コンプライアンス概要

この概要は現在英語のみで提供しています。

適用範囲

This standard applies to various indoor and outdoor auto tracking and targeting jet suppression systems. It covers systems utilizing UV, IR, image imaging, or thermal imaging components for early fire detection and automatic tracking. It is mandatory for manufacturers of these fire suppression systems to comply with these specifications. This standard replaces the previous version GB 25204-2010.

技術要求

The standard specifies comprehensive performance parameters for suppression devices, categorized by flow rate and jet type (water, foam, or dual-purpose). It defines critical metrics including rated working pressure, protection radius, and targeting time limits under specific operating conditions. Manufacturers must ensure their devices meet the strict structural and rotational angle requirements for effective fire coverage. Environmental and electrical durability requirements are rigorously outlined. The standard mandates testing for high and low temperature resistance, constant damp heat, and insulation resistance. Additionally, it introduces new requirements for electromagnetic compatibility (EMC) and explosion-proof capabilities (referencing GB/T 3836.1 and GB/T 3836.2), ensuring reliable operation in complex industrial environments. For control and detection, the standard requires systems to have at least two types of startup detection components and two types of positioning detection components. Systems must feature dual power supply interfaces with uninterruptible power supply (UPS) support for continuous monitoring and operation. Furthermore, the standard dictates specific video recording durations and centralized/local controller functionalities for seamless fire alarm integration.

試験方法

The standard details rigorous testing procedures to verify compliance. Key tests include performance parameter measurements (flow, pressure, protection radius) and environmental interference tests (ambient light, voltage fluctuation, EMC). It also specifies fire extinguishing performance tests using Class A and Class B fire models according to GB 4351-2023. Systems must undergo continuous reliability testing with multiple ignition triggers to ensure operational stability.

よくある質問
