How Do I Choose the Best Fire Alarm Bell?

Automatic fire alarm. In the early stage of the fire, the physical quantities such as smoke, heat and light radiation generated by the combustion are converted into electrical signals by fire detectors such as temperature, smoke and light, and transmitted to the fire alarm controller. Record the time of the fire at the location.

Automatic fire alarm

With the development of China's modernization, the construction of various types of industrial buildings is accelerating. In the process of construction, especially the prevention of fire is becoming more and more important. The National Fire Protection Law has promulgated and implemented relevant laws and regulations, and the prevention of fire in engineering construction has been raised to the height of the law. The principle of "prevention-oriented, combination of prevention and elimination" required by the fire protection system also signifies that the automatic fire alarm system will play a more important role. The automatic fire alarm system is a type of installation in buildings or other places in order to let people detect fires early and take effective measures to control and extinguish fires in a timely manner.

Automatic fire alarm system is made up of

(1) Fire alarm: When receiving a fire alarm signal from the detector, manual alarm switch, fire hydrant switch and equipment connected to the input module, it can alarm in the alarm.

(2) Fault alarm: When the system is running, the controller will perform time-based inspections. If there is an abnormality (equipment failure), it will issue audible and optical alarm signals, and display the fault type and code.

(3) Fire alarm priority: When a fault alarm or fire alarm has been processed, a fire alarm will be reported if a fire alarm occurs, and the original fault will be automatically reported when the fire alarm is cleared.

(4) Memory of clock and fire occurrence time: The clock travel time in the system is realized by software programming, with corresponding storage unit to memorize the accident occurrence time.

(5) Self-check function: In order to improve the reliability of the alarm system, the controller is equipped with a check function, which can perform simulated fire alarm inspections regularly or irregularly.
