Expert answer:
We recommend use two core lines with a diameter of 0.3mm above. When walking along the line, avoid the power to walk with the strong power, and avoid others interfere the signal of the exit button. If something goes wrong , it will lead to the access control to receive the wrong information. Generally, most of the access controllers adopt the NO type switch exit button (the touch point is often open type). When pressed, the two lines short-circuit and send the signal. When it is not pressed (normal），the two lines are disconnected.
