User Manual AF-X Fireblocker Nano Series version 3.5

1.0 Introduction

AF-X Fireblocker is designed to extinguish surface burning fires Class A&B. This manual is written in such a way that

it covers most of the important aspects of the AF-X Fireblocker’s functional use. Therefore, to ensure functional use

of the AF-X Fireblocker, all instructions of this manual need to be followed closely.

Electrical installations, such as fire detection, control and alarm systems, need to be designed, installed and

maintained by the systems supplier trained (certified) personnel according to this manual and instructions. Local or

National standards, guidelines or other legislation regarding these matters are not included in this user manual.

The aerosol generated, may create a potential hazard for personnel and equipment in the protected area. While

generating aerosol, there are high temperature products of the extinguishing media discharged and this

characteristic should be evaluated before the generators are installed.

In case of incorrect use of the information in this manual AF-X Systems BV will not accept any responsibility for any

damage caused by the AF-X Fireblocker system.

2.0 Scope

AF-X Fireblocker is based on a condensed aerosol and designed to be part of a total flooding fire extinguishing

system. Precondition for powerful performance is the unit’s connection to and activation by an effective fire detection

system. Rapid detection and reaction are vital.

AF-X Fireblocker can be used in spaces that are normally unoccupied. Cylindrical generators can additionally be

placed in motor compartments or otherwise vibrating environments.

AF-X Fireblocker and other aerosol extinguishants have been recognized as effective media for the extinction of

Class A fires (solid surface burning fires) and Class B fires according to EN 2 but it should not be forgotten, in the

planning of comprehensive schemes, that there can be hazards for which these mediums are not suitable, or that

in certain circumstances or situations there can be dangers in their use requiring special precautions.

AF-X Fireblocker cannot be used with:

• Materials with non-surface burning fire potential, or possible chain reaction of the organic fuel, oxygen and

temperature within the material(s), bulk smouldering fire potential, e.g. in cocoa beans, rubber;

• Oxygenic chemical compounds such as nitrocellulose and gunpowder;

• Reactive metals such as lithium, sodium, potassium, magnesium, titanium, zirconium, uranium and

plutonium;

• Metal oxides;

• Organic peroxides and hydrazine

User Manual AF-X Fireblocker Nano Series version 3.5

3.0 Design of the AF-X Fireblocker

General description of the AF-X Fireblocker:

1) The AF-X Fireblocker has a stainless-steel casing and comes in various shapes and sizes see annex 1.

2) The AF-X Fireblocker contains a solid, aerosol-forming compound (“SAFCO”).

3) Each container is equipped with a special system for independent activation of the AF-X Fireblocker.

4) All types are equipped with a heat absorbing mechanism (insulation).

A tension of 6-36 V (Direct Current) on the AF-X Fireblocker and an electric current of at least 1,0 amperes for 1-2

seconds activates the extinguishing agent and convert it into dispersed 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.

Schematic illustration of the AF-X Fireblocker with its 6 key components:

1. Connector to ensure quick installation

2. Patented extinguishing agent to ensure rapid and effective fire extinguishing

3. Activator

4. Balanced space to ensure optimum action and interaction.

5. Thermodynamic cooling to ensure a controlled efflux temperature

6. Aerodynamic discharge opening to ensure a quick and optimum dispersal in the protected area

and trained persons and in accordance with the latest applicable local laws, regulations and

standards.

When working with the AF-X Fireblocker it is prohibitedto:

- 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 a standalone system with one generator

A standalone AF-X Fireblocker generator can be activated by means of a thermal circuit. For this the AF-X Bimetal

Switch can be used. A standalone system cannot be larger than the max coverage volume of the generator.

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 of 300 ºC will be reached.

5.1 Design and installation of a multiple generator system

The fire extinguishing system’s basic design determines which detection system and/or peripheral equipment will

be chosen. Please be aware that local rules and regulations or a certifying authority may require specific

equipment. For proper installation of the systems we expressly refer to the information in this DIOM and to the

Fire detection and fire alarm systems manufacturers installation requirements.

