations Tyco
Fire Protection Products recommends the use of a minimum
design concentration of 40% - flooding factor 0.51 at 20°C (m³
IG-541 / m³ protected space). Class B and C risks should be
given special consideration. Table 3 contains a list of various
materials and the appropriate minimum design concentration.
The values taken from ISO 14520 and are based on the
‘extinguishing value’ plus 30% and then rounded up to the
next nearest full number.EN15004 specifies the minimum
design concentration for surface class A as39.9% and 48.1%
for class B.The minimum design concentration for higher
hazard class A is 45.7%. In case of doubt, please refer to the
Product Manager.

iii) Multiply the gross volume by the appropriate flooding
factor from Table 4 or determine the agent quantity
required by using the formula:
Agent Quantity =
Where
V x (ln (100 / (100 - dc)) x
((0.70818 / (0.65799 + (0.00239 x t)))
dc = Design Concentration (% by volume)
V = Hazard volume (m³)
t = Design temperature in hazard volume (°C)
Note:
Adjust the agent quantity in accordance with Table 5 if
the system is to be installed at altitudes that vary from
sea level by more than 11%.
iv) Determine the number of IG-541 containers required

2.2.1 ACHIEVED IG-541 CONCENTRATION
2.2.3 EXTENDED DISCHARGE
The ‘Halon Alternatives Group’ report, ‘A review of the
toxic and asphyxiating hazards of clean agent replacements
for Halon 1301’, advises that IG-541 systems may be used in
the fully automatic mode in occupied areas where the oxygen
level does not reduce below 12% (flooding factor 0.56).
Should the nature of the hazard determine that an extended
discharge of IG-541 is required the system must be so
configured that the requirement for 95% of the ‘minimum’
design concentration for the hazard enclosure is achieved
within 1 minute.
In the event that the oxygen level is between 10% and 12%
(flooding factor 0.74 - 0.56), the system may be on automatic
providing the enclosure can be evacuated in less than 2
minutes.
If the oxygen level falls below 10% (flooding factor greater
than 0.74), the system must not be used in the automatic
mode whilst the enclosure is occupied.
In order to determine or confirm which of the above conditions
apply, the following steps should be taken.
i) Calculate the exact volume of IG-541 to be discharged
into the protected enclosure by multiplying the number
of containers to be provided by the volume of IG-541
contained in each (refer to Table 2).
ii) Divide the actual volume of IG-541 being provided by
the nett hazard volume to determine the actual flooding
factor.
iii) Correct the flooding factor calculated above for
temperature by dividing it by
0.70818 / (0.65799 + (0.00239 x t))
where t = maximum enclosure temperature.
iv) Relate the actual flooding factor to the conditions of
use outlined above.
2.2.2 DISCHARGE TIME TO ACHIEVE MINIMUM DESIGN
CONCENTRATION
Any extended discharge should be designed to add IG-541 at
such a rate as to compensate for losses. The duration of the
extended discharge may be determined according to the nature
of the hazard and the required hold time.
All extended discharge systems should be referred to the
Extinguishing Product Manager.
2.2.4 CONNECTED RESERVES
Connected reserves can be accommodated in the system.
The means to achieve this will normally be by means of a
duplicate bank of IG-541 containers connected into a common
manifold. All parts of the storage system will be duplicated
but the pipework system from the container storage area and
the discharge nozzles will normally be common.
2.2.5 STOP VALVES AND DISTRIBUTION VALVE SYSTEMS
Stop valves and distribution valves can be accommodated in
the system. Both types of arrangement will create ‘closed’
sections of pipework and will require pressure relieving
devices (pressure relief valves). The methodology by which to
achieve the many configurations possible will require the use
of non-return valves and pilot line bleed valves strategically
positioned in the pneumatic control system. An example of a
typical layout is shown in Fig. 1.
The ‘minimum’ design concentration is defined as the quantity
of IG-541 required to achieve a concentration not less than
the extinguishing value, plus a 30% safety factor, even if the
actual design concentration for the hazard enclosure is greater
than the ‘minimum’ value. For example, if the hazard consists
of combustible materials that are extinguished at 28.1% to
give a ‘minimum’ design concentration of 36.5% (say 37%)
but the actual design is based on 40% design concentration,
then the requirement is for 95% of the ‘minimum’ value (0.95
x 37%) i.e. 35.2% concentration to be discharged within 1
minute.
Expressed as an oxygen level the following calculation will
apply:
100% - 35.2% = 64.8% of start level.
Therefore (assuming initial oxygen level of 21%) - 64.8% of
21% = residual oxygen level of 13.7%.

