Details of the problem:
Hello, I am a landlord, I bought a MC-203E electric door lock from your company, now it can be used normally, but I live on the 3rd floor and always go to the first floor to open the door when I have friends, I would like to ask if it is possible to open the door to the third floor, so that a friend will come over and the door will be opened by pressing the switch, if possible, how do I need to wire it? Thank you
