The comprehensive task performance may also comprise design and provision of fixed fire-fighting systems.

ventilation and smoke removal systems

What we will do for you

Our supply may comprise design and implementation of a ventilation and smoke removal system or a complete fire-fighting system. Apart from the ventilation and smoke removal system, the complete solution may comprise fixed fire-fighting systems, voice alarm systems, emergency and escape route lighting, as well as flammable gases detection systems.

At the existing structures we integrate our solutions with the safety systems already present in place, which guarantees their efficient operation as one whole. Additionally, the design work may be preceded by preparing a fire safety plan and fire scenarios.


The current regulations require that a fire safety plan and fire scenarios for the premises subject to fire hazard are prepared. They are basis for further works consisting in designing and implementing the fire alarm systems or complete fire-fighting systems. If no such documents have been prepared for the respective structures, we may start from preparing them..

  • Fire safety plan – the document is required for buildings and their parts representing separate fire zones, intended for performing public utility functions, boarding house, production building, warehouse, livestock building, where hazard explosion zone is present, or:
    • the gross cubic volume of the building or its part representing a separate fire zone exceeds 1,000 m3 (does not apply to livestock buildings),
    • the gross cubic volume of a livestock building exceeds 1,500 m3,
    • the fire zone area of a structure other than a building exceeds 1,000 m2.
  • Fire scenarios – a fire scenario is a description of the sequence of the possible events during a fire, representative for the respective place of its occurrence or area of impact, specifically for a fire zone or a smoke zone, considering mainly the way of operation of fire-fighting equipment, utility or engineering equipment, as well as their joint operation and interaction, and also organisational solutions needed for the proper operation of the designed safety measures..
  • ATEX documents – apart from the aforesaid documents, mainly in reference to industrial structure, our documentation department also prepares such documents as:
    Explosion Hazard Zones Setting
  • Explosion Hazard Assessment
  • Explosion Risk Assessment
  • Explosion Protection Document


We design smoke removal and ventilation systems for enclosed structure, underground storeys, garages, halls as well as escape routes and staircases. We take into account not only the binding regulations and standards but also the characteristic features of the structure, selecting effective and cost-efficient solutions..

The system may by delivered as an independent system with its own control panel and a system of detectors or may be integrated with the existing fire detection system. We also provide designs of complete fire-fighting systems, which cover, among other things, a fire detection and alarm system, smoke removal and ventilation system, emergency and escape route lighting, as well as fixed fire-fighting systems..

Selected components applied in the designed smoke removal and ventilation system:

  • Control panel with the option to control proper operation and power supply
  • Smoke removal system ducts
  • Smoke removal system ducts
  • Fire dampers
  • Fire ventilation dampers
  • Smoke dampers
  • Smoke ventilation windows
  • Manual smoke vent buttons (MOV)


A smoke removal and ventilation system are an important but not the only system protecting human life and the civil engineering structures against damage. It is important that all of the solutions making up a fire safety system operate flawlessly and automatically – the actuation of one system should actuate the others. Only in such situation the fire-fighting system is effective. Therefore, within our works we guarantee integration of the fire alarm system with other safety and building automation systems (see the list below). We also create visualisation, which we combine with the building or industrial system layout plans. This enables implementation of the assumed fire scenarios and managing the whole safety system in an efficient and intuitive manner.

The systems we integrate:

  • smoke removal and ventilation system
  • wire and wireless fire detection and alarm systems
  • access control system
  • voice alarm system
  • fire lockout system
  • fire dampers system
  • lift system
  • explosion protection system (industry)


With our installation group we are capable of performing tasks in a comprehensive manner, i.e. starting from preparing fire scenarios, through concept and design, and ending with delivery and installation of a smoke detection and ventilation system or a comprehensive fire-fighting system. In this way our customer may rely on a partner responsible for all of the implementation stages. Such solution may significantly facilitate the investment process, providing a guarantee that the final effect complies not only with the legal requirements but also the customer’s individual expectations.

Structures for which we prepare smoke removal and ventilation systems

Smoke removal systems are used for the protection of health and life of people staying at various building structures. Their task is not only to ensure fast and safe evacuation but also to enable the rescue service to operate on site during fire. In the stand-by mode, the smoke removal system may also act as a ventilation system providing proper air exchange in the building, thus ensuring comfort to the people staying inside.

