LAN system
In the information age on domestic life has important implications, we should follow in the footsteps of the times for the new formation of small local area network to respond to family members surf the Internet, information appliance connected to the network, remote network monitoring needs. At home in the formation of small local area network, you only need to apply for a root Internet broadband lines, so that every room to be able to use the computer at the same time on the Internet. In addition, with the home appliances networking trends, network video Center, network, refrigerators, microwave ovens, network, network video monitoring will continue to occur, these devices can find the nearest network interface connected to the network.
Distribution points: we want to build the LAN is a star topology, any node or connect the cable to fail, will only affect one node, install the access in the information box up the role of master control RJ45 wiring Panel modules, all network socket to line access wiring panel behind information access box should also be equipped with a small network switch through RJ45 patch cord received positive wiring panel interface.
For now go online and after a large number of available network information appliance reserved network information interface, we need each room has at least two network interfaces: one interface can be used as a network, a port can be used as a phone, which is based on the network and phone reuse and line backup requirements. Including RJ45 patch panel, twisted pair, module RJ45 information, I have to select the current epidemic of hyper-v class, you can respond to current and future needs. Cable TV system
Home life may not only in the living room of a TV, bedroom rooms also have television, especially LCD sharp price big screen TV, some families may need to update the TV, the original TV can move to the bedroom. Cable TV system may transmit analog or digital TV signal, the signal sent to each room to watch analog television, you can watch digital TV signal.
Distribution points: home of cable television systems should use better materials, should use a dedicated bi-directional, high shielding, high isolation 1000MHZ coaxial cable and Panel, divider, amplifier (more than four branches need). Allocator should use marked with 5-1000MHz specification of high-quality devices.
Cable should use to outside interference shielding performance of 75-5-, Quad-shielded physical foaming coaxial cable, ensure that each room signal level; cable TV image clear, no Anilox interference. Cable routing is relatively simple, for ordinary commercial houses, we only need family information box to install one of the first four distributor module can be an outside line access cable TV here in the living room and the room. Telephone system
Although it is now very popular mobile phone, but it always used to pursue various preferential-use packages constantly changing calling cards, cell phones may also be lost, this leads to our phone number is not fixed, this problem does not exist, plus its tariff than cell phone low, so the new installation of fixed line telephone or necessary.
A drag-and-now-made four, eight second drag small telephone PABX price very cheap, so home installation small telephone PBX has become possible. Home installation small telephone PBX, you only need to apply for an outside phone line, so every room has a phone. But both internal call, dialed calls, Ray came in roving ring, until someone calls. If not your phone, you can telephone the room number, go to another room. Small telephone PBX in the Villa or duplex room also can be used as a pager to use.
Of course, there are common only information access box set of telephony module Panel, but the Panel can only share access phone calls, phones, ringing, a room with sound, don't listen, there is no room can be kept confidential function call.
Distribution points: telephone system and LAN system wiring in accordance with our "multiplexing and dual backup" requirements with wiring, cable and connector socket materials is the same, the difference is in the information access box of the connection methods. As telephone network twisted pair, we use colour to blue and the blue line on the on the crystals head RJ11. If a small PABX, directly into the PBX interface; if using an ordinary telephone a few modules will first insert telephone RJ11 Crystal modules. Home Theater System
Home theater system is the first choice for modern home entertainment, home theater system is the choice of many families. Home Theater is home to enjoy the cinema identical or similar clear and colorful images, dynamic and as the scene of sound effects. Home theater equipment is divided into two parts of video and audio. The video part is very important in the entire system, usually consisting of large-screen TV or projector, which is required for projector.
AV amplifier is an audio replay of the Centre, its characteristics are multichannel sound playback. Home Theater in a box by five, six, seven, plus a heavy sound. The front left and right sides of the main speakers and reset the speaker can be routed, and rear surround speakers and the rear speakers, and so on should be routed.
Distribution points: home theater system wiring including projector video lines, such as VGA, DVI, chromatic aberration, HDMI and speaker cables. Since it is the top-of-the-home theater systems, these cables are not consecutive, a line to the end, connectors and cables are originally produced and therefore independent of other wiring system, generally only in the living room or den wiring. At design time to accurately calculate the length of the line to buy the appropriate length of cable, to ensure sufficient la place, and audio-visual equipment Center have sufficient allowance.
In wiring, to these expensive cable connector on one end of multilayer plastic carefully PackWell, tie up the rail line, then power-plaster and then to tie up once and traction through PVC casing, Plug one end of the pull, sent, cannot use brute force. In addition, PVC pipe can be selected larger so that they can be smooth, too, will not be stranded in the middle line. AV system
AV is a collection of audio and video, used DVD's you will be aware that signal output includes one channel video, all the way to the left channel, all the way to the right channel. General AV equipment are in the living room, we need the room to appreciate these AV audio-video equipment-play audio through family GCs will the above three lines received in each room. Home AV system, including: DVD AV system, satellite receiver AV system, digital TV, AV system. By AV signal transmission system to the other room DVD, watching satellite TV, watch digital TV program, no need to repeat purchase multiple DVD, satellite receiver, digital set-top boxes and other devices. AV signal can be transmitted to the bedroom, study room, bathroom, kitchen and other rooms.
