FIELD: remote control. SUBSTANCE: device for remote turning on electric equipment has telephone unit used as code typing unit, as well as connected in series decoder, decision making unit and unit to turn on actuator the output of which is the input for connecting the actuator, unit for threshold processing signals, the input of which is connected to telephone network and output to decoder input and additional input of the decision making unit. As this takes place the unit for threshold signal processing comprises connected in series units as follows: call signal rejection filter the input of which is the output of the unit for threshold signal processing, voltage divider and comparator, the input of which is the output of the unit for threshold signal processing, as well as reference voltage generator supplied between the call signal rejection filter and the second input of the comparator. EFFECT: higher reliability. 2 cl, 9 dwg |
