Compliance-Überblick

Dieser Überblick ist derzeit nur auf Englisch verfügbar.

Geltungsbereich und Anwendbarkeit

This standard applies to auto tracking and targeting jet suppression systems that use water or foam mixture as the extinguishing medium. It covers systems utilizing infrared, digital image, or other fire detection components for early fire location and automatic control. It is mandatory for manufacturers producing these fixed fire suppression systems for the Chinese market. The standard categorizes systems into auto fire monitor devices (flow rate >16L/s) and auto jet devices (flow rate ≤16L/s), further classified by jet type (spray or sprinkler).

Technische Anforderungen

GB 25204-2010 specifies comprehensive performance requirements for auto tracking and targeting jet suppression systems. Chapter 5 is mandatory, covering structural integrity, horizontal rotation angles (minimum 180°), and pitch angles. The standard defines critical performance parameters including rated flow, working pressure, jet radius, and maximum protection radius, which must align with the manufacturer's declared values. Environmental resilience is a core focus. The system must withstand high and low temperature tests (referencing GB/T 2423.1 and GB/T 2423.2), constant damp heat, and vibration tests without false activation or structural damage. Electrical safety requirements mandate an insulation resistance greater than 20MΩ and the ability to withstand a dielectric strength test of 1500V for 1 minute. The standard also sets strict criteria for automatic control functions, requiring intelligent detection, linkage decision management, and automatic communication with fire alarm systems. Systems must include dual power supplies with automatic switching, featuring an uninterruptible power supply (UPS) providing at least 8 hours of monitoring time and 1 hour of operational time. Additionally, a 24-hour on-site video recording capability is required.

Prüfverfahren

Testing procedures evaluate the system's physical and operational limits. Key tests include flow and pressure measurements to determine jet and protection radii, targeting time evaluation using standardized test fires, and environmental interference tests (e.g., ambient light interference). Fire suppression efficacy is tested against a 1A fire class model, requiring extinguishment within 3 to 6 minutes. Reliability is verified through 10 consecutive ignition trigger tests, referencing GB 4351.1-2005 for fire test models.

Häufige Fragen

What products are regulated under GB 25204-2010?

It regulates auto tracking and targeting jet suppression systems, including both auto fire monitor devices and auto jet devices that use water or foam mixtures for automatic fire suppression.

Is Chapter 5 of GB 25204-2010 mandatory?

Yes, Chapter 5, which covers all performance requirements, is mandatory, while the rest of the standard is recommended.

What are the power supply requirements under this standard?

The system must have at least two power supply interfaces with automatic or manual switching. One must be an uninterruptible power supply (UPS) lasting at least 8 hours in monitoring mode and 1 hour in working mode.
