The invention relates to a safety circuit, particularly for door locks, and to devices equipped with such a safety circuit, particularly locking mechanisms. The safety circuit comprises a sensor (4) switched between a controlled circuit (1) and a sensor input (SE) of a trigger circuit (2). The trigger circuit (2) comprises at least one data input (A, B), by way of which data comprising a representation of a target state of the controlled circuit (1) is fed to the trigger circuit (2). The invention further comprises at least one control output (SA). The trigger circuit (2) is equipped to determine, in a reactionless manner, on the basis of input signals from the sensor (4) and the data, whether or not the controlled circuit (1) is in the target state. The control output (SA) is coupled to the controlled circuit (1) such that the trigger circuit (2) is able to move the controlled circuit (1) into the target state in a reactionless manner, if it was determined that the controlled circuit (1) is not in the target state. |