Distribution points: AV system requires at the same time, three cable, socket panel is a three-hole AV interface, the information in the access box AV module panels, total access audio-visual Centre AV signal, tapping out into the room. From the room by the Group of three cords access AV module panel behind the Group of terminals, the dial through Panel switch implementation on or off.
Because of this wiring circuit through continued, this is the AV system in principle not allowed, but for the sake of sharing and beautiful, the request is not very "fever-" use of the environment, can only fold, so the AV system the most important is the choice of wire rod, we want to select good enough to offset part of the wire. Video cable and audio cable should use a high-purity oxygen-free copper conductor, interface panel and AV module terminals will be 24 k gilt.

Family background music system
Background music gradually become the new darling of the modern home, when we at home doing the housework, when we can rest, we want to be like a hotel like that everywhere hear beautiful, gentle background music. To home from every corner of the diffuse graceful soft background music, this would require in each room, bathroom, kitchen, balcony, etc through family GCS received the audio line. The ordinary family background music system adopts centralized control methods can be entered directly into the sound source can partition control amplifier, you can partition control amplifier is the core of this system. Through the amplifier of audio input selection switch, you can choose from the select multiple sources, all the rooms can only listen to the same program. This system is the most important feature is you can can partition control amplifier individually independent control of each room broadcast need room to play, without the need of a room can be turned off. The system structure is simple, uncomplicated, economical and practical. And each play speaker can separate opening and closing.
Distribution points: family background music system is also a separate wiring system, can come from various room speakers speaker line letter received in the living room a/v Center wall speaker wiring Panel, you can partition control amplifier and then click Add speaker wiring Panel to form a family background music system. Infrared transmitting system
Infrared transmitting system is located in the rooms of the infrared receiver and is located in the living room of the IR emitter. Infrared receiver receives from various audio and video equipment remote control signals into electrical signals to the infrared transmitter, infrared emitter will signal to the same as the original remote control infrared signals, emission control for audio-visual equipment.
Infrared transmitting system wiring is the AV system for supporting projects through which the user can wait in the bedroom or study room on the living room, Department of audiovisual equipment such as DVD player, amplifier, satellite receiver, digital set-top box remote control for comfortable. Thus, by AV distribution system and infrared remote control device to forward system, you can fully enjoy the family information and audio-visual equipment more sharing brings convenience and comfort.
Distribution points: infrared repeater system wiring can not pass information access box, because the individual rooms of the infrared receiver of the signal cable can also join together, and then through a set of signal lines received IR emitter. Room in the infrared receiver installation point is: and the audio-visual equipment in the room on the same side of the wall. The living room of the IR emitter to install the main points are: installation in the living room of audio-visual equipment on the opposite wall. Because the entire system only gives the transmitter power supply, so you should give it an a power switch, so that you can turn off the system when not in use. Monitoring and alarming system
Family residential alarm system consists of a family of intelligent microcomputer alarm host and various front-end detector. Front-end probes can be divided into door sensor, magnetic window, gas detectors, smoke detectors, infrared detectors, emergency button, etc. When it was illegal invasion will trigger corresponding detectors, alarm host will immediately alert signal transmitted to the Community Center, or user-specified phone for security personnel to quickly exhibition; at the Community Center of alarm host will record these information is available. Family residential alarm systems to alert the community security, networking is the best but, if the community has such a system, then the family residential alarm system should be installed.
Distribution points: family residential alarm system can be a part of the comprehensive wiring, micro-computer alarm host can be installed in the external walls of information access box. Various front-end detector-line cabling meeting received information access trunk of protection alert section of meter reading signal acquisition module, then from the module access micro-computer alarm host. Cabling considerations should be
How to according to their own needs to arrange their own wiring?
Modern cabling concept basic hindmost "star topology" structure, this is the last "bus topology" instead. Star topology emphasized that each line is independent, that avoid single points of failure resulting in the paralysis of the whole system. The vast majority of home cabling is using advanced star topology cabling, set to converge to the information in the access box, facilitate centralized management, and facilitate extended the jumper, this is the main contents of the home wiring.
However, we cannot generalize, considers any clothingLines have been summarized information access case management, which also has several system is independent of the route, such as the above mentioned infrared forward system, home theater systems, family background music system does not need to converge to information access box, because of their unique characteristics and needs of independent wiring.

Strong electric with power to pay attention to? (strong or weak to vertical cross)
Home cabling not only cabling, there are strong electric wiring, the strong electricity include: lighting electrical and power. Strong electric on weak and could not have avoided a electromagnetic impact. Therefore, we want to know the following strong electrical and cabling of considerations:
① strong electricity with weak current alignment you want to avoid the next parallel alignment, weak current pipeline and strong electric line parallel alignment needs 50cm distance, if you do not allow this, the available special shielding wire and metal nozzle instead of PVC pipe;
② strong electric, power outlet intervals at least 30 cm;
③ strong electricity and light current alignment cross, at a 90 degree angle crossing;
④ for audio and video quality requirements more stringent AV systems and home theater wiring it is better to use a metal casing, especially the home theater.
