ABSTRACT:
A control system for remotely activating an automatically opening door according to the present invention includes a plurality of transmitters held by different people and each transmitter transmits control signals. The system further includes a plurality of doors at least some of which are mounted in different buildings. Each of the doors includes an actuator for automatically opening and closing the door and a receiver electrically coupled to the actuator for receiving control signals from the transmitters and activating the actuator to open the door in response to the receipt of the control signals. In this system, any one of the transmitters may be used to open any of the doors.
