    Key Features:

    Chinese/English switchable interface version, allowing customers to intuitively monitor the real-time operating status of the entire system.

    The system provides real-time monitoring of sensors, extinguishing cylinder assemblies, actuation valves, main power supply, and backup power supply, displaying their normal/abnormal status visually.

    The system features real-time temperature monitoring with accurate display; each temperature sensor can be freely configured with two alarm threshold levels.

    The system includes a bypass/disable function — when any abnormality is detected on any input or output port, the system can disable that port to allow temporary normal operation.

    The system can precisely identify and visually display which sensor has triggered a pre-alarm.

    Black box data logging — the system records all anomalies occurring under any condition in real time with full detail.

    Network communication capability — equipped with IP communication functionality, enabling interfacing with fire alarm control panels and PLC systems.

    Application Areas:

    High-end precision equipment, semiconductor manufacturing equipment, data centers, communication base stations, archives, financial centers, and other manned areas housing valuable equipment. It is currently the most widely used clean agent.

    Agent Characteristics

    1. Ideal for manned areas with valuable equipment such as high-end precision instruments, semiconductor facilities, data centers, communication base stations, archives, and financial centers. It is currently the most widely used clean agent.
    2. Mechanism: Physical asphyxiation (vaporization heat absorption, oxygen separation) + Strong chemical inhibition (core: decomposes at high temperatures to release radical scavengers, interrupting chain reactions).
    3. ODP=0, but high GWP (3220). Subject to phase-down under the Kigali Amendment and China's HFCs list.
    4. Relatively safe: Design concentration (7%-9.5%) is below NOAEL, allowing safe evacuation for personnel in the protected zone; however, high-temperature decomposition products (e.g., HF) are irritating and corrosive.
    5. Fast extinguishing speed, effectively suppresses surface and deep-seated fires, with strong anti-reignition capability.
    6. High-temperature decomposition produces HF, which corrodes electronic components and precision metals; ensure discharge time and timely ventilation/cleanup.
    7. Chemically very stable with an extremely long theoretical shelf life (reported as over 50 years).
    8. Cylinder service life is 20-30 years (welded/seamless cylinders).