iFLOW® IG-541 CONTAINER VALVES
3.2.1 300 BAR iFLOW® IG-541 CONTAINER VALVE
(Part No. 21114010)
The iFLOW® IG-541 300 bar container valve is a quick action
valve designed to be operated by means of a gas metron, local
manual actuator or pneumatic actuator.
All valves are provided with a recoil cap which is screwed
onto the IG-541 discharge outlet. This is removed only when
the container is to be connected into the pipework system and
must be refitted immediately the container is disconnected
from the pipework. (Regardless of whether the container is
full or empty).
When installed in a system the valve is to be fitted with
a pressure gauge (Part No. 42116056) to provide visual
indication of container pressure. As an optional item a gauge
fitted with electrical contacts (Part No. 42116057) may be
provided to enable an electrical indication to be given in the
event of a loss in container pressure exceeding 10%.
A safety burst disc is incorporated in the valve and is designed
to rupture at between 400 bar and 430 bar.
In the event that the safety burst disc ruptures IG-541 will be
discharged through the burst disc outlet adaptor. As a safety
precaution a recoil cap (supplied with all charged containers)
must be fitted to this outlet.

PNEUMATIC ACTUATOR
(Part No. 30116APB)
The pneumatic actuator can be installed on to the iFLOW®
valve. It comprises of an internal piston complete with firing
pin. Following acutation by pressure the firing pin moves
forward and ruptures a burst disc in the iFLOW® valve causing
it to operate. It can be fitted with up to three actuating hoses.
It is supplied with a ¼” blind cap which can be fitted to the
unit to blank off one of the inlets (if required by the container
bank configuration).
! CAUTION
Failure to reset the actuator prior to fitting onto the
container valve will result in the immediate operation of
the container valve and the potentially hazardous discharge
of the container.
The actuator requires a minimum pressure of 60 bar to cause
operation.

3.16 1/4” BLEED VALVE
(Part No. 20007020)
The bleed valve is used in the actuation line of systems where
an unintentional build-up of pressure, perhaps through a leak,
could be problematic.
The device will automatically relieve pressure caused by small
leaks but will seal to completely prevent loss of actuation
pressure when, typically, the pilot cylinder operates.
As an option on single risk system. This can be fitted on the
last pneumatic cone.

3.17 PILOT LINE NON RETURN VALVE
(Part No. 20006020)
The pilot line non return valve is used when there is a
requirement to either maintain pressure in a particular section
of the pilot line or to ensure that nitrogen pressure from the
pilot cylinder is operating the correct iFlow IG-541 containers.
For example, a system using distribution valves where
differing numbers of containers are required for each risk will
use the pilot line non return to ensure that pilot pressure opens
only the correct bank of containers and the correct selector
valve.
Various adaptors are available to fit the pilot line non return
valve and these are detailed in the installation section of this
manual.

