GB 16806-1997 General technical requirements for fire linkage control equipment
Some standard content:
GB16806--1997
Fire linkage control equipment is the control center of fire protection equipment in buildings. It is widely used in centralized fire automatic alarm systems and control center fire automatic alarm systems. However, there is no unified technical standard for fire linkage control equipment in my country. Manufacturers often design and produce products according to user requirements and enterprise standards, resulting in different product performance and quality, which brings great difficulties to product quality supervision and inspection, and is not convenient for engineering application, and it is difficult to ensure the reliability of product quality and performance. For this reason, this standard is formulated to provide a technical basis for the production, inspection and quality supervision of such products. This standard includes six parts: scope, reference standards, product classification, technical requirements, test methods and markings. This standard is formed by referring to the national standard GB4717-93 "General Technical Conditions for Fire Alarm Controllers". This standard is a mandatory standard and will be implemented from December 1, 1997. This standard is proposed by the Ministry of Public Security of the People's Republic of China. This standard is under the jurisdiction of the Sixth Technical Committee of the National Fire Standardization Technical Committee. This standard is drafted by the Shenyang Fire Science Research Institute of the Ministry of Public Security. The main drafters of this standard are Song Xiwei, Zhao Yingran, Du Wenli and Sun Lingyun. 485
