Escopo e aplicabilidade

This standard is mandatory for the design, manufacturing, and testing of manual fire call points used in industrial and civil buildings. It applies to both indoor and outdoor types, including explosion-proof variants. Manufacturers of fire alarm trigger devices must comply with these specifications to enter the Chinese market. It does not apply to automatic fire detectors or other fire alarm system components.

Requisitos técnicos

The standard specifies comprehensive requirements for manual fire call points, covering structural integrity, operational reliability, and environmental resilience. Key areas include general appearance and dimensional constraints for the front and operating panels, ensuring clear visual identification and safe manual operation without injury. The standard mandates specific color schemes (red for the front panel, white for the operating panel) and standardized graphic symbols. It defines critical functional requirements, such as the alarm function, which must trigger a fire alarm signal within 5 seconds of activation. It also details the recovery and reset mechanisms for both resettable and non-resettable frangible elements. Devices must maintain normal operation under specified power parameter fluctuations. Furthermore, the standard outlines stringent environmental tolerance requirements. This includes performance under extreme climate conditions (high/low temperature, humidity), mechanical stress (impact, collision, vibration), and electromagnetic compatibility (EMC). Specific IP ratings are mandated based on the application environment, ranging from IP30 for indoor standard types to IP65 for outdoor explosion-proof types. New requirements include resistance to dust pollution, drop impacts, and fluorescent UV lamp aging.

Métodos de ensaio

The standard details a rigorous testing protocol to verify compliance, including non-action and action performance tests using specialized pendulum apparatus. Reliability testing involves 250 repeated action-reset cycles. Environmental tests cover high/low temperature operation, damp heat, SO2 corrosion, and salt spray. Mechanical tests include impact, collision, and sine vibration. EMC tests assess immunity to electrostatic discharge, RF fields, and surges. Additional tests evaluate ingress protection (IP), dust pollution, drop, and UV aging.

Perguntas frequentes

What products are regulated under GB 19880-2024?

GB 19880-2024 regulates manual fire call points (manual fire alarm buttons) used in industrial and civil buildings, including indoor, outdoor, standard, and explosion-proof types.

Are there any updates from the previous version of GB 19880-2005?

Yes, the 2024 version introduces several updates, including new requirements for salt spray testing, IP ratings, dust pollution resistance, drop resistance, and UV aging resistance. It also modifies structural and dimensional requirements and updates EMC testing parameters.

What are the key IP rating requirements under this standard?

The required IP rating depends on the application: IP30 for indoor standard, IP43 for indoor explosion-proof, IP54 for outdoor standard, and IP65 for outdoor explosion-proof manual fire call points.
