What is an automatic fire alarm system?

The automatic fire alarm system consists of trigger device, fire alarm device, linkage output device and other auxiliary functional devices. It can convert the physical quantities such as smoke, heat and flame produced by combustion into electrical signals at the early stage of fire, and transmit them to the fire alarm controller, at the same time, it can inform the whole floor to evacuate in the form of sound or light. The controller records the location and time of fire, so that people can find the fire in time and take effective measures to put out the initial fire in time. The statistics of relevant data show that, under normal circumstances, any place with automatic fire alarm system can give an alarm as soon as possible when a fire occurs, which will not lead to a major fire. In many important office buildings, warehouses, substations and control centers of China's transportation and shipping system, all kinds of ships with a gross tonnage of more than 500 tons have installed automatic fire alarm systems in accordance with the national standards "Code for Fire Protection Design of High-rise Civil Buildings", "Code for Fire Protection Design of Buildings" and SOLAS Convention of the International Maritime Organization, which has played an important role in fire safety and security.
