Abstract:
1. A discrete add-on processing system adapted to be connected to a barrier operating system which includes a barrier operator that moves a barrier between open and closed positions, the processing system comprising: at least one mobile transmitter automatically and periodically generating both a close mobile signal and an open mobile signal regardless of location; a barrier position indicator generating a barrier position signal; and an add-on controller adapted to be connected to the barrier operator of the barrier operating system, said add-on controller receiving both said mobile signals and said barrier position signal so as to enable the barrier operating system to open the barrier after receiving said open mobile signal and after having not received said open mobile signal for a period of time if said barrier position signal indicates that the barrier is in a closed position, and close the barrier after receiving said close signal and after having not received said close mobile signal for a period of time if said barrier position signal indicates that the barrier is in an open position.
