The origin and progress of the fire is detected and followed by one or more fire alarms (8) incorporating one or more electrochemical and semiconductor gas sensors (1,2) of the same or different design, which identify one or more different types of gas. The origin and progress of the fire is detected and followed by one or more fire alarms (8) incorporating one or more electrochemical and semiconductor gas sensors (1,2) of the same or different design, which identify one or more different types of gas. An Independent claim is also included for a system for fire detection, comprising ionization smoke detectors and flame detectors. The system has electrochemical sensors for CO (1) and HCN (2), a semiconductor gas sensor (3) for the detection of flammable gases, a temperature sensor (4), smoke gas detectors (5), a microprocessor (6), a data storage system (7), fire alarm (8), a fire extinguishing system (9), and a display system (10).
