The mechanism comprises a bar (8) slidably mounted in a channel (18) which can be obstructed by a sliding member (11) of an electromechanical latching unit in accordance with a preset time-schedule. The device described enables the time ban to be lifted by means of two pivotal elements (43, 52) that are normally not coupled to one another, one of them being positionable in the path of travel of the bar (8) of the mechanism so as to be actuated thereby when the mechanism is moved in an opening direction. The two pivotal elements are associated with transmission means (50, 57) which are actuated when a breakdown is detected in order to lock the two pivotal elements together. The electromechanical latching unit can then be made inoperative manually by actuating the mechanism of the locking system in an opening direction.
For use in a coded and conditional-opening locking system having a locking mechanism, a device for lifting, in the event of a breakdown in the locking system, a time ban on the actuation of said locking mechanism, said locking system comprising an electromagnetic latching unit for blocking the locking mechanism and electronic control means for activating and deactivating the electromagnetic latching unit according to a time-schedule thereby enabling or disabling actuation of the locking mechanism during preset times, wherein said device comprises detection means for sensing a breakdown in said locking system and transmission means controlled by the detection means for making, in response to the detection of a breakdown, said locking mechanism mechanically drive said electromagnetic latching unit such that actuation of said locking mechanism will render said electromagnetic latching unit inoperative regardless of its operative state at the time of detecting the breakdown.
