As an indispensable part of security, the Access Control System carries the security management of the entrance and exit, and provides users with convenient and convenient use experience.The access control system has been applied to our construction, family and property management as the leader in the field of channel security. The access control has been installed for many years, and there will be some troubles in the future without maintenance. How should we deal with these faults? In recent years, the functions of access control systems have become more and more abundant, the technical thresholds have become higher and higher, and the reliability has become higher and higher. How should managers maintain the access control system?

With these questions, FCARD Xiaobian will give you some doubts.

The access control system exists in the form of a visitor building in a high-rise building. It not only increases the user's long-distance intercom, but also provides information exchange and management. And if such access control systems fail, how should we conduct troubleshooting? Thanks to the Video Door Phone, it has a multi-function such as doorbell, monitoring, intercom, and remote door opening. Users tend to have a complex sense of maintenance. In fact, its overall troubleshooting is not that complicated.

When the user cannot unlock, we need to check the access control power supply of the access control system to check whether the connection from the power supply to the Access control power box is bad. Secondly, check whether the unlocking line is connected properly. Generally, the link line of the building access control system has There are a number of wires, and the main control door lock is a 2-wire cable. It is also necessary to check whether a compliant communication cable is used. If a substandard communication line is used, the transmission signal is weakened and may cause a line failure. In particular, access control devices with a communication distance of more than 100 meters.

Treatment method: According to the instructions of the building intercom access control system, use the correct wiring method, and select the transmission communication line that meets the transmission distance. If the door-to-door access lock can be opened normally, it is proved that the working status of the building access control is normal.

Another problem faced by another new user is that after the whole set of access control system is installed, the power indicator is normal, but the electric lock is not locked. At this time, the user often thinks that the electric plug is connected with the battery, and the electric plug can be used normally. So what are the other reasons for this?

Troubleshooting and processing methods: For this kind of fault, we analyze from multiple angles. Firstly, the voltage is not enough, which will cause the electric plug to not work properly. Secondly, the head and the lock sensing area are not correct; the power supply is positive and negative. There is no good thing; the communication line does not select the wire of the specification, which leads to insufficient current; and the wire with a distance of less than 50 meters is specified as 1.0MM wire, so that the power supply voltage and current are not enough.

In short, the fault maintenance of the access control system requires the user to carefully discover that the access control system can serve us according to the user's needs and the reasonableness of the access control equipment.
