Escopo e aplicabilidade

This standard applies to line-type beam smoke fire detectors utilizing the light obscuration principle, with an optical path length of 1m to 100m and a minimum optical path length not exceeding 10m, installed in general industrial and civil buildings. It also covers detectors with thermal disturbance detection functions. Compliance with this standard is mandatory for all manufacturers targeting the Chinese market. It references EN54-12 and BS 5839 for advanced technical alignment.

Requisitos técnicos

The standard mandates general requirements including the presence of a red alarm confirmation light, secure factory settings, and protection against foreign object intrusion. Manufacturers must ensure that auxiliary device connections do not disrupt normal detector operation. For software-controlled detectors, strict documentation and modular design are required to ensure reliability. It specifies critical performance criteria for response thresholds under various conditions. The standard regulates consistency, repeatability, and adaptability to fast and slow obscuration changes. Detectors must maintain stable performance during power parameter fluctuations and optical path length variations. Environmental durability is a core focus, requiring detectors to withstand extreme conditions such as high and low temperatures, constant damp heat, and corrosion. The detector must not issue false alarms during environmental transitions. It also includes stringent electromagnetic compatibility (EMC) requirements, referencing the IEC 61000 series standards for immunity against RF fields, electrostatic discharge, and surges.

Métodos de ensaio

The standard outlines a comprehensive testing protocol, including Consistency Tests to verify response threshold distribution, Thermal Interference Tests for heat disturbance adaptability, and Fire Sensitivity Tests using four types of test fires as specified in GB 4715. It also mandates Environmental Light Interference Tests using tungsten and fluorescent lamps to ensure optical stability.
