Interpretation of the three key points of installing access control systems

When installing an access control system , pay attention to the following three major areas:

First, prevent electromagnetic interference For readers, open the door button to pay special attention to anti-electromagnetic interference, especially lighting switches, electric typewriters and computers and other interference problems. If conditions permit, the reader should be installed at a distance of more than 30cm from the power source.

Second, to prevent the attenuation of the transmission signal The controller must be installed to take into account the distance between the controller and the reader, the ideal transmission distance is within 50m. For signal transmission cables, cable shielding and signal attenuation due to long-distance transmission must be taken into consideration. During the construction of the pipeline, the line pipe and cable tray made of steel should be used, and reliable grounding should be performed.

Third, the controller and system software debugging system debugging is to ensure the quality of the access control system, the key link. The focus is on the commissioning of the controller and the operation of the system software. The commissioning of these two parts must be carried out by the manufacturer at the same time. The function of the controller is to set the relay linkage output function according to the need besides the card reader input, the time and location of the alarm generation and start-up such as camera, alarm horn and so on.
