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 the design, manufacturing, and inspection of audible and/or visual fire alarm signaling appliances used in industrial and civil buildings. It covers various types of alarms, including audible fire alarms, visual fire alarms, audible and visual fire alarms, and fire information alarms. It is mandatory for all manufacturers producing fire alarm signaling devices for the Chinese market. The standard categorizes these devices by usage location (indoor or outdoor) and installation method (wall-mounted or ceiling-mounted).

技術要求

The standard specifies comprehensive requirements for the performance and reliability of fire alarm signaling appliances. Key areas include basic functionality, where the device must respond to control signals within 3 seconds and report faults within 100 seconds. It also defines alarm signal consistency, setting limits on the variation of sound pressure levels and effective luminous intensity among multiple units. Additionally, the standard outlines power performance criteria, ensuring devices operate correctly under voltage fluctuations and specifying battery capacity requirements for sustained operation. Manufacturers must ensure devices meet strict electromagnetic compatibility (EMC) and environmental tolerance requirements, including resistance to electrostatic discharge, temperature extremes, humidity, and mechanical vibrations. The standard also introduces new requirements for signal synchronization functionality and shell flame retardancy for non-metallic enclosures. Detailed parameters for sound pressure levels, flash frequencies, and luminous intensity across different angles are specified to ensure effective alerting.

試験方法

The standard details rigorous testing procedures to verify compliance. Key tests include the basic function test, alarm signal consistency test, and alarm signal performance test (measuring sound pressure and luminous intensity at various angles as per Appendix A and Appendix B). Environmental and durability tests are conducted according to GB/T 16838, including high/low temperature operation, damp heat cycling, and sulfur dioxide corrosion. Electromagnetic compatibility is assessed through tests for electrostatic discharge, radiated immunity, and electrical fast transients. Mechanical robustness is verified via vibration, shock, and collision tests. Additionally, shell protection grade (IP rating) and needle flame tests are mandated to ensure physical safety and durability.

よくある質問

What products are regulated under GB 26851-2026?

GB 26851-2026 regulates audible and/or visual fire alarm signaling appliances used in industrial and civil buildings, including dedicated audible alarms, visual alarms, combined audible/visual alarms, and fire information display alarms.

Are there any updates from the previous version of GB 26851?

Yes, the 2026 version replaces GB 26851-2011. Key updates include the addition of fire information alarms, new requirements for signal synchronization, shell flame retardancy, and collision tests, as well as revised environmental and EMC testing conditions.

What are the installation categories defined in GB 26851-2026?

The standard classifies alarms by installation method into wall-mounted and ceiling-mounted types, and by usage location into indoor and outdoor types, each with specific performance and protection requirements.
