I. Overview

The hanging superfine dry powder fire extinguishing device is composed of a fire extinguishing agent storage container, a super dry powder fire extinguishing agent, a starting component, a pressure display device, a nozzle and other components. Normal startup method:

Temperature control: When the ambient temperature rises to the set nominal value, the valve on the fire extinguishing device automatically opens, releasing ultra-fine dry powder fire extinguishing agent to extinguish the fire. Thermal initiation: In a specific environment, when the fire extinguishing device needs to be quickly activated, the fire signal is quickly transmitted to the fire extinguishing device via the thermal line to release the ultra-fine dry powder fire extinguishing agent to extinguish the fire. Linkage.

Electric control: It can be linked with the fire alarm controller, receive the fire alarm controller instructions, and release the superfine dry powder fire extinguishing agent to extinguish the fire.

Product application range:

1. Extinguishing live equipment fires: fires in live equipment such as machine rooms, substations, cable tunnels, cable trenches, generator rooms, high and low voltage distribution rooms, urban comprehensive underground pipe corridors, and electric vehicle charging piles.

2. Extinguish solid fires: such as cotton, wood, linen, paper, rubber, plastic, tobacco and other combustible solid fires. For example: wood processing production workshops and warehouses, furniture exhibition halls and warehouses, clothing and hat production workshops and warehouses, various archives, data rooms, printing, papermaking, tobacco production and warehouses, and so on.

3. Extinguish liquid fires: such as crude oil, heavy oil, diesel, gasoline, petrol and gasoline dispensers at gas stations, organic solvents and other combustible liquids and soluble solids. For example: diesel generator room, paint spraying workshop, fuel oil boiler, flammable liquid storage warehouse, plastic paraffin and so on.

4. Extinguish flammable gas fires: fires that can cut off gas sources such as coal gas, natural gas, acetylene, etc.

Fourth, matters needing attention

1. During the storage, transportation and installation of fire extinguishing equipment, collision is strictly prohibited. Do not use external force on the sprinkler or glass ball, and do not loosen any part of the fire extinguishing device.

2. Before installation, check that the pressure indicator pointer is in the green area.

3. The lifting ring or bracket should be installed firmly to avoid shaking when the fire extinguishing device is sprayed.

4. Fire extinguishing equipment should not be installed near heat sources, rain and vibration.

5. The installation area of fire extinguishing equipment should be provided with ventilation and ventilation facilities. When the fire extinguishing agent is released, personnel should immediately evacuate the site and enter the site for cleaning after exhausting dry powder.

6. Maintenance and refilling of fire extinguishing equipment should be carried out by a professional manufacturer approved by the public security fire supervision department. Or contact your local dealer or manufacturer.

7. Please read the product manual carefully before and after installation.
