III. Overall Configuration of the Core System (Core Business: Primarily Gas Fire Suppression Systems, with Comprehensive System Integration)

The Xinlin Fire Protection Integrated Solution takes its self-developed and manufactured gaseous fire suppression system as its core feature, seamlessly integrating with a full suite of conventional fire protection systems to create a closed-loop fire safety framework that delivers “precise extinguishing in high‑risk spaces, foundational security across all building areas, and coordinated, system‑wide prevention and control.” This approach not only addresses the specialized need for residue‑free, zero‑damage fire suppression in precision‑critical, enclosed, and high‑hazard environments but also ensures compliance with comprehensive fire safety requirements for the entire building.

1. Core Business: Intelligent Gas Fire Suppression Systems (a specialized, competitive system)

As the company’s core flagship product and a key pillar of its competitive edge, Xinlin boasts end-to-end capabilities spanning the full lifecycle—research and development, manufacturing, installation, and operation & maintenance—of its comprehensive range of gas‑based fire suppression systems. These systems are distinguished by their zero‑residue, non‑polluting nature, superior electrical insulation, high extinguishing efficiency, and compatibility with precision equipment. They are ideally suited for high‑risk, sensitive, and enclosed environments where water‑based sprinkler systems fall short, effectively preventing water‑damage to equipment and dust‑induced contamination. As such, they represent the preferred security solution for data centers, electrical distribution facilities, archives, cleanrooms, and other critical spaces. All products comply with relevant standards and regulations, and we offer customized configuration options and turnkey project implementation. Our core product segments include:

● Heptafluoropropane gas fire suppression system: The mainstream high-efficiency, clean‑agent fire suppression system delivers rapid extinguishing, operates at low storage pressure, and offers superior safety and stability. It is human‑friendly, causes no equipment corrosion, and leaves no residue after activation. Designed for enclosed spaces housing manned, high‑value, precision equipment, it is the most widely deployed specialized fire suppression solution across government, enterprise, commercial, and industrial applications.

● IG541 Gas Fire Suppression System: A purely natural, environmentally friendly extinguishing agent composed of nitrogen, argon, and carbon dioxide. It is non‑toxic, non‑polluting, ozone‑depleting‑free, and rapidly dissipates after fire suppression, making it ideally suited for high‑standard, eco‑friendly protection applications such as archives, cultural relic storage facilities, cleanrooms, and premium data centers.

● IG100 Nitrogen Fire Suppression System: Using high-purity nitrogen as the extinguishing medium, it is 100% natural, zero‑pollution, leaves no residue, and is non‑corrosive. It does not harm the atmospheric environment and is safe, non‑toxic, and suitable for direct use in occupied spaces. Its fire‑extinguishing principle relies on rapidly reducing the oxygen concentration within the protected area, achieving precise smothering without generating any harmful decomposition products. It exhibits excellent resistance to both high and low temperatures and exceptional stability, making it ideal for ultra‑high‑environmental‑protection, high‑safety‑grade, and demanding operational environments such as new‑energy storage power stations, nuclear‑power‑related equipment rooms, cutting‑edge precision laboratories, high‑purity process cleanrooms, and advanced data centers.

● Perfluorohexanone fire suppression system: A next-generation, safe, environmentally friendly, and clean fire‑extinguishing agent that is stored in liquid form at ambient temperature, operates at low pressure, exhibits extremely low toxicity, has an ODP of zero, and a very low GWP—its environmental performance far surpasses that of conventional gaseous fire‑suppression systems. It delivers rapid extinguishing with excellent heat‑absorption and cooling effects, leaves no residue after use, does not corrode equipment, and is non‑conductive. It is ideally suited for applications involving long‑term human presence, ultra‑high‑precision equipment, and high‑end clean environments, and is widely deployed in demanding protection settings such as advanced laboratories, energy‑storage facilities, precision‑instrument workshops, data centers, and medical‑equipment rooms—making it the preferred solution for cutting‑edge green fire protection today.

● Carbon dioxide gas fire suppression system: It features low extinguishing costs and broad applicability, offering both total flooding and localized application modes. Primarily suited for unattended environments such as distribution rooms, oil storage areas, and high‑risk industrial equipment zones, it swiftly prevents fire spread.

The entire series of gas fire suppression systems can be integrated with the fire alarm control panel to enable automatic detection, delayed warning, intelligent start‑stop control, and precise zoned extinguishing. They support both single‑zone and multi‑zone coordinated operation, and can be customized to meet diverse space sizes and protection‑level requirements.

2. Automatic Fire Alarm and Interlock Control System

As the central control hub of the entire fire protection system, it is equipped with smart smoke and heat detectors, manual call points, audible‑visual alarms, and a fire‑alarm control panel, enabling 24/7 real‑time monitoring of fire conditions across all areas. It can be seamlessly integrated with our company’s gas‑extinguishing systems, smoke‑extraction and pressurization systems, emergency public‑address systems, and other devices. Upon detection of a fire, it initiates precise zone‑specific alerts and activates the corresponding fire‑suppression equipment, facilitating coordinated operations that provide targeted extinguishing in high‑risk spaces and comprehensive protection throughout public areas.

3. Automatic Sprinkler Fire Suppression System (for Common Areas)

For public and open areas such as shopping malls, corridors, garages, and office spaces, we provide well‑established wet‑pipe and dry‑pipe sprinkler systems, ensuring compliant installation of piping networks, equipment, and water‑pressure testing. This guarantees rapid initial suppression of fires in these open spaces, complementing gas‑based fire‑extinguishing systems to create a synergistic protection strategy that combines targeted specialized safeguards with comprehensive baseline coverage.

4. Fire Water Supply and Fire Hydrant System

The system is equipped with a complete set of facilities, including outdoor pipeline networks, a fire water tank, a pump house, indoor and outdoor fire hydrants, and pressure‑stabilizing equipment. By implementing a scientifically designed zoning water supply scheme, it ensures stable and adequate fire‑fighting water delivery throughout the building, meets the project’s basic fire‑safety acceptance criteria, and provides a solid foundation for overall fire safety.

5. Smoke Control and Ventilation Systems

Positive-pressure ventilation and mechanical smoke-extraction systems are installed in areas such as stairwells, basements, atria, and equipment rooms. In the event of a fire, these systems rapidly exhaust toxic smoke, ensuring unobstructed evacuation routes and providing a safe environment for personnel evacuation, equipment firefighting, and emergency rescue operations, thereby meeting the full‑range requirements of evacuation and protection.

6. Emergency Lighting and Intelligent Evacuation System

Equipped with intelligent emergency lighting, dynamic evacuation signage, and an emergency broadcasting system, it can automatically adjust evacuation routes based on the fire’s location, deliver real-time evacuation instructions, and guide occupants to evacuate quickly and in an orderly manner, making it well-suited to the safety‑protection needs of high‑occupancy venues and industrial facilities.

 

IV. Core Scenario Customization Plan