The typical structures for which we develop and implement fire-fighting systems but also smoke removal and ventilation systems include large enclosed structures, halls, commercial centres, high-rise buildings, underground garages, buildings with underground storeys as well as staircases.

smoke removal and ventilation systems


Industry requires dedicated smoke removal and ventilation systems which will be resistant to interference from other machines and equipment and also adequate to the working conditions. The applied solutions must be fit for work in high-dustiness environment, variable temperatures and humidity. They must frequently be fit for operation in explosion hazard zones.

At industrial structures there may be present gas or smoke produced in normal operation of systems and equipment, which may result in false alarms generated by a fire detection and alarm system. In order to avoid the problem, if the circumstances so require, we apply sub-assemblies resistant to such interference, which may additionally operate in coincidence mode.

Our experience and technology are important ensure protection of:

  • industrial structures and systems, generally understood
  • structures with hazard explosion zones
  • conveyor belts
  • inclined coal conveyor galleries
  • storage yards
  • silos/bunkers/dispensers
smoke removal and ventilation-systems for office buildings


Office buildings are frequently characterised with large space spread over many storeys connected by way of lifts and staircases. Apart from office rooms or open space floors such buildings may house a number of premises of different nature (restaurant kitchens, server rooms, cold stores, emergency power rooms, conference halls, shops, warehouses etc.). A good designed smoke removal and ventilation system must cover for the specifics and be integrated with the automation and access control systems operating in the building.

smoke removal and ventilation systems for commercial centres


Supermarkets and commercial centres may have several storeys connected by way of lifts and/or staircases. Underground, garages are often located, and within the commercial space, shops and warehouses full of products which may fuel the fire. Other typical spaces for commercial centres are cinemas, gyms, server rooms and kitchens using open fire. Designing a smoke removal and ventilation system is a challenge not only with regard to safety but also ensuring proper air exchange to care for the comfort of the people inside.

smoke removal and ventilation systems for airports


Airline transport has recorded an extremely fast growth within the last 20 years. Today’s airports service several thousand to several million passengers a year. This means that everyday thousands of people are staying inside. Our task is to design and implement a smoke removal and ventilation system or a comprehensive fire-fighting system, such as to ensure the highest safety level.

smoke removal and ventilation systems for hotels


Hotels are special buildings where fire may originate in many different spaces. This may include kitchens using open fire, guest rooms where a short-circuit may occur or fire may be started by guests, reception and concert halls where pyrotechnics are frequently used, as well as saunas and underground garages. All this requires a smoke removal and ventilation system or a complete fire-fighting system adjusted to each of the spaces, in consideration of the working conditions.

smoke removal and ventilation systems for hospitals


Hospitals are complex structures as regards topography and frequently consist of separate buildings located on a large area. Their operation must be stable, and a series of procedures must not be abandoned even in case of fire. On the other hand, the hospitalised persons often suffer of limited movement capacity, which significantly affects the time and method of evacuation. All this means that a smoke removal and ventilation system or a comprehensive fire-fighting system must ensure the highest safety level, which will prevent fire development due to fast reaction and/or will ensure the longest possible time for evacuation.

Selected components of a smoke removal and ventilation system

Below listed are selected components based on which we implement smoke removal and ventilation systems as well as fire detection and alarm systems in civil structures. As may be seen, we use a broad range of solutions fit for a variety of buildings. We are, therefore, capable of developing optimal solutions as regards technology and costs, which fulfil the specific requirements of a given building.


We are experienced in designing and implementing smoke removal and ventilation systems based on components by major Polish and international manufacturers. In that regard, we are be able to advise the best solution which fulfils the investor’s requirements. If a specific solution is preferred, the selection of components suggested by the customer may be applied providing that that does not affect the safety level.


Within our work we integrate smoke removal and ventilation systems with the existing safety and automation systems in a building. Our solutions are compatible with a majority of systems available on the market. An example integration may entail connection of our system to the following systems:

  • fire detection and alarm system
  • building automation system
  • water/foam/gas extinguishing system
  • voice alarm system


As regards smoke removal and ventilation systems intended for industrial plants where explosion hazard zones are present, we use components fit for work in explosion hazard zones (ATEX certificates).

Additionally, we are capable of integrating the fire-fighting system with an explosion protection system, which guarantees streamlined and safe operation of both systems.

Control panel

Fire alarm control panels of various level of complexity. Designed in consideration of the highest safety standards and simplicity at each stage of implementation, starting from assembly, commissioning and daily use. The control panels may be integrated with external systems, e.g. through ESPA 4.4.4, NMEA-0183, MODBUS protocols. The control panels have menus in Polish. The piece of equipment has a self-test mode, which is started automatically every day.

