Abstract

PURPOSE:To make economical two-condition control by rendering the signals only into non-preferred condition even with a transmission passage having high attenuation and noises. CONSTITUTION:When an ''OFF'' command is fed to a repetition timer 11 at a key station A, an ''OFF'' signals are transmitted by a transmitting circuit 3. A branch station B has its receiving circuit 4 receiving the ''OFF'' signals and has its ''OFF'' restoring circuit 6 judging they are the ''OFF'' signals so that an output relay 10 is turned on through an off delay circuit 12. While the ''OFF'' signals are being repreatedly fed from the key station A, the output relay 10 of the branch station B keeps its conductive condition. If, on the other hand, the ''OFF'' signals are released at the key station A, the repetition timer 11 stops its operation to release the output relay 10.
