Fire safety measures, including smoke control and ventilation systems, are vital in the event of a fire to ensure the safe evacuation of building occupants and easy access for the fire service. The crucial role that each element and system plays means that any failure or inefficiency could endanger both the lives of the occupants and the building itself. Fire and smoke control systems are often complex due to a range of factors, including the physical characteristics and use of the building, which will influence the specifications of the system. The long-term effectiveness and compliance of the installed solution will depend on the quality of design, installation, testing and commissioning. It is also based on comprehensive periodic maintenance throughout its life. A fire detection system aims to detect and report the onset of a disaster as soon as possible, in order to reduce the time required to implement firefighting measures and to limit its impact.
