The present invention relates to the field of the protection of safety enclosures, and it relates more particularly to the locking and unlocking of doorlock mechanisms, via a motorised bolt mechanism which is slaved via management electronics, particularly those of strongboxes, doors of strongrooms, doors or automatic ticket-dispensers, and other enclosures to be protected. This device also finds its application in the systems for controlling access to buildings or premises which are monitored (under surveillance), for which the doors are to be equipped with unlocking systems. <IMAGE>
