Remote control unit for time sharing multiplex transmission

Abstract

Abstract PURPOSE:To compulsively control the terminal unit in failure, by providing the operation unit forming forced signal at the private two-cored cable, providing the return signal reception retransmission circuit at the central control panel, and providing the address discrimination section and the forced control signal reception section at the terminal unit. CONSTITUTION:The operation unit 12 is provided with the private two-cored cable 2 for the time sharing multiplex transmission remote control unit. This operation unit 12 detects the call-out of the terminal unit in failure at the terminal logic circuit 7, and control signal is formed at the forced control signal section 10 and delivered. Further, the central control panel is provided with the return signal retransmission circuit 9 and the said control signal is retransmitted to the terminal unit via the driver 93 at the return signal reception time band. In the terminal unit, the address discrimination section detects the coincidence of the address of control signal and the address of itself and the control signal is received at the forced control signal reception section perform ON-OFF control of the forced control relay.
