No. 2024062 IPC G08B17 / 00) 2, in which the sensors are connected in parallel through the interface units and through a three-wire beam are connected to the central console via an optocoupler. When the sensor is triggered, each pairing unit generates a zero zero current of a certain duration, which determines the total number of the triggered sensor, then when several sensors are triggered simultaneously, this information is transmitted to the beam sequentially, which eliminates the loss and distortion of information. The central iiyjn.i is galvanically isolated from the sensors, the interface unit and the beam, and in the central panel, the identification of the triggered sensor is identified using the pulse selector. Useful information, namely, the sensor number in binary form, is read by the counter and written to the register.
