DESCRIPTION OF SYSTEM
Commercial name: BlazeCut
Characteristics: automatic fire suppression system
Type: Indirect Low Pressure (ILP)
Functionality: BlazeCut system is designed to protect closed spaces, from fire using volume fire suppression, e.g.:
-Engine compartments of mobile equipment and vehicles
-Electrical switchboards, fuse boxes, electrical supply sources, battery spaces,
-Network installations, voltage junctions,
-Server racks,
-Fume cabinets,
-Telecom tower shelters,
-Elevator engine rooms,
-CNC machines,
-AC devices, ventilation devices,

-Spray boxes for paint application,
-Mini power plants,
-Archives,
-Gas boilers, gas regulation stations,
-Windturbines,
-Other.
The fire suppression system operates by detecting fire using a pneumatic BlazeTube detection connected to the
cylinder valve. The BlazeTube detection is placed in the protected enclosure and is under constant pressure
whereby keeping the valve piston closed. In case of fire the BlazeTube detection degrades by the effect of fire or
high temperature. When the BlazeTube detection is disrupted, the pressure in it decreases (LOP system - Loss of
Pressure system) and the valve piston of the cylinder is open. The fire suppression system activates and the entire
extinguishing agent is released. The detection system is independent of any electrical supply and operates solely
on physical principles.
Alternatively the system can detect the fire using electronic devices like Linear Heat Detector (LHD) BlazeWire,
smoke/heat detectors or other. These electronic devices must be used in connection with the integrated solenoid
valve (valve type 10) or end of line solenoid valve in connection with the BlazeTube detection (valve type 35).
BlazeCut systems CEA(FA,NO)10 have integrated solenoid valve (valve type 10), which allows activation of the
system by receiving signal from external device (alarm panel, fire panel, detector etc.).
BlazeCut systems BlazeCut CEA(FA,NO)35 have the valve without integrated solenoid (valve type 35) but the
solenoid can be connected to end of BlazeTube detection as end of line device CSV001.
The system is referred to as indirect, which means that it is activated by BlazeTube detection or electronic
detection and the agent is distributed via separate discharge line with distribution hoses/tubes, fittings and
nozzles.
OPTIONAL COMPONENTS
Installation, use, function and service of selected optional components is described in annexes of the Installation
and service manual or supplied as a separate manual. For more information contact the supplier.
List of BlazeCut optional components for ILP systems
Pressure Switch APS001 –simple mechanical switch with one switch point (fire alarm).
Pressure Transducer ATA100 –constant pressure monitoring with low/over pressure identification and output
for communication.
Alarm Panel AAP200/CAP200 –IP65 small and simple alarm panel in robust aluminum body with LOP/LHD,
manual fire button (AAP200 version), fault identification, universal in dash or external bracket installation.
Signaling Unit ASU001 - simple and cost-effective sound and light signaling unit.
Sounder ASR001 –multi tone red sounder, high base, IP65 rated.
Beacon ABR001 –red xenon beacon, high base, IP65 rated.
Signaling Unit ASU002 –red sounder and beacon, high base, IP44 rated.
Signaling Unit ASU003 –red sounder and beacon, high base, IP65 rated
Solenoid Valve CSV001 - The solenoid valve operates on the principle of automatic release of pressure from the
BlazeTube detection after receiving signal from alarm panel, detector etc. This results in opening of the piston of
the valve of the cylinder, activating the suppression system and completely releasing the extinguishing agent.
This is the same process as during disruption of the BlazeTube detection by effect of fire or heat.
CSV001 is used only in connection with valve type 35 and serves as an end of line device of the BlazeTube
detection. Any instruction in this manual regarding the ending of the BlazeTube detection apply to solenoid valve.
Remote actuator - The remote actuator manually releases the pressure from the BlazeTube detection, which
results in opening the piston of the valve of the cylinder, activating the suppression system and completely