The selector valve is used in applications where multiple areas
require to be protected from a single bank of containers.
The valves are pneumatically operated by a pilot cylinder (see
section 3.9).
The pressure enters through the top port (see figure 13) and
when the selector valve is fully open the contained pressure
exits through the bottom port. Pressure from the bottom port
is connected via a suitable pilot line to operate the appropriate
number of containers required to protect a particular risk.
A typical selector valve system is shown in figure 14.
The operation of a typical system is as follows:
The fire detection system in one of the protected risks operates.
A fire signal is sent to the solenoid on the pilot cylinder and it
operates. At the same time a signal operates a second solenoid
which is connected to the pilot line from the pilot cylinder.
This second solenoid opens and allows pilot cylinder pressure
to pass to the appropriate selector valve. The selector valve
piston operates and opens the selector valve. When the piston
is at its fullest travel the selector valve is fully open, pressure
then passes from a port in the bottom of the piston to the
container bank. This pressure operates the container bank and
IG-541 discharges through the selector valve into the risk.
A selector valve microswitch (Part No. 30116011) is available
and when fitted will electronically signal that the selector
valve has operated.
A lever to manually close the selector valve after operation is
also available (Part No. 20010013).

Table.19 Welded Nipple Part Numbers For Selector Valve Solenoid Manifolds
When ordering a selector valve manifold you select the appropriate
manifold from either Table 17 or Table 18. The diameter of the manifold
selected must not be smaller than the size of any of the required selector
valves. You then need to also order the correct size and number of
welded nipples from Table 19 one for each selector valve required to be
fitted to the Selector Valve Manifold.
For example if you require a 4” manifold suitable for five selector
valves of the following size; 1 x 4” selector valve , 2 x 3” selector
valves, 1 x 1 ½” selector valve and 1 x 1” selector valve ; you need to
order the following:
1 x P/N 36588888 4” Selector valve manifold (for 5 x selector valves)

3.20 iFLOW® MANIFOLDS
(Part No. as shown in table)
iFLOW® selector manifolds are designed to enable containers
in the iFLOW® container bank to be connected to the supply
pipe or to the selector valve manifold (when required).
They can be supplied with a galvanised finish if required (see
table 21). Normally a 10% sample of manifold is pressure
tested to 180 bar.
Iflow Manifolds are supplied with a NPT male thread at
each end.
They are not supplied capped at one end. If you wish to cap
one end of the manifold use appropriate NPT screwed fittings.
If you need to join any standard manifolds together for
a particular installation or container bank configuration,
manifold unions(as detailed in Table 23) are available.
You can also use the manifold union to connect the discharge
pipe work to the end of the manifold.

3.22 SAFETY DISC FOR MANIFOLD
(Part No. 200CD190)
The safety disc is designed to automatically relieve pressure in
the pipework system. It is normally fitted in all closed section
of pipework, i.e. between the container and stop valve, etc. It
has a disc that ruptures at 120 bar.
It is a requirement that the outlet from the safety disc is pipe to
atmosphere away from the personnel. A manual by-pass valve
must be incorporated into the pressure relief arrangements
to allow for trapped IG-541 to be safely vented away to
atmosphere.

pipework or nozzle positions to be made without the authority
of the Extinguishing Systems Design Engineer.
4.1
DELIVERY AND HANDLING OF EQUIPMENT
i)
ii)
Check all equipment delivered against the Delivery
Note. Notify the supplier immediately if there is any
discrepancy between the equipment received and
that indicated on the Delivery Note.
Store all equipment in a dry room at a temperature
between 0°C and 50°C and protect from direct
sunlight, until it is ready for installation. Keep
containers upright and secure them so that they
cannot fall over.
! CAUTION
Make no attempt to move iFLOW® containers unless they
are fitted with transport caps and anti-recoil caps.
iii) It is usual for, but not essential, for the installation
to start with the fitting of the containers. To move
iFLOW® containers use a trolley and if containers
are to be raised over steps etc; ensure that appropriate
lifting equipment is used. Under no circumstances
must containers be rolled or dropped into position.
! CAUTION
Until containers are fully connected into a completed
pipework system and secured by the container bracketing
the valve transport cap must not be removed.
PAGE 58 of 93
4.2
i)
CONTAINER FIXING
The container bank will be constructed to allow
fitting to wall/supporting structure.
ii) Check that there is at least 300mm free access at the ends
of the container bank, and at least 1000mm free access at
the front of the bank.
iii) Ensure that the floors and walls are flat.
iv) Matrix brackets can only be used with 80 litre
iFLOW® IG-541 containers and can only be wall
mounted. A maximum of four rows is permitted. The
container bank must be configured so that a maximum
of 4 x 80 litre iFLOW® containers flow through the
discharge hoses and check valves before connecting
to a manifold or to the discharge pipework . If a
manifold is required it is always fixed to the wall.
Various typical container bank configurations are
shown in the appendix to this manual. The general
instructions for Matrix brackets are shown in figure
18 below.
v) 140 litre container brackets are only available for
wall mounting. There are four types of brackets
single row two containers, single row three
containers, double row four containers and double
row six containers. A maximum of two rows is
permitted. The container bank must be configured so
that a maximum of 2 x 140 litre iFLOW® containers
flow through the discharge hoses and check valves
before either connecting to a manifold or to the
discharge pipework. If a manifold is required it is
always fixed to the wall. Various typical container
bank configurations are shown in the appendix to
this manual. The general instructions for 140 litre
brackets are:
Single Row (only suitable for 2 x 140 litre systems):
vi) Fit rear crosspiece brackets to the wall, the lower

