The National Standardization Administration recently issued Announcement No.159, approving the issuance of the mandatory national standard GB 17945-2111 Fire Emergency Lighting and Evacuation Indicating System, which is a revision of GB17945-2111 Fire Emergency Lamps, and the new standard will be implemented on May 1, 2111.

GB 17945-2111 Fire Emergency Lamps has played an active role in guiding the production, use, quality inspection, supervision and management of fire emergency lamps for ten years. However, with the rapid development of modern electronic technology, the performance and product types of products have changed greatly, so the standard needs to be revised urgently. In the process of revision, the compilation team actively adopted international standards and foreign advanced standards, focusing on IEC 61598-2-22 Emergency Lighting Lamps, BS 5266 Emergency Lighting, BS 5499-2 Technical Requirements for Self-luminous Fire Safety Signs and JIS C8115-2-22 Emergency Lighting Safety Requirements. At the same time, according to the implementation of GB 17945－2111 and the domestic status quo, combined with the compilation progress of Technical Specification for Fire Emergency Lighting and Evacuation Indicating System, the content of the standard was revised to the technical requirements of fire emergency lighting and evacuation indicating system, which expanded the coverage of the standard.

The new GB 17945-2111 "Fire Emergency Lighting and Evacuation Indicating System" stipulates the classification, protection level, requirements, test, inspection rules, signs, operating instructions and other contents of the fire emergency lighting and evacuation indicating system. The newly added contents mainly include: dividing the system form and adding corresponding terms and definitions; In terms of technical requirements, the requirements of protection level, self-inspection function, performance of emergency lighting distribution box and performance and structure of emergency lighting distribution device have been added; Revised the requirements for the content of the sign light; The requirements of electromagnetic compatibility are increased, and the appropriate severity level is selected. Approved by the expert meeting, the performance indicators and technical requirements stipulated in this standard are scientific, reasonable and advanced, reaching the advanced level of similar international standards.

the promulgation and implementation of this standard meets the needs of the current industry development of fire emergency lighting and evacuation indication system, and will play an important role in further strengthening product quality supervision and management, promoting the popularization and application of new products and technologies, ensuring people's lives and property safety and realizing international integration.
