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.

A remote control system for use in combination with a conventional telephone and associated telephone lines for transmitting actuating signals to a controlled device comprising: dialing data detecting means coupled with the telephone lines providing telephone service in a premises for detecting dialing data from the lines; first decoding means connected with the dialing data detecting means for detecting a programmed access code from detected dialing data; second decoding means also connected to the dialing data detecting means and enabled by the first decoding means when the programmed access code has been detected for detecting a device code from the dialing data and producing an actuating signal for a controlled device; ring counting means coupled to the telephone lines on the premises for counting the number of rings on an incoming line from distant calling stations; ring count decoding means connected with the ring counter for detecting ring counts corresponding in number uniquely with a controlled device and producing an actuating signal; and actuating means coupled to a controlled device and responsive to one of the actuating signals from the second decoding means and the ring count decoding means for actuating the controlled device in accordance with the signal whereby a controlled device can be actuated from both distant stations and telephones on the premises.
