This is a simple door lock circuit.Use push buttons for up and down. The code is 8 up C down. When the door opens, the yellow light will start blinking .The system will give you (2min14s or the upper 7 segment display will count until F), to do what you got to do before it stops, locks the door, puts a default code and sends a closed door message to the operator followed by a red light. Only the emergency push button can turn the red light off and reset counters.

1=0001 and 3=0011. So the inverse reading order would be 1000=? and 1100=? it is just to review digital logic.