DISCHARGE HOSE INSTALLATION
i)
ii)
The discharge hose has a fixed male thread one end
and a swivel female thread the other end.
There are two different types of hose available
one for 80 litre containers and one for 140 litre
containers. They are both of the same design and
only differ in their overall length.
iii) On the first container one side of the check valve is
sealed using a ¾” blind cap and a bonded seal. The
other side has male adaptor fitted to it.
iv) The male end of the discharge hose is screwed into
the second check valve and then the female swivel
end of the hose is attached to the male adaptor fitted
to the first check valve end (see Figure 23).
v) A dowty seal is also used to attach the male adaptor
to the check valve. No thread sealant is required
on any joints for the discharge hose/check valve
process.
vi) Repeat the connection steps for the remaining
containers.
vii) At the last container the final discharge hose is connected
either to a manifold or directly to the discharge pipework.
Note:
A maximum of 4 x 80 litre and 2 x 40 litre containers can
be connected this way. For large systems the container
bank needs to be configured to take this into account.

4.5.1 PILOT CYLINDER
The iFLOW® Container bank is normally operated by a
pilot cylinder. The pilot cylinder contains nitrogen at 100bar.
There are three sizes available 3 litre, 13litre and 50 litre. All
are supplied with a contacted pressure gauge, solenoid and
manual release. The contacted pressure gauge and solenoid
are factory fitted but the manual release is fitted on site. When
the pilot cylinder is operated pressure flows to the pneumatic
actuators fitted to the iFLOW® container valves.
Fix pilot cylinder bracket to the wall. Then fit the pilot cylinder
to its bracket and ensure that the pressure gauge is visible and
that the manual actuator is easily accessible. Remove the
pilot valve top cap when fitting the control pilot hoses and the
pneumatic actuators to the iFLOW® container valves. When
the pilot cylinder top cap is removed if the unit is accidentally
operated via one of its actuation devices the valve will not
open.
Fit the outlet adaptor to the outlet of the pilot cylinder valve
then fit the tee piece to the outlet adaptor.
From the tee piece you can fit either a pilot hose or an adaptor
to 6mm tubing. The bleed valve is fitted to the other port in
the tee piece.
All of these components are supplied with the pilot cylinder
and do not need to be ordered separately.
Note:

4.5.3 PRESSURE SWITCH WITH INTERLOCK
4.5.4 The pressure switch has two sets of contacts, normally open
and normally closed. The pressure switch may be used to
provide an electrical indication of the release of IG-541 or to
perform ventilation shutdowns or other interlock functions.
For iFLOW® systems using a manifold it is mounted on the
manifold. For iFLOW® systems not requiring manifolds it is
mounted on the coupling union used to connect the container
bank to the discharge pipe work.
i)
ii)
Apply a suitable pipe sealant to the threaded
connection. Do not apply pipe sealant to the two first
threads.
Tighten union with a suitable spanner.
iii) Electrical connections are detailed in the electrical
installation section of the manual (see section 4.7.1).
Note:
The pressure switch is reset after discharge by pulling
the knob on the side of the unit.
SELECTOR VALVE
Selector valves up to and including the 2” version have
threaded connections. Selector valves above 2” use welded
unions as pipe connections. They are connected between the
end of the discharge manifold and the discharge pipe system
for a particular risk.
Selector valve manifolds designed for use with the selector
valve are available. Alternatively manifolds can be fabricated
using special weldolets as specified in this manual.
i)
ii)
First fit the selector valve manifold to the end of the
discharge manifold then fit the selector valve to the
selector valve manifold.
If the selector valve has threaded outlets apply Teflon
tape (PTFE) to the male thread on the selector valve
manifold outlet. Do not apply Teflon (PTFE) tape to
the first two threads.
iii) Then attach the 6mm pneumatic actuation tubing to
the inlet of the selector valve pneumatic piston.
iv) Finally connect the 6mm pneumatic actuation tubing
to the outlet port of the pneumatic piston and run
the 6mm pneumatic actuation line to the container
bank to operate the appropriate number of iFLOW®
container for the risk.
Note:
The selector valve pneumatic piston pivots on its top
mounting during actuation and the 6mm pneumatic
actuation line needs to be able to flex to accomodate
this movement. Typically a “pigtail” (coil) in the
pneumatic actuation line is sufficient.

4.5.5 SELECTOR VALVE SOLENOID AND MANUAL RELEASE
Electrical and manual activation device to control the opening
of the selector valves. Brackets are available to mount 2, 3 or
4 selector valve solenoids. The inlet pressure to the selector
valve solenoid comes from the operation of the pilot cylinder.
The outlet pressure then opens the appropriate selector valve
once the solenoid on the selector valve solenoid is activated.
This component is supplied with the selector valve and does
not need to be ordered separately.
i)
ii)
Secure the bracket to the wall at an appropriate
height to enable easy manual actuation.
6mm actuation piping is used to connect the outlet
of the pilot cylinder to the inlet(s) of the selector
valve solenoid(s).
iii) 6mm actuation piping is then fitted between the
outlet of the selector valve solenoid and the inlet of
the appropriate selector valve pneumatic piston.
! CAUTION
It is essential to ensure that the pressure from the pilot
cylinder goes to the inlet part of the selector valve
solenoid. If accidentally fitted to the outlet the wrong
selector valve could operate when the pilot cylinder
discharges. The inlet is marked “1”, and the outlet is
marked “2”.

4.5.6 RELEASE SYSTEMS FOR SELECTOR VALVES
The fitting of selector valves to an iFLOW® IG-541 system
allows multiple risks to be protected from a single bank of
containers. Figure 31 shows a system where four containers
can be discharged into either one of two risks. If there is a fire
in Area 1 the selector valve needs to be operated and then the
four containers in the container bank need to be released. A
typical operating sequence is as follows:
i)
ii)
The fire detection system in area 1 activates and
sends a signal to the solenoid mounted on the pilot
cylinder. At the same time an electrical signal is also
sent to open the selector valve solenoid for Area 1.
The pilot cylinder operates and sends pressure
into the 6 mm actuation line and through the open
selector valve solenoid for Area 1.
iii) Pilot cylinder pressure from the outlet of the open
selector valve solenoid then flows to the inlet of the
selector valve actuation piston.
iv) This pressure operates the selector valve actuation
piston and opens the selector valve.
v) When the selector valve is fully open pilot line
pressure flows from the exhaust port of the selector
valve pneumatic piston and operates the containers
in the container bank.
Both the pilot cylinder and the selector valve solenoid are
fitted with manual releases to operate the system in the event
of an electrical failure. Figure 29 shows an installation where
an equal number of containers are required for each risk. The
system can be designed to operate any number of iFLOW®
containers to enable the protection of risks of un-equal size.
In these installations pilot line non-return valves are used to
control the number of containers discharged into a particular
risk.
The pilot line non return valve is normally installed with its
outlet fitted directly to the pneumatic actuator. It is therefore
supplied with an adaptor fitted to its outlet with the correct
male thread to fit directly to the pneumatic actuator. No pipe
sealant is required when fitted to the pneumatic actuator in
this manner. This is the preferred method of installing a pilot
line non return valve and the designer should always try to
configure the system in this manner.
However various adaptors are available to fit the pilot line non
return valve using pilot line hoses or 6mm o/d tubing if the
preferred method is not suitable.
The permitted variations to fit the pilot line non return valve
are detailed in this manual.
Note: ONLY THE CONFIGURATIONS SHOWN IN
THIS MANUAL AS THE PERMITTED VARIATIONS
TO FIT A NON RETURN VALVE CAN BE USED.
FAILURE TO USE THE SPECIFIED FITTINGS
MAY RESULT IN THE PILOT LINE NON RETURN
VALVE MALFUNCTIONING AND THEREFORE
CAUSING THE EXTINGUISHING SYSTEM TO
FAIL TO OPERATE.

