3. Connect the additional cable wire to the normally open contact.

4. After wiring is complete, securely close the lid and tighten the screws to restore to original condition.

49. Working Principle of High-Pressure Fine Mist Open System: In the standby condition, the fine mist system maintains a certain pressure within the pipeline from the pump group outlet to the control valve box of the division. When the pressure drops below the set starting pressure of the pressure maintenance pump by 1Mpa, the pressure maintenance pump activates, ensuring the pipeline of the system maintains a stable pressure of (1-1.2) MPa.

50. High-pressure fine water mist open system working principle: Upon detection of a fire signal by the detector, the fire alarm control main unit transmits the signal to the electric ball valve within the pump group control cabinet and the electric ball valve in the zoning control valve box. The high-pressure plunger pump automatically starts up, and the electric ball valve in the zoning control valve box opens. High-pressure water then forms a mist through pipes and nozzles to extinguish the fire.

51. High-pressure fine mist open system working principle: The pressure switch feedback system in the zoning control valve box sends out a spray signal, and upon receiving this feedback signal, the main unit联动ly activates the spray indicator light.

52. High-pressure fine mist closed system working principle: In the standby condition, the fine mist system maintains a certain pressure within the pipeline network from the pump group outlet to the control valve box. When the pipeline pressure drops and falls below the 1MPa set start-up pressure of the pressure maintenance pump, the pump is activated to keep the system pipeline at a stable pressure of 1-1.2MPa.

53. High-pressure Fine Mist Closed System Working Principle: Upon detecting a fire signal, the fire alarm control main unit transmits a signal to the pump group control cabinet. The high-pressure plunger pump starts up, and the electric ball valves inside the zone control valve box open. The entire pipeline is filled with high-pressure water. Once the temperature of the glass balls in the closed heads reaches the activation temperature, the glass balls shatter, and the high-pressure water forms a mist through the nozzles for fire extinguishing.

54. High-pressure fine mist closed-loop system working principle: The pressure switch feedback system in the zone control valve box sends out a release signal, upon which the main unit receives the feedback signal and联动ly activates the spray indicator light.

55. Automatic activation of high-pressure fine water mist system: When a fire occurs within the protected area, the fire detector detects the fire and sends a signal to the fire alarm controller. The fire alarm controller confirms the area of the fire based on the address of the fire detector, then sends a control signal to activate the fire extinguishing system, starting the high-pressure plunger pump and opening the corresponding section control valves.

56. Automatic startup of high-pressure fine mist system: After the division valve is opened, water in the system pipes quickly reaches working pressure (closed pre-action system waits for the closed spray head to sense the burst temperature, then the glass ball automatically bursts), and sprays through high-pressure fine mist nozzles to create a misting effect, producing fine mist to extinguish fires.

57. High-pressure fine mist system manual electrical start: Remote start: When a fire is detected, before the fire detector activates, the electric valve button on the corresponding zone control valve box can be activated remotely from the fire control center to initiate the zone valve, allowing the pump to automatically start and supply water for fire extinguishing.

58. High-pressure fine mist system manual electrical start: On-site start: When a fire is detected, the local section control valve box can be opened to activate the area valve by pressing the control button, for fire extinguishing purposes.

59. Mechanical emergency start of high-pressure fine mist system: In the event of failure of the fire alarm system, the handle on the area valve can be manually operated to open the area valve for fire extinguishing. Note: The emergency start of a closed fine mist system can be achieved by breaking the glass ball of the closed nozzle.

High-pressure fine mist is produced by professional equipment under low design working pressure, forming a mist with a droplet accumulation distribution of Dv0.99 < 300μm on a plane 1m from the nozzle. High-pressure mist has functions such as cooling, humidifying, dust suppression, fire prevention, and landscaping, and can be used in industries, animal husbandry, agriculture, entertainment, and other fields.

