Connection mode:

1. The+12V and GND terminals on the access control host (powered by the access control host) are connected to the+12V and GND terminals of the access control power supply.

2. The positive terminal of the electric lock is connected to the NO or NC terminal of the access control power supply (depending on whether it is normally unlocked or locked), and usually connected to the NC terminal (power-on unlocking and power-off locking). The negative terminal of the electric lock is connected to the GND terminal of the access control power supply.

3. The button terminal (open signal) on the access control host is connected to the button terminal of the access control power supply. The door opening signals on the access control host are NO and NC, which are usually connected from the NO terminal of the access control power supply to the PUSH terminal.

4. If the other end is connected to the exit button, the two lines of the exit button are connected to the exit button end of the access control host, or to the pressing end and GND end of the access control power supply.

5. If the other end is connected to a card reader, the card reader is connected to the corresponding signal end of the access control host (generally connected to four terminals, 12V, GND, DATA0, DATA 1).
