適用範囲

This standard applies to electrical fire monitoring equipment used within electrical fire monitoring systems in China. It is mandatory for manufacturers of monitoring devices that receive signals from detectors measuring residual current, temperature, and other electrical fire hazard parameters. This standard is mandatory for all manufacturers of electrical fire monitoring equipment entering the Chinese market. It does not apply to the detectors themselves, which are covered by other parts of the GB 14287 series, such as GB 14287.2 and GB 14287.3.

技術要求

The standard specifies comprehensive requirements for the monitoring equipment, focusing on its ability to receive, process, and display alarm signals. Key areas include monitoring alarm functions, where the equipment must issue audible and visual alarms within 10 seconds of receiving a signal and display real-time residual current and temperature values with a display error not exceeding 5%. It also mandates strict fault alarm functions, requiring the system to identify and signal faults like disconnections or short circuits within 100 seconds. The equipment must feature a self-check function and an information display and query function to manage alarm and fault logs effectively. Furthermore, the standard outlines requirements for power supply functionality, ensuring stable operation under voltage fluctuations (AC187V to AC242V) and specific load conditions. Manufacturers must ensure the equipment has at least two levels of operation access control. Other critical parameters cover insulation resistance, leakage current, and dielectric strength to ensure electrical safety.

試験方法

The standard details a rigorous testing protocol to verify compliance. This includes monitoring and fault alarm function tests to check response times and signal accuracy. Environmental and mechanical robustness are evaluated through low temperature (operation) tests, constant damp heat tests, vibration (sine) tests, and collision tests. Electromagnetic compatibility is heavily emphasized, requiring tests such as radiated electromagnetic field immunity, conducted disturbance immunity, electrostatic discharge immunity, and surge immunity tests in accordance with the GB/T 17626 series. Additionally, electrical strength tests and leakage current tests are mandated to verify electrical safety parameters.

よくある質問

What products are regulated under GB 14287.1-2014?

GB 14287.1-2014 regulates electrical fire monitoring equipment, which is the central control unit that receives alarm signals from electrical fire monitoring detectors and issues alerts. It does not cover the detectors themselves.

Are there any updates from the previous version of GB 14287.1?

Yes, compared to the 2005 version, the 2014 update introduces requirements for receiving and displaying residual current and temperature values, adds an information display and query function, and includes several new electromagnetic compatibility (EMC) tests such as radiated and conducted immunity tests.

What are the key electromagnetic compatibility (EMC) testing requirements?

The equipment must pass various EMC tests including electrostatic discharge, radiated electromagnetic field, conducted disturbance, electrical fast transient, and surge immunity tests. These tests are based on the GB/T 17626 series standards.
