3.0 Design of the AF-X Fireblocker Carbon Series
General description:
1) The AF-X Fireblocker Carbon Series generator has a steel casing and comes in various shapes and sizes see
annex 1.
2) The AF-X Fireblocker Carbon Series generators contain a solid, aerosol-forming compound (“SAFCO”).
3) Each container is equipped with a special system for independent activation of the generator.
4) All types are equipped with a heat absorbing mechanism (insulation).
A tension of 12/24 V (Direct Current) on the AF-X Fireblocker Carbon Series generator and an electric current of at
least 0,02 amperes for 1,0 seconds activates the extinguishing agent and convert it into dispersed micro and nano
particles. The aerosol is then cooled by the heat absorbing elements and discharged into the protected area, blocking
the fire by stopping the combustion chain reaction. Activation simultaneously triggers other chemical reactions
ensuring a final product that is harmless to man, matter and the environment.
All generators of the Carbon Series are equipped with:
• An integrated AF-X connector for swift and flawless installation
• An activator for electronic activation
• A transportation bracket to neutralize outflow pressure

When working with the AF-X Fireblocker Carbon Series it is prohibited to:
- open and/or dismantle extinguishing units;
- by any means apply force to the units that could result in distortion, physical or mechanical
damage to the casing;
- carry out welding activities in the vicinity of the AF-X Fireblocker extinguishing units;
- smoke in the vicinity of the AF-X Fireblocker extinguishing units.
In case an extinguishing unit has fallen, it should be checked for damage to the activator’s electric
switch and/or other components. When damage and/or dysfunction cannot be ruled out with
certainty, the unit cannot be used and must be returned to the authorised AF-X distributor or
dealer.
Please see to it that all legal requirements, regulations and advice are adhered to. Pay attention to the
risks involved in working at height. Be careful of your footing and use reliable tools and proper personal
protective equipment. Should you have any queries, please consult your employer and/or qualified
consultancy agencies.
To avoid unnecessary exposure of occupants to the discharged extinguishant, factors such as the time
for egress and the risk to the occupants by the fire should be considered when determining the system
discharge time delay. Where national standards require other precautions, these should be
implemented
5.0 Design and installation of the fire extinguishing system
A standalone AF-X Fireblocker Carbon Series generator can be activated by means of a thermal circuit (e.g. an AF-
X bimetal switch that activates at 65 ºC, see annex 2).
The self-activation temperature of the compound is 350 ºC. The self-activation time of the electronically controlled
activation device is > 170 ºC. Please note that equipment used for heating or welding, and other sources of energy,
might provoke activation of the fire extinguishing generator if the self-activation temperature is reached.
The standard requirements for an aerosol fire extinguishing system with extinguishing generators are:
1. The Fire Extinguishing Control Panel FECP (whether or not connected to a Fire Alarm System, FAS) which
connects, supplies power to, monitors and controls the various components of the extinguishing system.
2. Detection equipment feeding the FECP with information on possible fire hazards.
3. Alarm system giving acoustic or optical signals to warn or inform people present in the protected area about
the current situation.
4. AF-X Fireblocker Carbon Series extinguishing units (generators) that, when activated by the FECP, discharge
the fire blocking aerosol into the protected area.
5. Wiring and connectors connecting the various parts of the system. Often included in this group are alarm
enabling and disabling switches for manual intervention in the FECP controlled process.
5.1 The Fire extinguishing control panel (FECP)
There are many fire extinguishing systems on the market. When selecting your FECP it is important to consider the
local rules and regulation concerning fire extinguishing systems in general and aerosol fire extinguishing systems in
particular.
The extinguishing generators and other equipment must be fed with the required activation voltage and current.
Note that the extinguishing generators are activated by a heating element with 6,8 (±10%) Ohm resistance. The
required electric activation voltage is 12/24 Volt DC with 1,2 Ampère for not less than 1 seconds. A control or test
current of no more than 0,02 Ampère can be applied without activating the generator.

