Centralized fire alarm controller is an important part of the automatic fire alarm system, which has a variety of functions such as fire alarm and linkage, which can effectively monitor and prevent the occurrence of fire accidents. Today I will teach you how to distinguish between them.
Fire alarm function
The fire alarm function is one of the core functions of the centralized fire alarm controller, which can detect the fire signal through the detector, send out the fire alarm in time, and display the fire alarm location and alarm time and other information. The centralized fire alarm controller generally has the following fire alarm functions:
1.Area alarm: When the detector detects a fire signal, the controller will send an alarm signal in the corresponding area to remind the relevant personnel to deal with it in time.
2.Bus alarm: When the detector detects a fire signal, the controller will send an alarm signal on the bus to remind the relevant personnel to deal with it in time.
3.Fire Priority: When multiple fire alarms occur at the same time, the controller will prioritize the fire alarm that occurs first to ensure timeliness and safety.
4.Manual alarm: When an emergency occurs, the relevant personnel can issue a fire alarm by manually triggering the alarm button or panic button on the controller.
Linkage function
The linkage function means that the centralized fire alarm controller can control the relevant fire protection equipment through the output module, such as fire broadcasting, fire fans, fire pumps, etc. When a fire breaks out, the controller can automatically or manually start the relevant fire-fighting equipment according to the pre-set program to achieve the purpose of fire extinguishing and rescue. The centralized fire alarm controller generally has the following linkage functions:
1.Automatic linkage: In the event of a fire, the controller can automatically start the relevant fire-fighting equipment according to the pre-set program. For example, when a fire occurs, the controller can automatically turn on the fire broadcast, ** evacuation command, and start the fire fan and fire pump and other equipment at the same time to extinguish the fire.
2.Manual linkage: When a fire occurs, the relevant personnel can start the relevant fire-fighting equipment by manually operating the linkage button or input module on the controller. For example, when a fire occurs, relevant personnel can manually operate the linkage button of the controller to turn on the fire broadcast, ** evacuation instructions, and start the fire fan and fire pump and other equipment to extinguish the fire at the same time.
3.Fault alarm: When the relevant fire-fighting equipment fails, the controller will send out a fault alarm signal to remind the relevant personnel to repair and deal with it in time. For example, when the fire pump fails and cannot work normally, the controller will send a fault alarm signal through the output module to remind the relevant personnel to repair it in time.
4.Linkage feedback: When the relevant fire-fighting equipment is started, the controller will receive the feedback signal of the equipment through the input module to display the working status and location information of the equipment. For example, when the fire broadcast is started, the controller will receive the feedback signal of the broadcast through the input module to display the working status and position information of the broadcast.
Methods of differentiation
The fire alarm and linkage functions of the centralized fire alarm controller can be distinguished by the following methods:
1.Functional identification: On the panel of the centralized fire alarm controller or in the operation manual, the corresponding functional identification or icon is usually marked to facilitate the identification and use of relevant personnel. For example, a "fire" logo or a red alarm icon indicates a fire alarm function, and a "linkage" logo or a green linkage indicates a linkage function.
2.Mode of operation: Different functions often have different ways of operation and processes. For example, the operation of a fire alarm function usually requires the pressing of an alarm button or the triggering of a panic button on the respective detector, while the operation of a linkage function usually requires the pressing of a linkage button on the corresponding device or control via an input module.
3.Sound prompt: In the automatic fire alarm system, different sound prompts can also be used to distinguish between fire alarm and linkage functions. For example, when a fire alarm occurs, the centralized fire alarm controller will emit a high-decibel alarm sound or broadcast a prompt sound to remind the relevant personnel to deal with it in time;In the event of a linkage event, the centralized fire alarm controller will not sound an alarm or broadcast a sound.
4.Display interface: The display interface of a centralized fire alarm controller usually displays corresponding information and icons for easy viewing and understanding by relevant personnel. For example, information such as the location and time of a fire alarm is displayed on the display screen, as well as the status and location of related firefighting equipment.