releasing the extinguishing agent. This is the same process as during disruption of the BlazeTube detection by
effect of fire or heat.
CRA203 type: for bulkead mount
CRA204: on wall mount with additional M10x1 outlet.
It also serves as an end of line device of the BlazeTube detection. Any instruction in this manual regarding the
ending of the BlazeTube detection apply to manual actuator.
LHD BlazeWire - LHD BlazeWire works only in connection with the Alarm Panel AAP200/CAP200 or fire panels
and can be supplied with various activation temperatures depending on type of application.
Relay based smoke and heat detectors: ASD001 (smoke detector), AHD002 (heat and smoke detector), AHD001
(heat detector differential).
Remote electric actuators –CRA104 (yellow), CRA105 (blue), CRA106 (red).
INSTALLATION OF THE SYSTEM WITHOUT THE BLAZETUBE DETECTION (ONLY SYSTEMS
CEA(FA,NO)10
Some applications require installation without the BlazeTube detection. In these cases the activation of the
system has to be secured by different method e.g. manually by using electric signal from alarm panel,
automatically by using the LHD BlazeWire, detectors etc. Due to these reasons it is possible to install the system
without the BlazeTube detection only with the valve type 10 with integrated solenoid, systems CEA(FA,NO)10.
In this case the outlet of the BlazeTube detection and the ball valve of the valve of the cylinder is dismounted
and opening on the valve is sealed by a sealing screw or the BlazeTube detection outlet is replaced with additional
M10x1 adaptor.
Never dismount a sealing screw closing the opening of the outlet of the BlazeTube detection. Its
removal would cause immediate opening of the piston of the cylinder and release of the extinguishing
agent.
If the BlazeTube detection is not installed, procedures to the BlazeTube detection and outlet of the BlazeTube
detection mentioned in this manual are not applicable.
Without the BlazeTube detection it is not possible to install the system by using optional components: Remote
actuator CRA203 and CRA204 and Solenoid valve CSV001 as these components require the BlazeTube detection
for operation.
INSTALLATION OF THE SYSTEM WITH THE BLAZETUBE DETECTION OUTSIDE THE PROTECTED
ENCLOSURE
In some cases use of the BlazeTube detection for fire detection is not suitable but can be useful to activate the
system for example manually by using remote actuator or end of line solenoid valve (through alarm panel or
detector).
In this case the BlazeTube detection is not installed in the protected enclosure and is not used for fire detection.
It is only conducted from the valve to remote actuator CRA203 or CRA204 or solenoid valve CSV001 to place of
operation of the system.
In harsh environment or high vibration installations the outlet of the BlazeTube detection on the valve, remote
actuator and end of line solenoid valve can be factory adjusted to fit the LOP hose of same construction and
material as feed hose or distribution hose. LOP hose has higher durability against mechanical damage compare
to BlazeTube detection.
All instructions in regards to the BlazeTube detection, its installation and pressurization in this manual remain in
reasonable force.

2.2. USE OF THE SYSTEM
BlazeCut system is designed for protection of closed spaces from fire using volume or local fire suppression.
The fire suppressing properties depend on many factors, including the size of the protected enclosure, the
properties of the flammable substances in the space, shape and degree of closure of the area, the possibility of
placement of extinguishing nozzles, air circulation etc. In order to reach desired extinguishing concentration and
effective use of BlazeCut system consult the choice of type, amount of agent and cylinders, type of extinguishing
agent and installation method with the supplier of the system.
In order to achieve accurate design of the system it is necessary to be priorly informed of at least the following
parameters:
The dimensions of the protected area,
Openness of the protected area and airflow in it,
The nature of fire risk in the protected area (presence of flammable materials, their amount, location),
Layout of the protected enclosure,
Sites with the highest probability of fire (presence of possible ignition sources of fire),
Placement options of the system within the protected area (especially the location of the cylinder,
distribution tubes/hoses, nozzles, and BlazeTube),
The presence of people in the protected area, method of operation of the protected equipment, etc.
It is always recommended to discuss the potential fire risk factors and factors in the protected enclosure with a
local fire protection specialist who has knowledge about the protected enclosure and these information are
provided to the supplier of the system.

[e-mail] ILP CLEAN AGENT MANUAL-ILPCAM1904
BlazeCut and the BlazeCut logo are the registered trademarks of BlazeCut © 2019 BlazeCut, All rights reserved
It is also necessary that the conditions in the protected area are in accordance with the permissible parameters
of the system, especially the lowest and highest temperature in the protected area.
Remember that there are a lot of factors and variables that affect the extinguishing process in case of fire. Is not
possible to guarantee total suppression of fire in the protected enclosure under all circumstances.
System BlazeCut is designed to protect of equipment in closed spaces. Use in partially or completely open spaces
or spaces with strong air circulation may significantly decrease the efficiency of the system.
In case of forced ventilation in protected enclosure after activation of the system the ventilation shall be
switched-off immediately to avoid venting of the agent from the protected area. In such case it is recommended
to provide automatic cut-off of the ventilation when system BlazeCut is activated (e.g. with the Pressure Switch
APS001).
Use of the system is also limited by the properties of extinguishing agent and its possible application. Detailed
information are described in Chapters to each extinguishing agent.
BlazeCut system was designed and tested as a whole using original components with specific properties. Using
other than components supplied by the manufacturer and spare parts is prohibited and may change the
functionality of the system and causes loss of warranty. To order original spare parts and for further information
contact the supplier of the BlazeCut system.
WARNINGS
Install and use system BlazeCut only with originally supplied components. Do not replace anything in
the system, use only original components and spare parts. Use of components not approved by the
manufacturer causes loss of warranty, may cause malfunction of the system and provides threat to
safety and health of people.
System BlazeCut is designed as independently operating unit (also in case of multiple cylinder
connection). It is not possible to connect several independent systems into one unit.
System BlazeCut is not compatible with other fire suppression systems, do not try to connect the
system to any other equipment.
The system may be installed, maintained and repaired only by persons trained or authorized by the
manufacturer and also holding relevant professional qualification depending on the procedure.
Unprofessional interference with the system may cause malfunction of the system and provides
threat to safety and health of people.
The system is not designed to be used as portable fire extinguisher. Do not try to suppress fire by
holding the system in hands or sprinkling the extinguishing agent directly into the fire. Do not use the
system in any other way than described in this manual.
3. COMPONENTS OF THE SYSTEM AND THEIR DESCRIPTION
