Abstract

A security device with bidirectional communication capability comprising logic control means which are adapted to control at least one LED for indicating the operating status of a peripheral unit in which the security device is accommodated. The device comprises at least one resistor which is connected in parallel to the at least one LED, for converting into voltage light energy received from the at least one LED, the LED being connected to means for evaluating the voltage generated thereby, the means being in turn connected to the logic control means.
