The smoke control system is designed to extract combustion products – smoke and heat – from the building. This facilitates the safe evacuation of occupants, minimizes material losses, and enhances the efficiency of rescue and firefighting operations.
During the inspection, we verify the technical condition of the equipment, control mechanisms, power supply, actuators, and the system's response to signals from smoke detectors and manual smoke vent buttons (RPO). We examine both electric and pneumatic systems, and all completed work is formally documented in reports for the State Fire Service (PSP) and the insurance provider.
We inspect smoke vents, windows, actuators, control panels, and other control components, irrespective of whether the system operates on an electric or pneumatic drive.
We conduct activation tests initiated by smoke detectors, manual RPO buttons, and the fire alarm system (FAS), verifying response times and the full opening of smoke vents.
We continuously adjust actuators, locking mechanisms, limiters, and control settings, ensuring the system is operational without additional downtime.
Upon completion of the inspection, you will receive a full set of reports, entries into the fire safety documentation, and recommendations for any necessary repairs or upgrades.
A smoke control system is designed not only to extract smoke to the exterior but also to introduce fresh air into the evacuation zone. This ventilation creates a controlled airflow, where smoke and hot gases are extracted from the upper levels, and cooler external air is drawn in from below. If smoke is not effectively removed, it accumulates and elevates the ambient temperature. Conversely, with a properly functioning smoke control system, the influx of fresh air reduces the temperature, resulting in less smoke in corridors and stairwells, improved visibility for occupants and firefighters, expedited evacuation, and a more straightforward localization of the fire source.
Mechanical ventilation is implemented using supply fans, dampers, and throttles controlled from the smoke control panel. The system injects an appropriate volume of air into the building, maintaining positive pressure in stairwells, lobbies, and corridors. This effectively prevents smoke ingress into evacuation routes and enhances the efficiency of smoke extraction through vents and exhaust shafts.
Natural smoke ventilation utilizes the natural air draft created by opening doors, vents, and windows in the lower sections of stairwells, passages, or garages. Temperature and pressure differentials cause fresh air to be drawn in naturally, while smoke rises and is exhausted through smoke vents.
Smoke ventilation systems are mandated by the Regulation of the Minister of Infrastructure of April 12, 2002, concerning the technical conditions to be met by buildings and their location. In practice, this entails the obligation to implement smoke exhaust devices, among others, in the following facilities:
e.g., public facilities designed for individuals with limited mobility.
with ZL I, ZL II, ZL III, or ZL V fire zones.
in fire zones other than ZL IV, technical and construction solutions are implemented to protect horizontal escape routes from smoke.
if commercial and service premises adjoin them, solutions preventing smoke ingress into escape routes are required.
with rooms for 100 or more people – solutions preventing smoke ingress into escape routes and the room itself are implemented.
stairwells and fire-rated lobbies that are part of an escape route must be equipped with smoke prevention devices.
should be equipped with smoke prevention devices or automatic smoke exhaust systems controlled by a smoke detection signal.
(production and storage facilities) with a fire load density exceeding 500 MJ/m² or with explosion-hazard rooms – enclosed, lockable stairwells equipped with smoke prevention or smoke exhaust devices are required.
We inspect smoke ventilation systems based on electric actuators, controlled from a smoke control panel. We check wiring, primary and emergency power supply, connection integrity, and communication with smoke detectors, RPO buttons (manual call points), and the fire alarm system (FAS). We perform opening tests for smoke vents and windows, assessing the system's response time and the full opening of the sashes. If necessary, we adjust actuators, hinges, and controller parameters to ensure proper device operation in an emergency.
In pneumatic systems, we inspect the condition of the CO₂ installation, gas cartridges, lines, distributors, and pneumatic actuators. We check smoke zone control panels and autonomous systems responsible for opening individual vents. We test system activation from manual call points, thermal elements, and smoke detectors, then assess whether the vents open to their full extent. The report details the installation's condition, cylinder fill levels, and recommendations for replacing consumable components.
Initially, we review the technical documentation of the facility and its existing smoke control system. We verify the quantity and placement of smoke dampers, windows, control panels, and other control components, as well as the applicable regulatory requirements for the specific building category.
We conduct a comprehensive inspection of all system components – from actuators and smoke dampers, through control panels, to smoke detectors and manual smoke control activation buttons (RPO). We perform operational tests, verify the opening time of the dampers, and make necessary adjustments to ensure the system operates reliably and consistently.
Upon completion of the inspection, we prepare detailed reports and update the system documentation. We identify any components requiring repair or modernization. For ongoing service contracts, we proactively remind clients of upcoming inspection dates and provide support in adapting the system to current regulatory requirements.
