Installation of access control system: detailed explanation of wiring mode

Access control system is one of the necessary facilities in modern communities, enterprises and other places. When installing access control system, wiring mode is a crucial step. This paper will introduce the wiring mode of access control system in detail to help users better understand the installation method of access control system.

Wiring of access control host and access control power supply

The+12V and GND terminals on the access control host need to be connected to the+12V and GND terminals of the access control power supply to provide a stable power supply for the host.

Electric lock wiring

The positive end of the electric lock needs to be connected to the NO or NC end of the access control power supply. Generally, NC terminal is selected to realize power-on unlocking and power-off locking functions.

Wiring of exit button

The push end of the access control host is the door opening signal end, which needs to be connected to the push end of the access control power supply to ensure that the door can be opened normally. If the other end is connected to the exit button, the two wires of the exit button need to be connected to the exit button end and GND end of the access control host respectively; Or connected to the push end and GND end of the access control power supply.

Card reader wiring

If a card reader is connected, the wiring of the card reader needs to be connected to the corresponding signal terminal of the access control host (12V, GND, DATA0, DATA 1).

network connections

If networking is needed, RS485 line or network cable is connected to the access control host, and the other end is connected to the computer. Among them, RS485 line needs to be connected with serial port to RS485 converter and computer host serial port; The network cable is connected to the network port of the computer network card.

Wiring of other interfaces

There may be other interfaces on the access control host, such as alarm interface, doorbell interface, door magnetic interface, etc. , generally do not need to connect. If necessary, please visit it accordingly.
