The connection terminals of the special power supply for access control generally include the following: power output +12V, power output GND, switch control signal input push, electrical signal control input control+ and control-, normally closed electric lock control output NC, Normally open electric lock control output terminal NO, where the power output terminal +12V and power output terminal GND are connected to the +12V and GND of the access controller or all-in-one machine;
The power output terminal GND and the switch control signal input terminal push are connected to the door opening button and the door opening switch signal output by the access control. Note that this interface can only be connected to a pure switch signal. If the signal has power, it will be troublesome. The control part of the power supply may be blocked. burn. Sometimes several devices need to control the electric lock at the same time, as long as the pure switch signal can be directly connected in parallel to achieve common control; the electric signal control input terminals control+ and control- are connected to the electric signal for controlling unlocking output by the access control or building intercom, if the device If the control output is an electrical signal, use these two ports, and the voltage must be between 5-12V;
The control output terminal NC of the normally closed electric lock (such as magnetic lock, conventional electric mortise lock, power-on lock type cathode lock, etc.) of the special power supply for access control is connected to the positive pole (red line) of the normally closed electric lock, and the negative pole (black line) of the electric lock ) is connected to the GND of the special power supply for access control; the control output terminal NO of the normally open electric lock (such as electric control lock, power-on unlocking type cathode lock, etc.) is connected to the positive pole (red line) of the normally open electric lock, and the electric lock The negative pole (black wire) of the access control is connected to the GND of the special power supply for access control.
What needs special explanation is the control of the electric control lock. There is no difference between the positive and negative of the two wires. As long as one is connected to the NO terminal and the other is connected to the GND, it is enough. When connecting the electric control lock, special attention must be paid. First of all, the special power supply for access control and the door opening delay of the simple access control all-in-one machine should be adjusted to the minimum, otherwise the high current of the electric control lock up to 3A is like a flash flood, and the connected equipment will be burned.
