With the continuous development of microprocessor technology, sensing technology, communication technology, control technology and artificial intelligence technology, the main development directions of fire detection and alarm systems in the future will increasingly be high reliability, low false alarm rate and network. And intelligent development.


The automatic fire alarm system can convert the physical quantities such as smoke, heat, and flames generated by the combustion into electrical signals through the fire detector and transmit them to the fire alarm controller. At the same time, the fire layer and the upper and lower floors are notified by sound or light The evacuation of the adjacent layer, the controller records the location and time of the fire, so that people can find the fire in time and take effective measures in time to put out the initial fire and limit the loss of life and property caused by the fire.


At present, the automatic fire detection and alarm system is widely used, and has become a device in many places, which has played a supporting role. However, in the practical application of the fire detection and alarm system, many problems have also occurred. The quality of existing products in the market is uneven, there is a single product function, and the reliability and stability are not high; only detecting a certain type of fire parameters, errors occur. Many issues such as false negatives. With the continuous development of microprocessor technology, sensing technology, communication technology, control technology and artificial intelligence technology, the main development directions of fire detection and alarm systems in the future will increasingly be high reliability, low false alarm rate and network. And intelligent development. Intelligent wireless fire alarm system is the main research direction.


Fire alarm system is generally composed of trigger device, fire alarm device, linkage output device and other auxiliary function devices; it can also be linked with various fire extinguishing facilities and communication devices according to the requirements of the project to form a central control system. That is, a complete fire control system is composed of automatic alarm, automatic fire extinguishing, evacuation induction, system process display, and fire file management.


Trigger device


In the automatic fire alarm system, devices that automatically or manually generate a fire alarm signal are called triggers, which mainly include fire detectors and manual fire alarm buttons. A fire detector is a device that can respond to fire parameters (such as smoke, temperature, flame radiation, gas concentration, etc.) and automatically generate a fire alarm signal. According to the different fire response parameters, fire detectors are divided into five basic types: thermal fire detectors, smoke fire detectors, photosensitive fire detectors, combustible gas detectors, and composite fire detectors. Different types of fire detectors are suitable for different types of fires and different places. The manual fire alarm button is a device that manually generates a fire alarm signal and starts an automatic fire alarm system, and is also an indispensable part of the automatic fire alarm system.

Fire alarm

In an automatic fire alarm system, a control instruction device used to receive, display, and transmit fire alarm signals, and can issue control signals and other auxiliary functions is called a fire alarm device. The fire alarm controller is one of the basic ones. 监视探测器及系统自身的工作状态;接收、转换、处理火灾探测器输出的报警信号;进行声光报警;指示报警的具体部位及时间;同时执行相应辅助控制等诸多任务。 The fire alarm controller is responsible for providing a stable working power supply for the fire detector ; monitoring the working state of the detector and the system itself ; receiving, converting, and processing the alarm signals output by the fire detector ; performing audible and visual alarms ; indicating the specific parts of the alarm and Time ; simultaneously perform many tasks such as corresponding auxiliary control. It is a core component of a fire alarm system.

In the fire alarm device, there are some alarm devices with incomplete functions such as interrupters, area displays, and fire display panels, which can be regarded as the evolution or supplement of the fire alarm controller. Under specific conditions, it belongs to the same fire alarm device as the fire alarm controller.

The basic functions of the fire alarm controller are: automatic conversion of main power and backup power, backup power supply charging function, power failure monitoring function, power supply status indicator function, power supply for the detector loop, sound or light alarm of the controller or system failure , Fire sound, light alarm, fire alarm memory function, clock unit function, fire alarm priority reporting function, sound alarm sound mute and re-audible alarm function.
