Fire General Requirements for Fire Extinguishing Systems

Fire General Requirements for Fire Extinguishing Systems:

The preparation of this standard complies with the national guidelines for basic construction and the principle of “prevention-oriented, prevention-disinfection combined” fire prevention policy. Based on summarizing the scientific research and engineering application status and lessons learned from the fire extinguishing system in China, it has widely solicited relevant domestic research. Opinions of the departments concerned, design, product production, fire supervision, project construction units, etc., as well as reference to the relevant standard provisions of the United States, Britain, Japan, and other developed countries, were finally reviewed jointly by relevant departments. The fixed fire monitor fire extinguishing system is a group equipment and other critical places for protecting key areas with large area, high fire risk and high value, and can effectively extinguish the fire fighting power of large-scale regional fires in a timely and effective manner. Large fixed fire extinguishing equipment has its special requirements in the design of fire engineering. This specification is divided into six chapters, including general rules, terms and symbols, system selection, system design, system components, and electrical.

1. The design of the power supply for system power equipment shall comply with the provisions of national standards such as "Code for the Fire Protection of Building Design" and "Design Specification for Power Supply and Distribution System".

2. In explosion-proof zones where explosion hazards exist, the selection and installation of electrical equipment and lines, and anti-static measures for pipelines shall comply with the provisions of the current national standard "Design Code for Explosive and Fire Hazardous Electrical Installations".

3. The layout of system electrical equipment shall meet the requirements for safe distance protection of live equipment, and shall comply with relevant national standards and specifications such as "Safety Regulations for Electric Power Industry" and "Safety Guidelines for Electrical Equipment".

4, the system distribution lines should use fire-retardant wire, cable.

5. The cable laying of the system shall comply with the provisions of the National Standards "Low Voltage Distribution Device and Line Design Specification" and "Specifications for Design of Explosive and Fire Hazardous Environment Electrical Installations".

6. The lightning protection design of the system shall be carried out in accordance with the provisions of the current national standards and specifications such as the "Code for the design of lightning protection of buildings".

The above contents are all based on the problems encountered by the trainees during their actual work. For reference, if any questions, please communicate and correct.