61. Fire Extinguishing Mechanism of High-Pressure Fine Water Mist: Rapid Cooling and Local Asphyxiation—Advanced Dual-Action Fire Extinguishing Mechanism: Water is emitted from a nozzle of a special material in the form of mist with particle sizes ranging from 10 to 100 micrometers, having a smaller surface area. Upon contact with fire, it quickly vaporizes, expanding in volume by 1700 to 5800 times, absorbing a large amount of heat and rapidly lowering the temperature of the burning surface; simultaneously, the vaporized water forms steam, enveloping and covering the entire combustion area, causing the fire to suffocate due to lack of oxygen.

62. Fire extinguishing mechanism of high-pressure fine water mist: The heat absorption is calculated based on the latent heat of water evaporation at 100℃ as 2257 kJ/kg. Each fine water mist nozzle absorbs heat at a rate of approximately 300 kW for every 1 kg of fine water mist emitted, demonstrating its high heat absorption rate and strong cooling effect.

63. Suppression Mechanism of High-Pressure Fine Water Mist Fire Extinguishing: Aspirating action - when the fine water mist is heated, it vaporizes and expands dramatically to 1700~5800 times its original volume, creating a dense cloud of steam that envelops the burning material, forming a barrier that blocks the entry of fresh air. This deprivation of oxygen causes the combustion to cease.

64. The fire suppression mechanism of high-pressure fine water mist: After the fine water mist evaporates, the resulting steam quickly envelops the burning material, flame, and smoke, effectively blocking the radiant heat of the flame, preventing the spread of the fire.

65. Suppression Mechanism of High-Pressure Fine Water Mist Fire Extinguishing: The high-pressure fine water mist not only has the effect of smoke and dust removal but also cleans smoke and debris. This is because the ash, carbon particles, and harmful gases from the burning are neutralized by sticking to the fine water droplets. According to statistics, 70% of fire-related deaths are not caused by direct fire burns but by inhaling toxic gases and smoke from high temperatures.

66. The extinguishing mechanism of high-pressure fine water mist: It can extinguish oil fires through wetting action. The high-speed mist particles can penetrate the surface of burning oil materials, wetting them and preventing the further generation of flammable gases. Additionally, due to the small size of the mist particles, they do not disturb the liquid surface, causing splashes, thereby achieving the purpose of extinguishing fires and preventing their spread.

67. Mechanism of High-Pressure Fine Water Mist Fire Extinguishing: Three-dimensional Movement — Explanation for full or partial extinguishing. During the atomization of high-pressure fine water mist, some droplets with smaller diameters do not travel solely in the direction of the jet. These droplets produce lateral and upward movements within the upper space of the nozzle, allowing the fine water mist to fill the entire space of the protected area. The smaller the droplet size, the more pronounced the lateral transfer phenomenon. This is also referred to as three-dimensional fire extinguishing.

68. Mechanism of extinguishing fires with high-pressure fine water mist: Explanation of its ability to extinguish electrical fires, and why it does not conduct electricity when extinguishing electrical fires: The droplets are small in diameter (10-100 micrometers), and after being released, they are discontinuous and can remain suspended in the air for a long time. It takes a large quantity and a long time to coalesce and condense the mist, making it difficult to form a conductive continuous water flow or surface area on the electrode, and its resistivity is slightly lower than that of air.

69. The open-type fine water mist fire extinguishing system uses water as a medium, employing special atomizing nozzles to break the water flow into tiny droplets under specific pressure (usually 14Mpa) for fire suppression. It is a fixed fire protection system characterized by economy and broad application range, and has become a significant technology replacing Halon fire suppression systems, with a promising application prospect.

70. Composition and Working Principle of High-Pressure Fine Water Mist: The fine water mist fire suppression system consists of a high-pressure fine water mist storage tank, a pump unit for the fine water mist fire suppression device (including a high-pressure main pump, high-pressure backup pump, pressure-regulating pump, pump unit control cabinet, water inlet solenoid valve, water inlet filter, regulating tank, etc.), a water supply system, a water distribution network, a fine water mist fire suppression device zone control valve box set, fine water mist nozzles, high-pressure fine water mist pipes, and a fire detection and alarm system.
