1 Scope

GB 4717-2024 is the Chinese national standard on fire alarm control units, in the field of environment and health protection, safety. It carries no /T suffix, which in the Chinese system means compliance is mandatory: a product or a practice within its scope has to meet it to be lawfully made, sold or carried out in China. It was issued on 29 April 2024 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 May 2025. Classification: ICS 13.220.20, CCS C81. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This document defines the terms and definitions of fire alarm controllers, specifies the classification and nomenclature, requirements, inspection rules and markings, and describes the relevant Appropriate test method: This document applies to the design, manufacture and use of fire alarm controllers (hereinafter referred to as controllers) used in industrial and civil buildings: test:
