What are the components of a fire alarm system?
Generally, automatic fire alarm system consists of two parts: fire detector and fire alarm. Fire detectors are installed on site to monitor fire alarms, fire alarms are installed in fire control centers and all fire detectors are managed. When a fire alarm is detected, a sound light warning signal is sent to notify the duty officer, and some fire alarms can also start the linkage device to extinguish the fire. Some fire detectors are equipped with sound and light alarm devices, which can be used outside the fire alarm and are generally used in families.
Automatic fire linkage system is used to control all kinds of linkage equipment. There are multi line linkage control system and bus linkage control system. Multi line linkage control system, from the linkage controller to each linkage equipment should connect 2 -6 lines, generally applicable to less linkage equipment building. For more linkage equipment, if the use of multi line linkage control system, the construction of the project is more difficult, it is best to use the bus linkage control system.
In the bus linkage control system, the automatic fire linkage system consists of linkage controller and control module. In the linkage between the controller and the control module for two bus and four bus, each bus can connect a plurality of control modules, the need to start the linkage equipment, linkage controller sends a start command, control module, control module restarting linkage equipment. Generally a linkage device for an action, but some equipment, such as rolling doors for the two action. Some modules output an action, and some outputs a number of actions. At design time, it is necessary to determine that the linkage requires several modular controls.
