The Hollar Model 2 used an electrical system to allow the operator to keep the time lock on guard indefinitely. This was seen as a contingency in the case of civil disturbance or even invasion, where the vault door may need to remain closed past the maximum 72 hours available on the timer movements. The system uses 4.5 to 4.75 VDC, at about 1 amp. See more photos of the restoration of this time lock here: http://www.my-time-machines.net/hollar_model_2_restoration.htm.
