Why is the smoke removal system so important?
Smoke removal systems in buildings are one of the elements of greatest importance for human safety in the event of a fire. The smoke generated during a fire poses a serious threat to the health and life of people inside the building. Effective smoke removal systems enable the removal of smoke along with poisonous gases and heated air outside the building, thus facilitating safe evacuation.
The health and life of building users depend on the efficiency and reliability of the smoke removal system. Therefore, they should be properly maintained and designed. It is also necessary to choose the appropriate type of system - there are gravitational and mechanical variants. How do they differ from each other? What elements do they consist of? What should you pay attention to when choosing a specific solution?
How does the smoke removal system work?
The principle of operation of the building smoke removal system depends on its type. The gravity method uses natural air flow resulting from the pressure difference. Thanks to this, such systems are easy to implement and relatively cheap. In turn, the mechanical method is based on the operation of a set of fans, sensors and other components used to actively remove smoke and air from the interior of the building.
Regardless of the type of system, their task is to remove smoke from the interior of the building. Particular emphasis is placed on smoke removal from staircases and escape routes, i.e. areas of key importance for effective evacuation during a fire. Requirements for smoke removal from staircases are regulated by building regulations and standards. They should be taken into account already at the stage of building design or renovation planning.

The block diagram of connections to actuators shows well. It shows that individual system elements are connected to executive devices (we write more about them in the next paragraph). The following are connected to the control panel:
- smoke vents and windows;
- emergency doors and gates;
- fire and comfort fans;
- smoke exhaust buttons ;
- fire and household flaps;
- magnetic grippers.
What are the elements of a smoke removal system?
Efficiently operating actuators of smoke removal systems in buildings consist of several cooperating segments. These are:
- a visualization segment consisting of signaling elements such as lamps, monitors or sound signals;
- power segment;
- control, power supply and monitoring segment of fire dampers. together with gas detection devices, pressure sensors and other accessories;
- control and power supply segment for fire protection fans. and living;
- segment of control, power supply and monitoring of other devices;
- connection segment to the SSP and SO system with inputs and outputs to the smoke exhaust and SSP systems.