SOLENOID VALVE
4.5.9
PNEUMATIC ACTUATOR
The solenoid valve is used to electrically operate the pilot
cylinder valve. When the coil is energised it opens the
solenoid valve and allows the pilot cylinder internal pressure
to open the pilot cylinder valve.
The pneumatic cone (1) comprises an internal piston (8) fitted
with firing pin (2). When the piston is pressurised by the
pilot cylinder it moves forward and the firing pin ruptures an
actuating disc in the iFLOW® valve causing it to operate.
The solenoid valve is supplied factory fitted to the pilot
cylinder. Do not electrically connect the unit until the system
is ready for commissioning.
The pneumatic cone has a pneumatic coupling attached to it
by a fixing screw (6). The pneumatic coupling has an inlet (4)
and an Outlet (5) to which pilot hoses may be attached. It is
also supplied with a ¼” blind cap to enable the outlet (5) to
be plugged.
! CAUTION
In the event of a fault with the solenoid valve return the
complete pilot cylinder to the OEM.
DO NOT ATTEMPT TO REMOVE THE SOLENOID
FROM THE PILOT CYLINDER ON SITE.
To assemble the Pneumatic cone 3 way to the iFLOW® valve
carry out the following steps:
i) Unscrew the fixing screw and separated the
Pneumatic cone from the pneumatic coupling.
ii) Fit the pneumatic cone to the iFLOW® valve using a
C-Spanner to each container in turn.
iii) Re-attach the pneumatic coupling to the pneumatic
cone using the fixing screw and tighten with a
suitable spanner. Fit the pilot hoses to the inlet and
outlet of the pneumatic coupling.
iv) On the last container to be pneumatically operated fit
the supplied ¼” blind cap to the pneumatic coupling
outlet port.
v) The unit is sealed by its O ring and no additional
sealant is required.
025334

! CAUTION
Before fitting the pneumatic cone to the iFLOW® valve
ensure that the operating pin is fully retracted by pushing
down with a screwdriver. The operating pin must not be
protruding from the pneumatic cone.

ACTUATION HOSE
¼” Diameter hoses fitted with brass swivel ends are used to
connect from the outlet of the pilot cylinder to the inlet of
the pneumatic cone on the first iFLOW® container and then
to interconnect between the remainder of the pneumatic
cones fitted to the other containers in the container bank. The
bending radius is 30mm. They are available in three different
lengths to suit various configurations of the container bank.
i) Firstly fit the actuation hoses between the pneumatic
cones fitted to the iFLOW® valve. It is recommended
not to connect the actuation hose between the pilot
cylinder and the first container in the container bank
until the system is being commissioned.
ii) For selector valve systems various fittings and nonreturn valves are available to configure the container
bank. For these systems reference must be made
to the installation drawings to enable the correct
configuration of the pneumatic actuation line.
iii) No sealant is required when fitting hoses to the
pneumatic cones.

