Abstract
A rolling code transmitter is useful in a security system for providing secure encrypted RF transmission comprising an interleaved trinary bit fixed code and rolling code. A receiver (202) demodulates the encrypted RF transmission and recovers the fixed code and rolling code. Upon comparison of the fixed and rolling codes with stored codes (220) and determining that the signal has emanated from an authorized transmitter, a signal is generated to actuate an electric motor (234) to open or close a movable barrier.
