This machine features a serial signal strength based combo lock, it is set to be able to handle 4 digits, however it is easily expandable with each digit being 4 blocks wide.
The set combo right now is 1234, you can only change the combination when you have the correct password entered. There are a total of 11 buttons and 1 lever, the lever is used to change the set password, the wooden button clears the current memory, while the 10 stone buttons are digits 0-9. It is spam proof, however it wont pick up on inputs if you do spam it. There are 3 redstone lamp outputs, the leftmost is when you are changing the password, the middle is if you are clearing memory, and the rightmost is if the current pin is correct.

There are no sign or map labels at the inputs and outputs of the building. Making judging it extremely difficult.
I assume that a WE action removed them. Please add them back again, so that your building can be judged.
Every output and input should be labeled.
