I do but it might not make sense with everything on it. I can try to explain it though:
We have electronic locks with a relay inside them. This relay has a common and then an open or closed position. When the lock is engaged the common (white wire) is tied to the closed position (green wire) creating a closed loop and when the lock is not engaged the common (white wire) is tied to the open position (brown wire not in use). They tied in the black wires from that "thing" into our common (white) and closed position (green) wires and added "something else: light bulb, some type of switch" to notify them when the locks were engaged and the door closed.
I have to go back and test our locks but wanted to figure out what that "thing" is before I went so I won't be guessing as to what it does.
