Generally, the comprehensive wiring system of the building involves six subsystems, and the residential wiring system usually includes the following three parts, working areas; horizontal areas; management areas. In addition, for multi -storey houses or buildings, the system also includes the wiring of the building and the trunk wiring part of the community.

The residential work area is mainly composed of panels and socket modules. The sockets installed in each family room can be selected with different types of modules, such as 5 types of modules, TV modules, optical fiber modules, video and audio modules, etc. In addition, different types of panels can be selected according to the requirements, such as British, American, 86, single -mouth, double -mouth, three, four -port panels, etc.

The residential level area is mainly composed of various cables. According to the 570A standard, different applications use different wiring media. The cables for the voice system use 3 or 5 non -shielded twisted twisted twisted pair (UTP) that meet the ANSI TIA/EIA standards, but it is recommended to use 5 types of cables.

For transmission data, 5 types of UTPs that meet ANSI TIA/EIA-586A standards are used. For the situation where the communication bandwidth or anti -interference requirements are high, the optical cable can be used as the transmission medium. The transmission of the video signal adopts a 75Ω coaxial cable that meets SCTE EPS-SP-001. The coaxial cable can meet the user's requirements for broadband because it does not require expensive adaptors, and can also save users' investment.

The management area is composed of different series of installation modules. It is the center of the system. It is equipped with high -speed and high -quality wiring modules and cable jumps. It can provide voice, data, security precautions, images and videos for different families Applications. All services are implemented by the communication sockets/panels connected to each room, while the centralized indoor/outdoor voice, data, and image signals are brought together. , TV, etc.

Family wiring center (wiring box) is generally installed in every family. The installation location can be changed according to the planning of the entire residential community and the access path of the external line. Users can choose different specifications of wiring boxes and equipped with different functional modules according to the types and needs of the residents.

The main components that are available in the center of the wiring center are:

(1) Module board: telephone module board, 5 type of module board, 110 wiring frame, video distribution, monitoring alarm module, etc.

(2) Jump line: 5 types of jumper, video coaxial jumper;

(3) Equipment: Ethernet, video amplifier.

For multi -storey houses or buildings, in addition to the working area, horizontal area, and management area of the residential unit wiring system, the wiring of each home unit needs to be connected to the trunk area of the building management center and the supervisor of the entire building wiring system. district.

The wiring of the building adopts a star -type topology, and the medium used includes UTP and 75Ω coaxial cables. The level of its wiring depends on the specific situation. No matter which level of solutions to be used, a multimedia wiring system wiring box needs to be set up in a residential resident. Connect with the main line rack of the community. According to different communities, you can choose 1-2 5 types of non-shielded twisted twisted lines and 1-2 75Ω coaxial cables. The selected trunk wiring scheme is set to a intermediate wiring box for each staircase unit or a building.
