Structure and working principle of fire alarm devices
This paragraph Dong Nam fire Southeast introduces the structure and operating principle of the fire protection equipment. When dangerous fires and explosions often occur, the presence of fire alarm devices is extremely necessary, thanks to the timely warning whenever a fire or explosion occurs so that everyone can detect it in time to escape. or call the fire center promptly. In this article, we will learn together about the working principle of fire alarm devices.
1. Fire detector
Currently, there are two types of fire detectors that are automatic fire detectors and thermal fire detectors. Heat detectors also have fixed heat detectors and increased heat detectors. Heat detectors are popularly used by many people, when the ambient temperature rises to a fixed level installed inside the heat detector, they will immediately send a signal and send it to the center. Heat detectors are divided into 3 groups of levels a, b and c. for group a with temperature from 60 to 75, group b from 80 to 95, and group c from 120 to 135, if the temperature change outside the environment only increases to 2 degrees c/min, the detector will not working, thus minimizing false alarms, not confusing the user..
2. Central cabinet and automatic fire alarm system
For central cabinets and automatic fire alarm system, it is a device used to detect locations of fire and explosion, with the task of quickly and accurately reporting where a fire occurs. When the system is in standby mode, the system always has a signal mode to check the working of those devices and also respond to the hub. Periodically, from time to time (depending on the level we set) the center will print the status of the system and information about the equipment that needs maintenance, so it can be completely assured and used. When the device is in monitoring mode, if there is a problem, the center will receive an error signal, or if there is no response from the device, the center will operate in the fault mode. Information about the incident will be displayed on the screen. After the error has been fixed, the device will end the trouble mode and return to the normal monitoring mode.
Here is the structure and working principle of some fire protection equipment, you can learn and know more information about it so that you can improve the efficiency every time you use it, avoiding ignoring the uses of these devices. If there is a need to buy or install fire alarm systems, please come to Dong Nam Pccc immediately.