(European) Extinguishing systems with the AF-X Fireblocker Carbon Series can be designed using one of the
following control panels:
1. Kentec Sigma XT or A-XT panel
2. Honeywell Notifier RP1r-SURPA
3. Siemens Cerberus, for systems with more than 10 extinguishing generators
4. AF-X Marine Panel for shipping
5. DECU2
6. AF-X TEC
All these control panels have their own prices and possibilities. If the usage of other brands or types of control
panels is considered it is required to contact the technical department of AF-X Systems first for an opinion and
approval regarding compatibility. Also, if a certifying authority requires the usage of a specific panel.
For proper installation of the panel of your choice, we expressly refer you to the manufacturer’s installation
requirements.
For installations designed for countries where European Rules & Regulations do not apply, we advise to consult the
technical department of AF-X Systems first for proper advice regarding this matter.
5.2 AF-X MCU (monitoring & control unit)
The AF-X MCU provides connection from the Kentec XT, AX-T or the Honeywell Notifier RP1r-SURPA fire control
panel to the AF-X Fireblocker Carbon Series generators.

5.3 Detection systems and peripheral equipment
The fire extinguishing system’s Statement of Requirements determines which detection system and/or peripheral
equipment will be chosen. For European extinguishing systems, AF-X Systems uses equipment such as (optical)
alarms, temperature-sensitive equipment or aspiration systems for detection. In addition, systems and switches
might be used enabling manual intervention in the FECP-controlled process.
The AF-X Systems price list includes most of such products enabling the system designer to use standardized and
compatible products.
Please be aware that local rules and regulations, or a certifying authority, may require specific equipment. For
proper installation of the systems, the manufacturers’ installation requirements are leading.
5.4 AF-X Fireblocker Carbon Series extinguishing generators
For the correct design of an AF-X Fireblocker system, the following steps must be taken:
1. Calculation of the required quantity and type of extinguishing generators.
2. Projection of the generators’ correct position in the (to be) protected space.
3. Determination of the extinguishing generators’ correct discharge direction.
5.5 AF-X Fireblocker Carbon Series aerosol behaviour
For a correct design of an AF-X Fireblocker extinguishing system with the Carbon Series, one should consider several
properties and behavioural aspects of the AF-X Fireblocker aerosol of the Carbon Series in the protected space.
The aerosol formed by the AF-X Fireblocker leaves the generator at some speed. You will observe a spreading,
homogeneous cloud. The temperature of this cloud, consisting of extremely small microscopic particles, is usually
higher than its surroundings. Therefore, the aerosol cloud will initially seem to be slowly rising.
The particles are so small that gravity hardly affects them, and they can therefore disperse in the air rapidly and in
a balanced fashion. This also means that the currents and whirls present in the area (either caused by fire, or just
by the active equipment) make the tiny aerosol particles actively move through the protected space. The AF-X
Fireblocker aerosol of the Carbon Series has been designed to make use of these currents and movements so that
the convection currents, caused by the seat of the fire, draw the particles into that seat. Even when the fire is just
in its early stages of development.
5.6 Calculation of quantity and type
The calculation of the necessary quantity and type of extinguishing generators is simple and in principle all you need
is the net volume (in m3) of the space you want to protect. The net volume is usually specified on the Program of
Demand of the project, or at Technical Drawings of the construction. Should you lack this information, you will find
more information in the “Manual Volume Calculation” that is available on request. If the net volume of the to be
protected space is provided to the system designer by a third party, it is strongly advised to check this number
based on factual information.
When you have the available net volume of the to be protected space at hand you can use the “AF-X Fireblocker
Density Calculation Sheet” to determine the amount of extinguishant you need, and which types of extinguishing
generators will best suit your purpose. This Calculation Sheet is available upon request with AF-X Systems at all
times.
For each generator type, the volume the generator protects is stated by fire class. In line with most European and
American guidelines, one should add an (extra) safety margin of 30% in the calculation (this margin is included in
the numbers in the Calculation Sheet).
5.7 Projection of the generators within the area
There is a number of guidelines that help you determine the best positions for the generators in your design. These
guidelines are based on standards, but each area is different. It is important to adhere to the standards as much as
possible. Needless to say, the distribution of generators in the area needs to be in accordance with local rules and
regulations as well as the system’s Statement of Requirements.
5.8 Guidelines for the correct positioning and distribution in the area
1. Generators need to be positioned and distributed in such a way that the discharged aerosol can be dispersed
in the protected area’s free space as quickly and homogenously as possible.

publication of a revised issue. The latest version is available with your
distributor, dealer or at AF-X Systems BV.
User Manual AF-X Fireblocker Carbon Based Fire Extinguishers version 2.2

