What are the common fire fighting equipment?

Common firefighting equipment includes:
1. Automatic sprinkler system: It is composed of sprinkler heads, alarm valve groups, water flow alarm devices (water flow indicator or pressure switch) and other components, as well as pipelines and water supply facilities, and can spray water in the event of fire. Automatic fire extinguishing system. It is composed of wet alarm valve group, closed nozzle, water flow indicator, control valve, terminal water test device, pipeline and water supply facilities.

2. Foam fire extinguishing system: refers to a fire extinguishing measure consisting of a complete set of equipment and procedures. It consists of a fixed foam liquid fire pump, a foam liquid storage tank, a proportional mixer, a conveying pipeline for foam mixed liquid and a foam generating device, etc., and is integrated with the water supply system. When a fire occurs, first start the fire pump and open the relevant valves, and the system can put out the fire.

3. Manual fire alarm button: It is a type of equipment in the fire alarm system. When a fire occurs, when the fire detector does not detect the fire, the personnel manually press the manual fire alarm button to report the fire signal.

4. Thermal fire detector: It mainly uses thermal elements to detect fire. In the initial stage of the fire, a large amount of smoke is produced on the one hand, and on the other hand, the material releases a lot of heat during the combustion process, and the surrounding temperature rises sharply. The thermal element in the detector undergoes physical changes and responds to abnormal temperature, temperature rate, and temperature difference, thereby converting the temperature signal into an electrical signal and performing alarm processing.

5. Fire broadcast system: also called emergency broadcast system, is an important equipment for fire escape and evacuation and fire fighting command, and plays an extremely important role in the entire fire control management system. In the event of a fire, the emergency broadcast signal is sent out through the audio source device, and after power amplification, the broadcast switching module switches to the speakers in the designated broadcast area to achieve emergency broadcast.

Fire extinguishing equipment includes heptafluoropropane fire extinguishing device, carbon dioxide fire extinguisher, 1211 fire extinguisher, dry powder fire extinguisher, acid-base foam fire extinguisher, carbon tetrachloride fire extinguisher, fire extinguisher hanger, mechanical foam fire extinguisher, water fire extinguisher, and other fire extinguishing appliances.