Components of a removal and ventilation system

A smoke removal system consists of dozens of different sub-assemblies which are intended to remove smoke and heat and/or limit smoke spreading. In our systems we use, among other things: fans, smoke vents, smoke ventilation windows, fire dampers, smoke dampers, intake and exhaust vents, ducts and mounting fittings.

Smoke detector

It is a standard addressable detector applied in a majority of fire alarm systems. The detector may be adjusted with regard to sensitivity, while the embedded temperature-sensitive resistor enables temperature reading in the point of measurement. The device has been designed in accordance with standards for smoke detectors using light beams and short-circuit isolators in fire alarm systems (EN 54-7 and EN 54-17). The principle of the device operation is based on optical engineering.

Heat detector

Heat detectors are used mainly in rooms where traditional smoke detectors will not work. Such situation may be present at premises where smoke is a normal phenomenon. Heat detectors may react when the ambient temperature grows to a specific level or when a fast growth of temperature is detected within a specific period of time.

Multi-sensor detector

A multi-sensor, addressable detector connects the functions of a smoke detector and a temperature detector. The device operates in an active manner, which means that a growth of temperature results in increasing the sensitivity of the smoke detector. This solution ensures fast reaction of the fire alarm system independently. The device has been designed in accordance with standards for smoke detectors using light beams and short-circuit isolators in fire alarm systems (EN 54-7 and EN 54-17). The principle of the device operation is based on optical engineering.

wireless fire detector

Wireless fire detector

Wireless fire detectors are available in three versions operating based on a heat sensor, optical sensor or an optical-and-heat sensor, which combines the features of the former two. All of the sensors are fully addressable and compatible with all of the expanders (signal intensifiers) and translators by Argus. The applied algorithms ensure optimal operation of the detectors by eliminating false alarms. Thanks to very low energy consumption, the device may operate up to 8 years on one set of batteries.

aspirating smoke detector

Aspirating smoke detector

Aspirating smoke detectors are intended for spaces where early fire detection and alarm are of particular importance. In such detectors air is aspirated from the monitored area through a system of tubes, and further analysed by the central unit. The sensors of the detector discover even the smallest quantity of smoke, which additionally shortens the fire alarm system reaction time. Such detectors are usually installed in laboratories, large and open spaces, archives or historic buildings.

line smoke detector

Line smoke detector

Line smoke detector may replace several or several dozens of traditional smoke detectors. The solution is particularly useful in large-space structures or when the installation of a large number of traditional detectors is difficult (e.g. very high ceiling). Basic elements of the detector are a transmitter and a receiver. The transmitter emits a narrow band infrared light, which is directed towards the receiver. At the moment smoke particles get into the path of the beam, the alarm is triggered.

line temperature detector

Line temperature detector

Line temperature detector is a special active cable with embedded sensors. The solution is intended to be applied in hardly accessible spaces or when temperature measurement is required along long sections reaching from several dozens to several thousands meters. The line temperature sensor precisely indicates the source of fire or overheating of the monitored equipment or cable route. The system does not require calibration but still works with very high accuracy (± 0.1°C). It is the first in Poland line temperature detector compliant with the Polish Standard PN-EN 54-22 (line-type heat detectors as elements of fire alarm systems). It is important that the system may be used in hazard explosion zones.

voice alarm systems

Voice alarm systems (VAS)

Voice alarm systems may be used both in closed spaces and in open space. The devices have been designed such that the emitted sound is loud, clear and audible from great distances. The system is supplied with such accessories as microphones or audio frequency amplifier. Voice alarm systems serve to transfer messages during a fire, which facilitates the evacuation of people. At the moment there is no hazard, the system may be used as a traditional loudspeaking system.

wireless alarm sounder audible and visual alarm system

Wireless alarm sounder/ audible and visual alarm system

Fire is signalled through wireless alarm sounders or audible and visual alarm systems. The devices comply with the standard requirements for fire alarm systems and visual alarms in fire-fighting systems. The device is resistant to weather conditions. It has 32 sounds and a mute mode, in which it will only operate as a visual alarm. Thanks to the incorporated microphone it is capable of detecting proper operation when the alarm is sounded and return an error information to the system. The device installation is very fast and simple, and the use of the same generates very low costs.

manual call points

Manual call points

Addressable manual call points are supplied in standards adequate to the working conditions. They are important elements of fire alarm systems (FAS), therefore, the solutions we propose guarantee fast reaction in a time shorter than 3 seconds. The devices have a self-test mode, which is started automatically every day. They are designed and manufactured in accordance with the EN 54-11 standard applicable to manual call points in fire-fighting systems.