2. Generators are preferably mounted on the wall or at the ceiling, with the discharge opening pointing
downwards at an angle from the ceiling or wall respectively (cf. ‘discharge direction’ below). The higher
and or bigger the enclosed space, the more vertically downwards the generator should be directed. If a
space is protected by one generator only, it might be best to mount the generator pointing downwards in
the centre of the ceiling.
3. The units need to be evenly distributed in the area.
One larger generator could be more cost effective than two smaller, the use of two generators could be
more effective than using four, but there are no absolutes. The deciding factor on the number of generators
in the design should be based on whether the chosen number could fill the area with aerosol rapidly and
evenly. After all, every nook and cranny need to be filled with sufficient aerosol. When in doubt, do not
hesitate to contact the AF-X Systems experts.
5.9 Determination of the correct discharge direction
There are always several solutions. The challenge is to come up with the optimal mix of choices in type, position
and discharge direction and length that makes maximum use of AF-X Fireblocker’s qualities and is in accordance
with the Statement of Requirements as well as the local rules and regulations.
4. Preferably, generators are mounted to the wall just under the ceiling with the discharge opening directed
downwards.
If a free downward outflow is not possible, the generators can be mounted on the ceiling, also with the
discharge opening directed downwards.
5. Generators need to be positioned in such a way that all discharged aerosol is dispersed unhampered and
in full in the area to be protected. This also implies that the generators always need to be projected
towards unobstructed space, away from windows, doors, grates, vents, lids, valves, man-holes, transom
windows or other openings. This includes openings that are usually closed or pushed closed with door-
closers or automatically by the FECP before extinguishing starts.

Away from windows or other potential openings:
6. In an area with a height of less than 1m, generators should preferably discharge horizontally.
Horizontal discharge in areas lower than 1m:
7. In an area higher than 1m, generators should preferably discharge downwards at an angle (cf. drawing).
Downward discharge in areas higher than 1m:

8. In areas higher than 2m, generators should be placed in the meter of space directly below the ceiling.
For high area’s (e.g. higher than 8m), it may be advisable to work with two ‘installation rings’. Please
consult the AF-X Systems experts when designing systems for areas of such height.
High areas, placed within one meter below ceiling:
9. It is of the utmost importance that there are no obstacles in front of the discharge opening for a distance
of at least the length of the AF-X generator itself.
Avoid obstacles in front of discharge opening:
5.10 Mounting guidelines AF-X Fireblocker Carbon generators
Please note that the AF-X Fireblocker generators should be mounted in static environments.
a) Please study the entire systems’ projection plan carefully before mounting any generator.
b) Systems with a fire extinguishing control panel should at all times contain a maintenance switch separating
the extinguishing units from the control panel during installation as well future maintenance activities.
c) For the installation of cables use the cables sold and/or advised by AF-X Systems only and make sure that
they are installed neatly, systematically and securely. Follow the cable manufacturer’s guidelines regarding
the installation of cables closely.
d) De AF-X Fireblocker generators are standard equipped with an IP55 connector chassis with a female inlay
(cf. product drawing). Using the proper tools, the installer must equip the control cable with a cable gland,
a hood and a male inlay, that AF-X Systems supplies.
e) The male insert is properly connected to the (massive core) control cable with a stripping length of 15mm
to pole number 1 and pole number 2, using a maximum torque of 0,5 Nm. The AF-X Fireblocker is not
earthed.

