The invention relates to a closing system ( 1 ), comprising a transmitter/receiver unit for the non-contacting operation of a door ( 2 ) or a gate, as well as to a method for its operation. In order to operate a door ( 2 ) or a gate, a transmitting code is transmitted by an authorized transmitter ( 3 ) to the receiver ( 4 ). The authorized receivers ( 3 ) are defined in that their transmitting codes can be read into the receiver ( 4 ) by means of a teach-in mode. The receiver ( 4 ) can be switched to the teach-in mode upon receiving an identification code from a freely selectable transmitter ( 3 ) if the number of transmitting codes for authorized transmitters ( 3 ), stored in the receiver ( 4 ), is below the limit value (N<SUB>G</SUB>) predetermined for the receiver ( 4 ). The receiver ( 4 ) can be switched to the teach-in mode only upon receiving an identification code from an authorized transmitter ( 3 ) if the number of transmitting codes of authorized transmitters ( 3 ) that are stored in the receiver ( 4 ) corresponds to the limit value (N<SUB>G</SUB>). |
