Cabinet-Type IG100 Fire Suppression System – Frequently Asked Questions

Q: What types of facilities are suitable for cabinet-type IG100 fire suppression systems?

A: Suitable for enclosed protected areas such as small computer rooms, distribution rooms, archives, and precision equipment rooms; it can extinguish Class A, B, and C fires, as well as energized electrical fires.

Q: What is the cabinet-type IG100 fire suppressant?

A: IG100 fire suppressant is high-purity nitrogen with a purity of 99.9% or higher. It is an inert, clean gas that is environmentally friendly, leaves no residue, and does not deplete the ozone layer.

Q: What are the activation methods for a cabinet-type IG100 fire suppression system?

A: It features three activation modes—automatic, manual, and mechanical emergency—and can be connected to a fire alarm control panel to initiate spray discharge via interlock with smoke and heat detectors.

Q: What is the difference between the cabinet-type IG100 system and the pipework-based IG100 system?

A: Cabinet-type systems are prefabricated, integrated units in which the cylinder assemblies are housed within the cabinet, eliminating the need for a separate cylinder room. They are easy to install and well-suited for small to medium-sized protected areas.

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

A: The cabinet shall be installed within the protected area or in an adjacent location, with an unobstructed spray path. The protected area shall be equipped with automatic pressure relief vents in accordance with relevant standards to ensure the piping system remains tightly sealed.

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

A: Regularly check the pressure gauge readings on the cylinders, inspect cylinder valves and pipeline fittings for leaks, test the alarm‑interlock devices, and examine the cabinet and cylinder bodies for rust or deformation.

Q: What effects does the discharge of IG‑100 gas have on personnel within the protected area?  

A: Prior to discharge, an audible and visual alarm will be activated, and personnel must evacuate promptly. After discharge, the oxygen concentration in the space will decrease; entry into the protected area is permitted only after thorough ventilation.

Q: Will IG100 damage precision electronic equipment?

A: High-purity nitrogen is non-corrosive, dust-free, and non-conductive; after discharge, it leaves no residue and will not damage servers, precision instruments, or other electronic equipment.

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 high‑purity nitrogen.

Q: Does the cabinet-type IG100 fire suppression system meet the acceptance requirements for fire protection projects?

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