What are the types and components of automatic fire alarm system?

The area alarm system consists of mountain fire detector, manual alarm, area alarm controller or general alarm controller, fire alarm device, etc. This system is mainly used to complete fire detection and alarm tasks, and it is suitable for R small building objects and fire prevention objects to be used alone. In general, there should be no more than three regional fire alarm controllers or three small general fire alarm controllers for regional alarm in the fire detection and alarm area where the system is used. The form of centralized alarm system should be considered. 2. Centralized alarm system The centralized alarm system consists of a fire detector, a regional fire alarm controller or a general fire alarm controller and a centralized fire alarm controller for civil alarm. This system is suitable for high-rise hotels, office buildings and other fire protection objects. 3. Alarm system of control center The alarm system of control center is composed of fire linkage control device, centralized fire alarm controller, regional fire alarm controller and various fire detectors set in the fire control center (or fire control room), or it is composed of fire linkage control device, multiple general fire alarm controllers arranged annularly and various fire detectors and functional modules. The automatic fire alarm system can be divided into the above two basic design forms according to the different building characteristics and fire alarm controllers, and can also be divided into two system application forms: multi-line system and bus system according to the connection mode of fire detectors, various functional modules and floor displays. According to the structural design and electronic circuit design of the fire detector itself, and the different signal transmission and processing methods between the fire detector I and the alarm controller, the bus system is further divided into two bus systems and multi-bus system application forms.
