FIELD: devices for object protection against intrusion. ^ SUBSTANCE: control device comprises code dialing unit, control unit, memory storage unit, code converter, shift register, code comparing circuits and outputs. Code storage unit outputs are connected with information inputs of shift register and corresponding inputs of control unit. The first output of control unit is connected to synchronization input of shift register. The second output of control unit is linked to synchronization inputs of code comparing circuits, which are used as device outputs. Outputs of shift register stages are connected to corresponding inputs of the first number of code comparing circuits. Inputs of the second number of each one are linked to corresponding outputs of respective code converter outputs. Code converter inputs are connected to corresponding memory storage unit outputs. ^ EFFECT: increased reliability and improved protection. ^ 6 dwg |
