Fire alarm system is also called fire alarm system and automatic fire alarm system.
It consists of a fire alarm host, a fire characteristic or early fire characteristic sensor, an artificial fire alarm device and an output control device.
The sensor completes the detection of fire characteristics or early fire characteristics, and transmits relevant signals to the fire alarm host.
The alarm host completes the display and recording of signals and the corresponding output control.
The automatic fire alarm system is an automatic fire-fighting facility set up in buildings or other places in order to find and report fires as early as possible and take effective measures to control and extinguish them in time. It is a powerful tool for people to put out fires.

1) The scope of building fire protection design is very wide, and it is a comprehensive problem of many disciplines. Moreover, the larger the building scale, the more functions and the more complicated the control project. Therefore, in modern building facilities, fire protection design must adopt mechanization and automation as much as possible, and adopt fast and reliable control methods to minimize fire losses.
2) In system design, we should also pay attention to giving priority to domestic equipment as much as possible under the same conditions, and don't easily introduce foreign equipment unless necessary. First, foreign products are generally more expensive, need foreign exchange, and it is inconvenient to maintain in the future and easy to be controlled by others.
Moreover, domestic products are constantly improving, and their performance indicators and technical level are not worse than those of foreign countries. Adopting domestic equipment is conducive to promoting the development of national industries and saving a lot of foreign exchange. This cannot be ignored.
3) The current national standards and codes that should be followed in system design mainly include Code for Design of Automatic Fire Alarm System (GB50116-98), Code for Fire Protection Design of High-rise Civil Buildings, Code for Fire Protection Design of Buildings, Code for Fire Protection Design of Civil Air Defense Engineering, Code for Design of Power Supply System of Industrial and Civil Buildings, etc.
4) The design of the system must be undertaken by the design unit recognized and approved by the relevant state departments.
5) The pre-design work shall be carried out as follows
(1) Understand the basic situation of the building, including the nature, specifications, functions and individual aspects of the building; Fire division, fire prevention measures, structural forms and decorative materials of building structure specialty; Elevator configuration and management, well layout; Layout, nature and use of various computer rooms and warehouses.
(2) Understand the relevant professional fire-fighting facilities and requirements, including the setting of air supply, exhaust and air conditioning systems; The setting of smoke control system and the requirements of electrical control and interlock; Setting of fire extinguishing system (fire hydrant, automatic sprinkler system and halon system).
Electrical control and interlock requirements; Installation and electrical control requirements of fire shutter doors and fire doors: power supply, power distribution system, lighting, power supply control and coordination of fire zones; Configuration of fire power supply, etc.
(3) Make clear the design principles, including determining the classification level and protection mode of building fire protection according to the specification requirements, formulating the scheme of automatic fire protection system, and fully grasping the technical performance and requirements of various fire protection equipment and alarm equipment.
Coexisting fire fighting force system.
1, public security fire brigade. The public security fire brigade is a part of the public security organs, with a total post of nearly 1, 246,57. Active service, included in the Chinese People's Armed Police Force sequence, enjoy the same treatment as the China People's Liberation Army. It is the main force of fire prevention and rescue in China.
Note: In some economically developed areas, local governments have established non-active public security fire fighting teams by increasing the establishment of administrative public security, and their personnel enjoy the treatment of the people's police. At present, there are over 950 people in China.
2, the local government full-time fire brigade. According to the form of "government investment, various systems, open recruitment and public security management", full-time firefighters are recruited by contract, and local government full-time fire brigades are formed, with about 654.38+0.0000 people.
3, enterprises and institutions full-time fire brigade. Airports, ports, oil fields, power plants and other large enterprises and institutions with high fire risk have full-time fire brigades. There are 76,000 people in * * * nationwide, who are mainly responsible for the internal fire fighting tasks of the unit.
Fire fighting is a very social work. Only by relying on the strength of the whole society and with the care, concern, support and participation of all members of society can we do a good job in fire fighting.
Sociality of fire fighting tools; Fire control management should penetrate into all fields of human life and harvest, thus determining the sociality of fire control work; Fire safety management involves all walks of life, even thousands of households. In the process of production, work and life, people neglect fire safety management slightly. If they are absent-minded, out of control and make mistakes in production, they may cause fires, which determines the regularity of fire control work.
Looking at the lessons of fire accidents over the years, although the causes of disasters are complex, we can see that most fires are caused by one person's mistake, which further clarifies a truth. Only with the active participation of the people can the occurrence of fire accidents be controlled and eliminated, which in turn determines the mass of fire control work.
