Alcance y aplicabilidad

This standard applies to the design, manufacture, and testing of fire alarm control units used in industrial and civil buildings. It covers various types of controllers, including independent, regional, centralized, and centralized-regional compatible types. Manufacturers must ensure their fire alarm products comply with these updated mandatory requirements before entering the Chinese market. It does not apply to other fire emergency equipment not classified as control units.

Requisitos técnicos

The standard specifies comprehensive performance criteria for fire alarm control units, detailing requirements for both main components and overall system functionality. It mandates specific configurations for indicators, buttons, and power supplies, including strict regulations on backup power and the prohibition of certain lithium-ion batteries. Controllers must feature an independent operational data storage unit to record system events for fire investigation purposes. Additionally, the standard outlines rigorous electromagnetic compatibility (EMC) and environmental endurance requirements to ensure reliable operation under various interference and climatic conditions. It introduces new communication protocols, specifically the *FECbus protocol*, for seamless integration between controllers and fire electrical control equipment. Compliance with the specified enclosure protection and burning performance for non-metallic materials is also mandatory.

Métodos de ensayo

The standard defines a series of evaluation procedures, including fire alarm function tests, fault alarm tests, and electromagnetic immunity tests such as electrostatic discharge and surge immunity. Environmental tests like low-temperature operation and constant damp heat are also required to verify durability. Furthermore, specific tests for the operational data storage unit and enclosure burning performance are mandated.