ELECTRICAL INSTALLATION
Once the pneumatic actuation line is completed the various
electrical components can be electrically connected. It is
recommended that the top cap on the pilot cylinder valve is
removed while carrying out the electrical installation as then
if there is an accidental operation of the electrical solenoid the
pilot cylinder will not operate. The electrical connections for
the various components are described in this section.
4.6.1 PRESSURE SWITCH

If the pipe is more than 2 inches nominal bore (DN 50) and
the above distances cannot be adhered to the distance between
pipe fixings can be extended to up to 6 metres. However the
pipe fixing at each end of the pipe must then be doubled up.
Pipe fixings should be placed closely to elbows, tees, etc
where a change of the direction of the pipe takes place.
Pipe fixings should connect the pipe system directly to building
structure. Other pipes and services should not be supported
the system’s extinguishing pipe work. Care should be taken
to ensure that the area to which the pipe support is fixed to is
strong enough to take the load (see Figure 39 below).
The distance between the nozzle and its pipe fixing shall be as
short as possible.
For nozzle sizes 25mm and below the maximum
distance from the pipe fixing to the nozzle shall be
0.1 m.
For nozzle sizes above 25mm the maximum distance
from the pipe fixing to the nozzle shall be 0.25 m.
For pipe sizes up to 2” (DN50) support by 10mm steel studding
is recommended.
For pipe sizes above 2” (DN50) support by 12mm studding is
recommended.
PAGE 74 of 93
After installation of the pipe work and nozzles carry out a
purge of the pipework to remove any cutting oil or swarf in
the pipe system. Disconnect the containers from the manifold
fit any plugs as necessary and purge the pipe work with either
a hand held CO2 portable extinguisher or a nitrogen cylinder
fitted with a suitable pressure regulator.
In order to minimise dischage of oil and swarf it is
recommended to put bags over the nozzles to collect debris
If a purge of the pipework is not required or possible at
this stage, ensure that this is reported to the commissioning
engineer so that arrangements can be made for this to be done
at the commissioning stage.

DISCHARGE NOZZLE INSTALLATION
Nozzles consist of a diffuser body and an orofice. The orofice
is drilled to the size required by the iFLOW® design flow
program. The diffuser body is supplied with this drill size
(orifice) stamped in its body. The installation drawing will
indicate both the position of the nozzle and its drill size
(orifice).Each nozzle must be installed in the position indicated
in the installation drawing and must have the drill (orifice)
size indicated on the installation drawing.
! IMPORTANT
It is very important that nozzles are fastened securely that
they never point directly at ceiling tiles. Nozzles must
never be attached directly to the outlet of a container valve.
To fit the nozzle apply pipe sealing compound to the male
thread on a pipe or fitting ensuring that the first two threads
have no sealant. Then screw the nozzle on to the male thread
and tighten using a suitable wrench.

COMMISSIONING
This section provides guidance on the commissioning of
iFLOW® IG-541 Fire Extinguishing Systems and is in the
form of a check list to be completed by the person carrying out
the commissioning. The commissioning schedule (document
14 a-04-C1) is an addendum to this manual. It is intended to
cover the majority of the equipment and configurations likely
to be encountered, however, where appropriate it may be
necessary to carry out additional checks to those listed.
All sections must be completed, or if not applicable, write N/A
in the appropriate space.
It is essential that persons carrying out commissioning of IG541 systems are experienced in the commissioning of this type
of equipment.
Container pressures adjusted for temperature are to be checked
for compliance using Table 27, Page 81.
Pages 82 to 85 are an example of the schedule to be completed
by the responsible person. The schedule is to be completed
during the commissioning of all new systems and those that
have been modified.
5.1 PIPEWORK INTEGRITY

