Door Access Control System Wiring Diagram is always important for your access control project, you must pay a lot of attention to it and make sure all wiring is connecting in the right way.

Also, the access control system wiring diagram includes a lot of wiring systems, like magnetic door lock wiring diagram, push to exit button wiring diagram, electric door strike wiring diagram and magnetic door lock wiring diagram and etc.

1, The wiring cables from the access control card reader to the access controller

We suggest using 8 cores stranded shielded twisted-pairs cable to connect reader and controller, (of which 3 cores were used as a backup. If it is unnecessary to feedback legal-card by voice and light of reader, we can disconnect LED cable). It is better to twist Data1 and Data0, and the sectional area should be above 0.22mm², the length should not exceed 100m. Shielded cable connect the GND of Controller. It is a good way to improve the performance of Reader by overstriking or compounding the cables. (Of course, other Cat5e Stranded SFTP cables can also be used).

2, The wiring diagram from a push exit button to access controller

we suggest to use 2 cores cable, the diameter is above 0.3mm²

3, The wiring cable from the electric door lock to access controller

We suggest to use 2 cores electronic cable, sectional area is above 1.0 mm². It is better to use less than 100 meters, and if the distance exceeds 50meters, we should use thicker cable or use multi-cable in parallel.

The cable from Door Contact to Controller, we suggest using 2 cores cable, diameter above 0.22mm². If you do not need to know more functions, such as knowing the door status online or alarming if the door was not closed for a long time and break-ins, then door contact cable can be uninstalled.

Communication cable :(from the controller to controller, controller to computer)

485 Communication Systems:

Cable from the controller to controller and controller to a transmitter, we suggest to use 8cores Shielded twisted pairs cable, the wire diameter is 0.22mm² or more 485+ and 485- must be mutually twisted, the rest 6 cores were backup, and shielded cable can be unconnected. If the communication runs smoothly, we can use shielded cable to connect the GND of a controller or install 120Ω terminal resistance to improve the communication performance between 485+ and 485- in the last controller of 485 total lines. Theoretically speaking, the length of 485 lines can reach 1200m, we suggest to use less than 800m according to the numbers of controllers or complexity of communication environment. If the length is over 800m, please use 485HUB or repeater to improve the communication environment. The connection between controller to the controller must be hand in hand type total line structure, resolutely eradicate branch or star connection.

TCP/IP Communication System

Same as internet structural cabling, we use a normal cable to connect a controller to HUB, distance is less than 100 meters. The longer the distance, the higher the quality of the line. We suggest using brand cables.

Other tips:

• All cables should be on the pipe in order to avoid any troubles caused by mouse, PVC or galvanized pipe are both OK.
• Although the controller designed with good anti-static, lightning protection and leakage prevention, please ensure that the controller cabinet and AC earth wire are connected perfectly, and the AC earth wire is grounded.
• Please do not often pull out the connector, please do corresponding welding work before you ensure to plug the connector.
• Please do not remove or replace the chip of the controller, an unprofessional operation will damage it.
• It is not recommended that you connect with other additional equipment without authorization. All unconventional operations, please be sure to communicate with our engineers.
• Please do not connect the controller and other large current equipment to the same power supply socket.
• The installation height of the card reader button is 1.45m away from the ground, which can be properly adjusted according to the customer’s using habits.
• The controller is recommended to be installed in a weak electric well, which is easy to maintain.
• Please pay attention to standard connection, do not expose the metal part too much, so as to avoid the short circuit and the communication fault.

There are many places where it is necessary to check out who can enter the place and who cannot! However, the problem is that it is simply difficult to control that if there are more than a hundred employees working out there. Then what is the solution? It’s simple, get an access control system installed.

A door access control system can systematically manage the privilege of employees and even visitors for getting entry to any particular place. They reduce the manpower need along with providing the necessary security that premises required.

Before thinking about the access control system installation it is necessary to know what features should an access control system have and what door access control system kits have. That is what you should look for while you shop for it from access control systems manufacturers and know door access control system price clearly.

1, Features to look for before investing in an access control system

While you visit any access control equipment suppliers make sure that you ask for the following features. This will ensure that you get the best one that will be most suitable for your premises.

• The system should be compatible with any third party hardware. Along with that, it must be free from any lock-in.
• The system should be able to support logical security.
• It should be in line with local standards and regulations.
• It must be capable of integration with the other security systems and the surveillance.
• It is better if it can be integrated along with the existing hardware which will reduce costs.
• It must be simple and easy to use.
• It should be easy to configure.
• It must be able to support the modern modes of communication, mainly the IoT.
• The network should be highly robust and reliable too.
• It must be affordable and the customer support must be good enough to help in case of emergency.

Based on the specific requirement of the organization there will be different types of access control system but ones with the above features will turn out to be an asset.

2, Buying an access control system

When it comes to buying an access control system there are many choices available. Many will prefer to buy them directly from the access control systems manufacturers while there are others who will prefer that it is purchased from dealers who will provide the best support in case there is some need in future.

Another good option for access control system installation is after buying them online. If you give the required keyword for buying an access control system you will find that there are numerous options available online. All you have to do is buy one that is most suited to your need.

However, before you buy it from any source it is necessary that you ensure that you have undergone the review about the access control system. There are available in different types and until and unless you read good reviews about the performance of the system it is not advisable to buy and install it.

Whether it’s biometric access control system or a proximity one it is necessary that before an access control system is purchased the requirement of the organization is well judged. This will help in choosing the right type of access control system. It’s not only the system but also the vendor who plays an important role while choosing the access control system. They should be large enough to provide you with the necessary support and small enough to care for your needs. It may sound odd but a very large company may simply ignore small purchases. Thus, ensure that you have gone through the reviews to know about the services of the vendor too, apart from the quality of the system.
