ABSTRACT A radio remote-controlled door operator for use, among other uses, as a residential garage door operator. The transmitter contains two buttons, one to produce normal door operation and the other to set the operator into a "secure" mode wherein it will be non-responsive to further valid operating codes until reset. In addition, a second deeper level of security may be established by means of a vacation switch which disconnects the operator from the AC power supply. The operator system comprises a microprocessor which is programmed to perform various accessory functions even though the accessories may not be present. Various microprocessor inputs are tied to a false "safe" level so that even though the accessory programs are run, no outputs result and no interference with normal door operation is produced.
