2. Commonly used materials generally include: pipes, steel, wire troughs, cables, metal hoses, special-shaped plastic pipes, wires, flame-retardant plastic pipes, junction boxes, pipe clamps, roots, steel wires, lead wires, expansion plugs, solder, batteries, saw blades, straps, expansion bolts, markers, etc.
3. For the installation steps of fire alarm system installation, we should first be familiar with the electrical system drawings, and at the same time we should be familiar with structural drawings, architectural drawings, decoration drawings and other related professional drawings. After familiarizing ourselves with the drawings in detail, we will review the drawings based on our daily work experience, and organize technical briefings to check the design and construction issues, and finally handle various technical changes negotiation materials, and at the same time determine the construction methods and equip other relevant materials or temporary facilities for production such as corresponding labor, equipment, materials, machinery, etc.
