How does the fire fighting system work in the building?
Fire fighting equipment is basically composed of fire alarm system and fire extinguishing system, such as automatic sprinkler system, gas fire extinguishing system, foam extinguishing system, etc.Manual and automatic operation.The starting mode is that the smoke detector detects the fire and sends a signal to the control host, which is controlled by the control host to start the relevant equipment.
Gas fire extinguishing pipe network system has more than a mechanical start, no pipe network, no mechanical start, because people can not run into the fire, to start the machine.The gas fire extinguishing system is also started by the control host after the signal is sent by the alarm system or started manually. The fire extinguishing system is delayed starting because of the high speed of fire and the danger of fire.
Wet automatic sprinkler system in the quasi working state, a temperature sensing glass column its nozzle, a glass column reaches a certain temperature on the burst and water spray, so the reaction is often slower than the detector, detector has issued a warning signal for a period of time, to reach the temperature of the water starts here.. Dry automatic sprinkler system is sent through the detector signal, and then started the pumps, exhaust devices and other equipment, the water is filled with water pipes before they begin to work.
