I've got to ask the obvious stupid questions, If it's a true emergency door, it would open to the inside of the vault, Correct? Why would they have a time lock on the door? Would the time lock on the emergency door match up time wise with the main vault door? It looks from the pictures that someone could access the time lock on the emergency door from outside the vault and there by removing the inside cover to access the lock mechanism to open the door from the outside. If the door opens to the outside of the vault, it would be in my opinion be a secondary entrance, not so much an emergency door. Mark
