    generally there is a bolt that is moved in the back, if its in position A then both locks must be ran, if in position B then either one can be ran...

    when i started working in stl, i had 4 banks that had the vaults set so that both locks had to be run, 2 years later now i only have one.... having to run both combos to open the vd is a huge NO NO.... not only do you lose redundancy but you are increasing your chances of a lock out, because both locks must work perfectly every single time.....


    btw most banks still do dual control by splitting the combo

    I'd assume that an automatic door can still be operated manually if there is a malfunction in the hydraulic system? That would be an unfortunate lockout, if the only poblem was topping off the oil.

    I don't mean to hijack the thread.

    Let me show my ignorance and ask; what is meant by redundancy in this context?

    Assuming a two-lock door, if it's set up so that either lock can open the door, that's redundancy. If one lock malfunctions, the other can be used to open the door. Whether the same person can operate both locks is just a matter of local policy.

    On the other hand if the door is set up to require both locks be unlocked, there is no redundancy. As jgriner pointed out, both locks must work perfectly every time.

    Somewhat rare is the three-lock door where any two of the three will open the door. This provides redundancy as well as dual custody (two people might be required, depending on local policy).

    There have also been four-lock doors but usually only on treasury doors.

    i converted a hydraulic door to a manual door once also in hop town ky, (technically it was nothing more than an electric motor, but it had always been referred to as a hydraulic) it had a clutch, that could be overpowered to use manually. as a matter afact that was the only thing i ever serviced on the door before the motor burned up. every couple of years i had to tighten the clutch.
