ABSTRACT:
A remote control system connected to subscriber telephone lines serving a premises utilizes telephones to transmit dial-coded command signals to a central control unit where the signals are converted into actuating signals for specified devices elsewhere on the premises. The actuating signals are transmitted as pulse modulated carrier waves through utility power lines serving the premises and the devices, and specifically tuned receivers on the lines detect the appropriate actuating signals and cause an associated device to be actuated. The system also responds to ring pulses from telephones located off the premises and produces the same actuating signals for controlling the devices on the premises from distant stations.
