Yanteng ID card access control system how to install the wiring

First, the installation of wiring 1, card reader to the controller's line is recommended to use copper shielded wire, wire diameter of 0.3 square millimeters or more. The maximum length cannot exceed 10 meters. To read the card, it is advisable to use the card to be close to the card reader. The method of quickly scanning the card with the ID card from the side is not desirable and does not guarantee the success of brushing the ID card.

The installation of the ID card reader is better not to be installed on the metal surface. Since the ID card reader is an RF product, metal in front or in the back will absorb its RF signal. If the metal surface is large, it will even affect the reading of the ID card. No information is available to the device, or the reading distance is greatly attenuated. In addition, the proximity of two ID card readers will also affect each other, some will shorten the reading distance, and some will cause the two readers to read the card at the same time or the card reader cannot read the card. The solution is: try not to install on the metal surface, or to dig away the metal part of the card reader and keep the distance between two ID card readers above 25c.

2. The line to open the door to the controller is recommended to use two core wires with a wire diameter of 0.3mm2 or more.

3, the electric lock to the controller's line is recommended to use two-core power cord, wire diameter of 1.0 square millimeters or more. If more than 50 meters to consider using a thicker line, or multiple strands in parallel, or through the power supply fine-tuning button, increase the output voltage to about 14V. Do not exceed 100 meters in length.

A section of the line from the electric lock to the controller in the construction of the access control looks very ordinary. If it is not standardized, it is easy to cause the fault phenomenon that is difficult to find. This must be taken seriously!

Because the operating current of the electric lock is relatively large (as opposed to other devices of the access control system such as the controller and the ID card reader), the electric lock is sometimes installed at a certain distance from the controller, and the voltage drop on the line may be relatively large. If the pressure drop is too large, the electric lock can sometimes be held in motion, sometimes with no movement. Magnetic locks are sometimes not enough suction. The performance of the door switch is not normal. Even with the controller to grab current resources, making the controller power supply is insufficient, restart or even crashes.

Some engineering personnel have convenient wiring or convenient purchasing. It is very easy to cause faults by using the network cable to electrically lock the wires of the controller. Although it seems that there is no problem during debugging, after a while, problems will often arise. .

If the line length is less than 50 meters from the electric lock to the controller, a two-core power cord with a cross-sectional area of ​​1.0 mm2 is required, and no shielding is required. If it exceeds 50 meters, double the power cord of the two cores and supply the power in parallel. If the line length is greater than 100 meters, it is recommended to move the controller closer to the door lock to shorten the wiring distance. The cross-sectional area of ​​the network cable is 0.2 square millimeters, which is 5 times smaller than our standard wire, so it is absolutely impossible, even if the controller is close to the electric lock.

Electric magnetic signal cable, you can use network cable. Some people, the four strands of the network cable, supply power to the electric lock. Although it is theoretically close to the norm, it is not recommended that you do so. Doing so will make the terminals unstable and other hidden dangers.

4. Magnetic wire to the controller is recommended to choose two core wires with a wire diameter of 0.3mm2 or more. If you do not need to know the on-off status of the door or do not need to open the alarm and illegally enter the alarm function for a long time, the magnet wire may not be Then.

5, TCP / IP communication line controller to the server, and the controller to the converter line, are TCP / IP communication lines. 8-core shielded twisted pair cable is recommended. The wire diameter is more than 0.3 square millimeters. The TCP/IP bus length can theoretically reach 120 meters. It is recommended not to exceed 100 meters depending on the number of controllers or the complexity of the communication environment. If more than please use a router to improve the communication environment.

If the TCP/IP cabling is not standardized or exceeds the communication range, the communication may not be able to communicate or sometimes the communication may not be able to communicate.

Second, wiring construction considerations All the wiring must be casing, PVC pipe and galvanized pipe can be, to avoid rat bite off the line caused by failure. Although the controller has a good design of anti-static, lightning and leakage protection, please ensure that the controller chassis and the AC ground wire are connected perfectly and that the AC ground wire is grounded.

It is recommended not to always remove and insert the terminal block. Always unplug the terminal and perform the corresponding installation work.

Do not disassemble or replace the controller's chip without authorization. Non-professional operation will damage the controller.

It is not advisable to dock other additional equipment without authorization. All unconventional operations must be communicated to our engineers beforehand.

Do not connect the controller and other high current devices to the same power outlet.

The installation height of the ID card reader is 1.45 meters above the ground, which can be appropriately increased or decreased according to the customer's usage habits.

The controller is recommended to be installed in a well-serviceable location such as a weak electric well.

The wiring terminal should pay attention to the standard wiring. Do not expose the exposed metal part too long to avoid short circuit and communication failure.

If you need to save the access control event record, read the data from the controller periodically.

Depending on the application, the power-off processing measures such as UPS power supply are used.

Pay attention to the use environment of this product.

The distance between the ID card reader and the controller should not exceed 10 meters.

Distance between computer and controller: TCP/IP 100m

The input/output current of the controller is relatively small. When the project is commissioned, if the instantaneous electric shock of the used electric lock is too large, causing the controller to restart, it is recommended to connect a 2200μF/35V electrolytic capacitor in parallel with the power cable of the electric lock. (especially when multiple locks are connected to the same power supply, either the power headroom is increased or several bulk capacitors are added)

It is best not to use the same power supply port for the electric lock and controller. (Our access controller is a lock-up power supply. This power supply is designed as a dual power supply. The actual controller power supply and the lock power supply are separate, but the conservative approach is to connect up to two magnetic locks.)

The controller power supply must use a linear power supply. Because the effective power of the linear power supply is not high, the self-heating is severe, and the effective power is generally 40-70%. The nominal 5A power supply has an effective current of about 3A. However, the linear power supply operates stably with less interference and is suitable for long-term stable operation of equipment. It is the type of power source commonly used at home and abroad access control equipment. Some projects ask whether switching power supply can be used. The power of switching power supply is large and the effective power is high. We do not recommend using switching power supply. Switching power supply generally has high high-frequency ripple, which will affect the stability of the host's operation (especially Is communication). But it can be used as a lock power supply.

For places with strong magnetic interference, use galvanized steel pipes or closed metal trunks for laying and grounding.
