Installation technology between integrated wiring work area and telecommunication

(1) Working area

1 The work area of the communication leads (also known as information outlets) installation process, it is appropriate to meet the following provisions.

① installed on the ground of the information outlet junction box should be waterproof and compressive performance.

② installed on the wall or pillar of the information outlet bottom box, multi-user information outlet box and assembly point wiring box at the bottom, their lower edge from the ground height should be 30Omm; If the room is equipped with movable floor, the above height must be guaranteed, be sure to increase the installation height of the active floor.

2 The Power configuration and installation process of the working area shall conform to the following regulations.

① Each workspace should be configured with at least 1 220V AC power outlets and should be installed in a convenient location.

② work area of the power outlet should be used with protective grounding single-phase power sockets, protection grounding and 0 line should be strictly separated.

(2) Telecommunication room

Telecommunications between the handover or wiring between, etc. it refers mainly to the installation of integrated cabling system floor wiring equipment (FD) and computer systems floor network Equipment hub (hub) or switch (SW) sites, and according to the site can be set up cable shaft, equipotential grounding, power sockets, UPS distribution boxes and other facilities. When the above venues are relatively well-off, allows the integrated wiring system and the weak current system equipment (such as building security, fire, building equipment monitoring system, wireless signal coverage systems, such as cable slots and the installation of functional modules) in the same place from the point of view of the building, the telecommunications between the switch can be called weak electricity between, It is relative to the power line of the strong electricity between the distinction.

1 The number of telecommunication should be determined according to the floor range and working area of the service. If the number of information points in the floor is not greater than 400,-horizontal cable length not exceeding 90m it is advisable to set up a telecommunication room; two or more telecommunication rooms should be installed when exceeding this range; If the number of information points per floor is small and the horizontal cable length is less than 90m, it is better to set up a telecommunication room for the children's floors. In order to save room area and reduce the number of equipment.

2 telecommunication should be set up separately from strong electricity to ensure the safe operation of Communication (information) network, the cable shaft (sometimes called cable shaft and weak shaft) should be set up in the telecommunication room or its immediate vicinity.

3 The area of telecommunications between the area should not be less than 5m2, can also be in accordance with the actual installation of the wiring equipment and network set up the capacity of the appropriate adjustment, that is, increase or reduce the space between telecommunications.

The above telecommunications between the use area of the calculation basis: In general, the integrated wiring system and computer network equipment with 19-inch standard rack (cabinet) installation. Rack (cabinet) size is usually (mm) wide x900 (mm) deep x2000 (mm) high, a total of 42U installation of the machine disk space. In the rack (cabinet) can be installed fiber optic connectors, RJ45 (24-port) wiring module, multi-line adapter module (100 pairs), line frame, computer system hub (hub) switch (SW) equipment. If the above equipment is configured according to the 200-per-storey telephone and data points of each building, approximately 2 19-inch (42U) rack (enclosure) space is required to calculate the minimum area of 5m2 (2.5mx2.0m) between telecommunications. such as in the telecommunications room at the same time set up the intranet, external network or private network, considering their network structure complex, network size expansion, increased number of equipment and ease of maintenance and management factors, 19-inch racks (cabinets) should be set up, and in the case of maintaining a certain spacing, forecasting and estimating the area between telecommunications.

4 Telecommunications equipment installation and power requirements should be referred to the standards of the equipment between the provisions of the process, see the following parts of the equipment.

5 The telecommunications should be used to open outside the C-class fire door, the door is wide than 0.7m. The temperature and humidity between telecommunications are based on the requirements of wiring equipment, the internal temperature of telecommunications should be 10℃~35℃, relative humidity should be 20% 80%. If a Computer information network device (such as a hub or a switch) is installed in a rack (cabinet), its environmental conditions shall meet the requirements of the equipment. temperature, humidity assurance measures by the air-conditioning professional responsible for the consideration of the solution.

The requirements for the installation process are based on the general wiring racks and other equipment required by the environmental requirements, due consideration is given to the installation of a small number of computer systems and other network equipment. If with the user program-controlled switchboard, computer network system and other equipment together, the telecommunications or equipment between the installation process requirements should be implemented in the relevant standards of the provisions.