PNEUMATIC ACTUATION LINE TEST FOR
MULTI RISK AREA SYSTEMS
Remove all caps from the bank auxiliary iFLOW®
containers.
Disconnect the pilot line hose (or copper pipe) from the
outlet of the pilot cylinder.
Remove the coil from the solenoid on the pilot cylinder.
As follows in turn test the operation of each area’s selector
valve together with the pneumatic actuation line for the
number of iFLOW® containers designed to discharge into
this area.
Remove the pneumatic actuators from all of the iFlow
containers. Then remove the actuating piston from each
of the pneumatic actuators, turn it around and refit it to the
pneumatic actuator body with the piercing pin facing away
from the iFlow valve actuating disc. Refit the pneumatic
actuators to the iFlow container valves.
Attach a nitrogen cylinder which is fitted with a suitable
pressure regulator and pressure relief valve (see Figure
41) to the pilot hose that has been disconnected from the
pilot cylinder. Adjust the outlet pressure of the nitrogen
pressure regulator to 8-10 Bar and then open the valve on
the nitrogen cylinder to apply pressure to the pneumatic
actuation line.
Pressure from the nitrogen cylinder will pressurise the
actuation control piping up to the selector valve solenoids.
Check for leaks by applying a suitable leak detection spray
to all of the joints in the pneumatic actuation line from the
pilot cylinder to the selector valve solenoids.
At the Extinguishing Control Panel simulate a fire in a
particular risk area. This will send a signal to both the
solenoid for the pilot cylinder and also to the selector
valve solenoid for this area.
Check that the pilot cylinder solenoid’s coil is energised
(see Section 3.5 for details) by placing the end of a screw
driver inside the coil. There should be a magnetic force
felt on the screw driver to signify that the coil is energised.
Check that the correct selector valve solenoid has operated
causing the correct selector valve to open.
Check for leaks by applying a suitable leak detection spray
to all of the joints in the pneumatic actuation line from
the selector valve solenoid through the selector valve and
up through the pneumatic actuation line to the pneumatic
cones.
Close the valve on the nitrogen cylinder and vent the
pressure from the pneumatic actuation line.

following:.
xxi)
Remove the pneumatic actuators from all of the iFlow
valves. Remove the actuating pistons from the pneumatic
actuator and refit them in the body of the pneumatic
actuator with the piercing pin facing the iFlow valve
actuating disc. Reset the pistons in the pneumatic actuator
by pushing them fully into the actuator body using a screw
driver (see Figure 42)
xxii) Refit pneumatic actuators to the iFlow container valves.
xxiii) Disconnect the nitrogen cylinder and pressure regulator
from the pneumatic actuation line.
xxiv) Re fit coil to the solenoid on the pilot cylinder.
xxv) Re fit the top caps to the iFLOW® valves.
5.5 PILOT CYLINDER SOLENOID TEST
i)
ii)
Remove the pilot cylinder valve top cap (see Figure 43).
Undo the solenoid coil retaining nut and remove the
solenoid from its location on the centre stem of the housing
(if the system has more than one pilot cylinder repeat this
step for every pilot cylinder). See Figure 44.
iii)
Simulate a fire condition at the Extinguishing Control
Panel to energise the solenoid coil.
iv)
While the solenoid coil is energised insert the end of a small
screwdriver into the centre of the coil (see Figure 45). Correct
operation is confirmed by a magnetic field generating a
force which retains the screw driver within the coil. Time
the duration of the activation of the solenoid coil to ensure
that it remains energised for a minimum of three minutes.
Please note that the solenoid coil will gradually heat up
during this activation period.
v)
Reset the Extinguishing Control Panel and check with a
screwdriver that no residual magnetism is present.
vi)
Slowly replace the solenoid coil onto its stem. If the pilot
cylinder valve starts to leak through the pilot port in the
top of the valve immediately remove the solenoid coil. If
leakage occurs check that the Extinguishing Release Panel
is correctly reset. If the panel is found to be reset and the
problem persists contact the OEM’s Technical Department
for assistance.
vii) Once the solenoid coil is in position on its stem fit the
holding nut and tighten with a suitable spanner.
viii) Finally re-fit the top cap onto the pilot cylinder valve.
