Precautions for Wiring and Installation of Access Control System_ Taigewang Technology

There are few devices to be installed in the access control system. Generally, they are controllers, card readers, electric control locks, doorbells, etc. it seems that the installation is very simple, but in fact, it is not. Just wiring needs to pay attention to many places. If it is a little careless and careless, there may be all kinds of small problems, which will bring inconvenience to future use. We are summing up our years of installation experience and hope to help you. 1、 The wiring of 485 controller shall be constructed according to the specifications. Wiring is the basic requirement of all installation work, but there are few installation personnel, which are convenient and not strictly implemented. The following wiring specifications must be noted. 1. All communication lines must use twisted pair or network cable, and shielding is better. 2. Parallel lines shall not be used for communication line wiring. Even if the line is short, do not try to facilitate the use of parallel lines, because parallel lines are the biggest hidden danger of communication problems in the future. 3. The communication lines shall not be forked or connected in parallel, but must be connected in series. It shall not cause interference and affect communication. 2、 Link between controller and electric lock. If the controller and electric lock are connected directly (not through external power supply), pay attention to the wiring distance. If the distance is within 50m, a power line with a cross-sectional area of 1.0mm2 must be used; If it is more than 50 meters, the wire must be thickened and can be twisted into one with two strands. If two locks are to be installed on the door, they must be wired, not collinear. Finally, some installers are greedy for convenience and directly use the network cable to connect the electric lock. This practice is wrong and should not be used. 3、 Connection between card readers the joints between card readers cannot be simply screwed together by hand, which is easy to cause poor contact. They must be welded and firmly connected, and then wrapped with insulating cloth or heat shrinkable tube (the effect of heat shrinkable tube is better). 4、 Wiring line wiring in order to be beautiful, try to take dark lines, and the lines must also take pipes, which is a necessary measure to prevent rats from biting. If they are bitten by rats, it is very troublesome and difficult to rewire (because some lines are sealed). 5、 The power supply for the access card reader and controller consumes very little power, and the power consumption of the electric lock is relatively large. We summarize as follows: 5A linear power supply can only carry 4 conventional electric locks 4 card readers 1 controller at most. 5A switching power supply can only have 8 conventional electric locks 8 card readers 1 controller at most. In order to ensure sufficient power, it is best to use the original power supply. It is also recommended to buy brand power if it needs to be purchased.
