Extinguishing aerosol

We develop autonomous stable fire extinguishing devices on the base of the extinguishing aerosol. Our extinguishing agent is made of an ecological mixture with low level of sedimentation and perfect statistical efficiency amongst volume extinguishing measures. After release, aerosol of light weight floats in the air for the tens of minutes as it actively inhibits the fire.

Source of extinguishing mixture

Exactly balanced ratios of inorganic salts impregnated with the formaldehyde resin form an ecological source mixture, which when heated by generator, by impact of small amount of inertial gasses, forms an aerosol extinguishing measure. Gasses deliver ultra-fine powder from the generator and create extinguishing aerosol. Due to the low weight, the aerosol floats in closed space for tens of minutes. After the fire, it is enough to simply remove the settled powder along with the remains of the fire.

Aerosol extinguisher has high efficiency, excellent resistance to external influences and is environmentally friendly. Aerosol FJ does not release any poisons, vapors or fumes into the air. In addition, there is no problem in draining excess oxygen, as with other extinguishing measures.

The success of firefighting depends mainly on the early detection of a fire. We therefore pay close attention to the preparation and deployment of appropriate fire detection systems.

Generators with fire extinguishing mixture and automatic controllers of fire detection with backup power source form a complete system of autonomous fire extinguishing device based on Fire Jack aerosol. If necessary, it is also possible to install a Fire Jack autonomous fire extinguishing device without detection systems and therefore without a power source.

Without the need for a special stock of extinguishing agent or piping system and without a power source, we can provide you with a complete autonomous system and a highly effective extinguishing means, that can completely extinguish the fire.

FJ generators

We are currently supplying a comprehensive range of generators. They are non-pressurized galvanized aluminum containers protected by three-layer coating. For the installation of generators into aggressive environments, we deliver variants made of stainless steel sheet metal. The containers are not under pressure.

Systems of fire detection

To detect fire, automatic fire extinguishing device Fire Jack uses binary signals from the central detection device. To eliminate risks of activation from false signals, in ideal situation we install more than one type of detector into the protected area. Detectors with different principle of work ensure that central detection device signalizes the status of each detector separately and securely identifies the fire.

BEFIS® Automatic

Both the hardware and software of BEFIS® automatic controller is developed by BESY CO spol. s r.o. in the VUMS Control Systems, a.s. embodiment. All technology is designed with an emphasis on high resistance to external sources of electromagnetic interference and simple operation system that prevents malfunctions.

Automatic controller BEFIS®

The standard automatic controller consists of the motherboard of types of ZAH and ZAR, with BAK control blocks, ESA triggers, backup power source and signaling panels. The main control panel (usually in a permanently operated location) communicates with all connected control blocks and continuously checks the status of the entire system. The control panel can also be switched to other modes.

We install control blocks in each room with fire protection, based on the number of triggers. Control blocks consist of microcomputer boards, electronic components and connector for connection to the base plate. The technical solution is readymade for easy and quick repair by simple replacement of boards.

One control block controls up to sixteen connected electronical triggers in the room. When needed, blocks can be organized into groups or operators.

The electronic trigger for activation of extinguishing generators is an addressable device with a power source that triggers the electrochemical starters of the generators. Part of the trigger is a temperature detector with the ability to continuously control data on a connected PC.

Starters

For each type of spaces, we provide generators with a suitable type of a starter. Starters produce initiation heat, which activates the generators of extinguishing aerosol. Types of spaces:

• Electrochemical starter – the starting charge is the charge from the activator of the BEFIS® controller – in case of an automatic version of AED
• Thermochemical starter – activated by external heat source (fire flame, also used in the autonomous version of AED FJ)
• Friction starter –  a type that is manually activated and is intended for portable types of BR generators

Detection devices

To detect fire, automatic fire extinguishing device Fire Jack uses binary signals from the central detection device. To eliminate risks of activation from false signals, in ideal situation we advise installation of more than one type of detector into the protected area. Detectors with different principle of work ensure that central detection device signalizes the status of each detector separately and securely identifies the fire. In most cases AED Fire Jack is completed with its own detection system.
