VII. infrared forwarding system (optional)


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 to put the 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.

VIII. monitoring alarm system (optional)


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 '; 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.




9. important notes for cabling


◇ How 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, and that any wiring is information access box, the summary administration also has several independent wiring system is, as the above mentioned infrared forward system, home theater systems, family background music system does not need to converge to information access box, as Scott Sudoku features 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 to power the 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 and weak current alignment cross, at a 90 degree angle crossing.
4, for audio-visual quality requirements more stringent AV systems and home theater wiring it is better to use a metal casing, especially the home theater.

10. Summary


This article describes family excelent arrangements which are required, which is drawn and which are optional. We are in the "meet now, right ahead" principle, in the new house renovation project in financial resources to permit the greatest possible number of select suits their needs several routing system. In addition, this article also highlights the strong power and cabling project, also attracts our attention.
