Abstract
A system for activating an object actuating system coupled to a movable object such as a gate or garage door includes a user command transmitter that is manipulable by a person to generate a signal representing an identification and a command. A repeater receives the signals from the command transmitter and in turn, in the presence of a valid ID, sends a command signal to the object actuating system, which in turn moves the object only if the ID from the repeater (which can be different from the ID from the command transmitter) is valid.
