What problems should be paid attention to when going out the switch circuit? Thank you!
We recommend using two-core wire with a wire diameter of more than 0.3 square millimeters. When wiring, avoid walking with strong electricity to avoid other interference to the door opening signal, which may cause the access control to receive information incorrectly. Generally, most access control board use NO-type (normally open contacts) exit switches, when pressed, the two wires are short-circuited and send signals, when there is no press (usually), the two wires are disconnected.
