Alcance y aplicabilidad

This standard applies to fire indicating panels (火灾显示盘) installed and used in general industrial and civil buildings. It is mandatory for all manufacturers producing fire alarm display equipment for the Chinese market. For environments with special performance requirements, other relevant standards shall apply, though this standard may be used as a reference.

Requisitos técnicos

The standard outlines stringent requirements for basic functions, including fire alarm display, fault display, and supervisory alarm display. The panel must issue audible and visual signals within 3 seconds of receiving an alarm. It also mandates a clear hierarchy of information display, prioritizing fire alarms over faults, and requires all text and indicators to be in Chinese. Regarding power supply and components, the panel can use a 220V AC main supply or a DC power source (preferably 24V). If AC powered, it must have a backup battery with automatic switchover capabilities. The standard also sets specific visibility and audibility criteria for indicators and sounders, requiring them to be clearly perceptible from defined distances and angles. For electrical safety and EMC, the panel must meet minimum insulation resistance and withstand electrical strength tests. It also defines strict electromagnetic compatibility (EMC) thresholds to ensure the device resists radio frequency interference, electrostatic discharge, and voltage surges. Finally, the standard specifies environmental endurance limits. The equipment must reliably operate under extreme climate and mechanical conditions without functional degradation. This includes tolerance to low temperatures, constant damp heat, and sinusoidal vibrations.

Métodos de ensayo

The standard mandates a series of rigorous tests to verify compliance. Key testing procedures include the Basic Function Test (evaluating alarm response time and display logic), Insulation Resistance and Electrical Strength Tests, and a comprehensive suite of EMC Tests (such as electrostatic discharge and surge immunity based on GB/T 17626 series). Furthermore, Environmental Endurance Tests are conducted to simulate harsh conditions, including low temperature (operational), constant damp heat, and vibration (sinusoidal) tests, largely following the methodologies outlined in GB 16838.

Preguntas frecuentes

What products are regulated under GB 17429-2011?

It applies to fire indicating panels installed in general industrial and civil buildings. Panels with special performance requirements for other environments should also refer to this standard unless otherwise specified by relevant standards.

Are there any updates from the previous version of GB 17429?

The 2011 version replaces GB 17429-1998. It refines basic function tests, adds new tests such as leakage current, surge immunity, and vibration endurance, and introduces requirements for user manuals and inspection rules.

How does GB 17429-2011 differ from ISO standards?

The standard incorporates electromagnetic compatibility and environmental endurance tests that align with international IEC standards, such as GB/T 17626.2 for ESD and GB/T 17626.4 for electrical fast transients, adapting them specifically for Chinese fire alarm systems.
