Selection of integrated wiring products

1. The importance of product selection

The integrated wiring system is one of the basic infrastructures in intelligent buildings and intelligent communities. From the analysis of previous domestic and foreign projects, the selection of system equipment and materials is the key link and important content of engineering design.

2. Prerequisites for product selection

● The nature, functions and environment of intelligent buildings and intelligent communities, including the level, status and importance of the city where they are located; distinguish whether they are important high-tech intelligent buildings or ordinary office intelligent buildings.

● The construction scale and plan of intelligent buildings and intelligent communities, including the distribution of buildings, the number of floors, floor plan, building area, various pipeline systems, and design and construction progress.

● The recent user information demands of intelligent buildings and intelligent communities, and the estimated development needs and changes in information services, etc.

● The objective environment in which the intelligent building is located, its future development and changes, such as whether there are any sources of electromagnetic interference now and in the future, whether there is the possibility of developing into an intelligent community, etc.

10.1.2 Principles of product selection

(1) It must be combined with engineering practice.

(2) The products selected should comply with my country’s national conditions as well as relevant international, domestic and industry technical standards.

(3) Combine short-term and long-term plans.

(4) Comply with the principle of unifying technological advancement and economic rationality.

10.1.3 Specific steps and working methods for product selection

(1) Understand the prerequisites and collect basic information.

(2) Before selecting a product, you should conduct an investigation or collect product information, visit units that have already used the product, and fully understand its use effect; listen to various feedback in order to analyze the product; carefully select two or three products and prepare for further evaluation and inspection.

(3) Objectively and impartially compare and comprehensively evaluate the technical and economic aspects of the shortlisted products to select the ideal products.

(4) Focus on the technical strength, production equipment, process flow and after-sales service of the manufacturers of the shortlisted products, conduct on-site inspections of product usage, and conduct on-site tests of certain basic performance in order to obtain first-hand information.

(5) After the above work, you should have a relatively comprehensive understanding of the selected products. Based on the principles of economy, practicality, and reliability, you should put forward your opinions on the final selection of products and submit them to the construction unit or relevant decision-making department for confirmation.

(6) Finally, the specifications and quantities of the main equipment, various cables, wiring components and other accessories required for the integrated wiring system project should be calculated and summarized, and the details of the specific product ordering should be negotiated with the manufacturer, especially the product quality, delivery date, location and payment method, etc. These should be clearly stipulated in the order contract to ensure that the integrated wiring system project can proceed smoothly as planned.