The minimum standard requirements for an aerosol fire extinguishing system with multiple 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 must

comply to CEN/TS 54-14, Fire detection and fire alarm systems - Part 14: Guidelines for planning, design,

installation, commissioning, use and maintenance or to similar local legislation, guidelines and / or standards;

2. The Fire Extinguishing Control Panel FECP must be able to provide sufficient energy to activate all the

generators in the system and as designed;

3. Unless otherwise specified in a standard, 72 h minimum standby sources of energy shall be used to provide

for operation of the detection, signalling, control and actuation requirements of the system.

4. Fire detection and fire alarm system must be able to generate acoustical and optical signals to warn or inform

people present in the protected area about the current status;

5. Wiring, components and connectors connecting the various parts of the system must meet the relevant part

of EN54 or similar.

Note: Specific conditions and / or special applications shall always be verified by AF-X systems.

There are many fire extinguishing systems on the market. When selecting a FECP it is important to consider the

local rules and regulation concerning fire extinguishing systems in general and aerosol fire extinguishing systems

in particular.

Note that the extinguishing generators are activated by a heating element with 1.3 – 3.2 Ohm resistance.

The required electric activation voltage is 6 -36 Volt DC; 1.0 Ampère (= 1000 mA) for 1-2 seconds.

5.2 AF-X MCU (Monitoring & Control Unit)

The extinguishing generators are activated by a heating element with 1.3 – 3.2 Ohm resistance. The required electric

activation voltage is 6 -36 Volt DC; 1.0 Ampère (= 1000 mA) for 1-2 seconds.

In order to assure that the activation power of the Fire Extinguishing Control Panel FECP is distributed correctly

throughout the multiple generator system, the monitoring and control units were developed.

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 Fireblockers.

• A maximum of 18 AF-X MCU’s can be connected to each extinguishing line,

• A maximum of 2 AF-X Fireblockers on each MCU.

5.4 AF-X Fireblocker design parameters

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 extinguishing generators correct position in the area to be protected;

3. Determination of the extinguishing generators correct discharge direction.

5.5 AF-X Fireblocker Aerosol behaviour

For a correct design of an AF-X Fireblocker extinguishing system, it is important to consider several properties and

behavioural aspects of the AF-X Fireblocker Aerosol in the area to be protected.

The aerosol formed by the AF-X Fireblocker leaves the generator at some speed. This can be observed as a

spreading transparent-white cloud. The temperature of this cloud, consisting of extremely small nanoparticles, is

usually somewhat higher than its surroundings. So, initially the aerosol cloud and the temperature in the

enclosure will therefore seem to be slowly rising.

The particles are so small that gravity hardly affects them, and they can disperse in the air rapidly in a balanced

fashion. The currents and whirls present in the area, either caused by fire or just by the active equipment, make

that the tiny aerosol particles actively move through the area. The AF-X Fireblocker Aerosol has been designed to

make maximum use of these currents. By consequence, the convection currents caused by the seat of the fire

draw the particles into that seat. Even when the fire is just in its very early stages of development.

Design density calculation

Manual calculation of the design density can be done using the following formula used in EN15276-2 and NFPA

2010:2015

The effective mass of aerosol in the system shall be at least sufficient for the largest single hazard or group of

hazards that are to be protected against simultaneously.

The mass of extinguishant required to achieve the design application density shall be calculated from Formula:

M = ρ×V

where

mis the total flooding quantity, in g;

ρis design application density, in g/m3 (may need to be adjusted to compensate for any special conditions that

would adversely affect the extinguishing efficiency, consult AF-X Systems);

Vis protected volume, in m3 (may include adjacent connected hazards or work areas).

The design density is the extinguishing density multiplied by the mandatory safety factor of 1.3

In addition to these calculated total flooding quantities, additional quantities of extinguishant can be required by

standards to compensate for any special conditions that would adversely affect the extinguishing efficiency or, if

required, by the physical characteristics of the extinguishant. Consult AF-X Systems in case of special environmental

conditions or applications.

AF-X Fireblocker generator size and quantity selection

In case of the need of more than one aerosol generator to protect a volume, preferably generators of the same

family should be used. In all cases the design shall be realized according to the determined coverage tests of the

AF-X Fireblocker generator(s) involved.

NOTE: As each condensed aerosol generator contains a distinct amount of the solid aerosol-forming compound,

there can be a few options in regard to the unit size and number of the aerosol generators that would be

adequate to achieve the required design quantity.
