FAQ for Cabinet-Type Carbon Dioxide Fire Suppression Systems

Q: What types of facilities are suitable for cabinet-type carbon dioxide fire suppression systems?

A: Suitable for enclosed protected areas such as distribution rooms, small computer rooms, oil-immersed equipment rooms, and cultural relic storage facilities; it can extinguish Class A, B, and C fires as well as energized electrical fires, but is not suitable for fires involving reactive metals.

Q: What is the extinguishing principle of a cabinet-type carbon dioxide fire suppression system?  

A: After liquid carbon dioxide is discharged, it rapidly vaporizes, thereby cooling the burning material while simultaneously diluting the oxygen concentration in the surrounding space, extinguishing the fire through both cooling and asphyxiation.

Q: What are the activation methods for cabinet-type carbon dioxide systems?

A: Supports three activation modes—automatic, manual, and mechanical emergency—and can be connected to a fire alarm control panel, with spray discharge triggered by interlocked operation of smoke and heat detectors.

Q: What is the difference between a cabinet-type carbon dioxide system and a piped high-pressure carbon dioxide system?  

A: The cabinet-type system is a prefabricated, turnkey unit in which cylinders and valves are integrated within the cabinet, eliminating the need for a separate cylinder room. It is easy to install and well suited for protected areas with limited floor space.

Q: What are the key considerations during system installation and construction?  

A: The cabinet shall be installed within or adjacent to the protected area, ensuring an unobstructed spray path; nozzles shall be properly arranged, pressure relief vents shall be provided in accordance with relevant standards, and piping shall be tightly sealed.

Q: What items should be checked during routine inspections and maintenance?

A: Regularly weigh cylinders to verify the remaining agent quantity, inspect the cabinet, cylinder valves, and pipeline fittings for leaks, test the alarm‑interlock functionality, and check the cabinet for rust or damage.

Q: What effects does carbon dioxide discharge have on personnel within the protected area?

A: Carbon dioxide poses risks of asphyxiation and frostbite; upon receiving an audible and visual alarm, personnel must evacuate immediately. After the discharge is complete, ensure adequate ventilation, and only enter once safety has been confirmed.

Q: Will the release of carbon dioxide damage precision electronic equipment?

A: The agent leaves no residue and vaporizes rapidly; however, it causes a sharp temperature drop at the moment of discharge, and in humid environments, condensation may form. When selecting this product for precision electronic applications, it is essential to assess the ambient humidity.

Q: Can the agent be refilled on-site after it has been discharged?

A: On-site refilling is not permitted. After discharge, the cylinders must be transported back to a qualified fire‑safety organization for inspection and subsequent recharging with carbon dioxide extinguishing agent.

Q: Does a cabinet-type carbon dioxide fire suppression system meet the acceptance requirements for fire protection projects?

A: The product is accompanied by a fire‑safety inspection report and complies with relevant gas‑extinguishing standards. Upon completion of installation and commissioning, it can be integrated with the protected area to facilitate overall fire‑safety acceptance.