f) De AF-X Fireblocker generators must be mounted in isolation (even if the Statement of Requirement does
not specify as such). Attach the mounting brackets, which need to comply with local rules and regulations,
to the wall, ceiling or other location, using the insulation glands and rings in all mounting holes that connect
the bracket to the mounting surface. Do this in such a way that the extinguishing units cannot move or get
damaged inadvertently.
g) Take the AF-X Fireblocker from its packaging. Check the product for visible faults or damage as a result
of transport, etc. Take the AF-X Fireblocker from its packaging. Check the product for visible faults or
damage as a result of transport. Some generators are packed with nozzle protection brackets and
stickers. Remove them carefully and completely to assure the free outflow of aerosol during activation.
h) The AF-X Fireblocker is delivered with a short circuit safety between the poles 1 and 2 of the female inlay
in the connector. This prevents unwanted currents in the activation unit. To assure a secure and safe
installation of the generator, please keep the short circuit safety as long as possible in its safeguarding
position.
i) The cylindrical AF-X Fireblockers (Type CS and CM) are delivered with a protection cover on the nozzle.
After unpacking remove the protection cover.
j) Check whether the electric circuit of the AF-X Fireblocker generators is intact with an ohmmeter with an
accuracy of at least 2.5%. The resistance must be between 6.1 and 7.5 Ohm.
The test current should not exceed 20 mA for a maximum of 300 seconds.
k) Attach the AF-X Fireblocker firmly to the mounting brackets with the clasp and ensure an unobstructed
discharge. It is very important that there be no obstacle in the space immediately in front of the discharge
for a distance of at least the length of the AF-X Fireblocker generator itself (cf. drawing above). Always
maintain distance to cable ducts. Although the AF-X aerosol’s discharge temperature should not be
damaging to the cables, it is important that the discharge cannot be influenced. The correct distance at
which this unit must be installed is to be found on page 20 in annex 1.
l) The MCU Monitoring and Control unit is specially developed for application at Kentec Sigma XT, AX-T or
the Honeywell Notifier RP1r-SURPA panels. The connection will be displayed in the image on page 9.
m) Before attaching the AF-X Fireblocker connector, check whether the cables have been connected to the
disabled maintenance switch correctly (red LED on the maintenance switch is on), and whether the
maintenance switch has been connected to the Fire extinguishing control panel correctly.
n) Connect the power supply to the appropriate parts of the fire extinguishing system.
o) Check whether the Fire extinguishing control panel functions properly.
p) Check whether all requirements in this manual have been met.
q) The final step is to switch the maintenance switch(es) to ‘on/active’ (red LED is off)

8.0 Maintenance of the AF-X Fireblocker
For the duration of its use the AF-X Fireblocker must be subjected to the following inspections and maintenance,
performed by qualified, i.e. in accordance with local laws and norms, technical staff:
• Check the extinguishing unit for any damage
• Check whether the sticker on the discharge opening is still secure
• Check the log
• Measure the resistance
• Check whether the projection is in accordance with delivery
• Check the mounting brackets and attachment
• Check whether the label on the extinguishing unit is securely fastened
• Check the unit’s life span, see expiry date on the label of the AF-X Fireblocker
NB the entire system, including all parts, must be checked regularly in accordance with the suppliers’ guidelines
and/or local laws.
The AF-X Fireblocker Carbon series have been designed for a service life of 15 years. Please be aware that
the extinguishant contains materials that have a relatively low melting temperature. These materials increase
the extinguishant’s efficiency, but it is therefore important to always ensure that the AF-X Fireblocker is not exposed
to temperatures that are outside the normal operating temperature range of -20 and + 50 degrees Celsius, as
stipulated in this manual. The service life of the AF-X Fireblocker is monitored by the producer by testing product
batches on a regular basis.
9.0 Residue removal, disassembly, waste and the environment
9.1 Introduction
Upon activation, the SAFCO converts into rapidly dispersing aerosols, consisting of solid micro particles suspended
in gas.
The concentration of solid particles suspended in the aerosol phase is a few milligrams per m³. The particles are
water and moisture-free and, after passing the hold-time, settle as dust in the protected area. The dust should be
removed before it absorbs moisture.
Thorough cleaning by removing all aerosol particles prevents the aerosol and combustion residue suspended in the
air from absorbing moisture so the particles cannot react any longer to electronic parts, metals, etc.
Should the aerosol particles remain on the surfaces for an extended period of time, they might absorb moisture,
thus risking a reaction of the moisture to metals (particularly uncoated metals), possibly resulting in oxidation.
After activation it is recommended to have delicate metals and equipment cleaned by a specialised company.
9.2 Residue removal
See and follow chapter 7 of the SDS that is added as Annex 3 to this manual for necessary personal protection
before entering the room.
- Although the aerosol in itself is harmless, ventilate the area for at least 30 minutes after activation. Do not
enter the area until after it is sufficiently ventilated.
- To avoid any unwanted side effects, remove the residue (within a couple of hours).
- Vacuum the dry residue from the floor and metals using a vacuum cleaner.
- Dust the residue from electric parts using a fan or ventilator.
- Use special sprays or dry ice cleaning suitable to remove residue from electronic parts.
NB although the residue is harmless to man and the environment, it is recommended to wear a dust
mask during cleaning activities because of particulates.
Always contact your distributor or dealer after AF-X Fireblocker activation; they will assist you in
renewed projection as well as the correct reconditioning and cleaning methods of the area
concerned
