System and method for unattended control of an access barrier
First Claim
1. A system for unattended auto-close control of an access barrier comprises:
- a barrier operator to move the access barrier between opened and closed positions, said barrier operator having a timer set to an initial count value, said timer being periodically updated toward an expired count value when the access barrier is moved to an unclosed position; and
a transmitter configured to automatically and continuously send an auto-close signal at periodic intervals to said barrier operator;
wherein the access barrier is moved from an unclosed position to said closed position, when said timer has reached the expired count value and said barrier operator receives said auto-close signal.

Abstract
A system and method for unattended control of an access barrier comprises a barrier operator having a timer capable of being updated at predetermined intervals. The barrier operator is configured to receive an auto-close signal that is periodically sent from a wall station, keyless transmitter, or remote transmitter that is compatible with the barrier operator. When the auto-close mode is invoked, the barrier operator initiates the timer when it detects that the access barrier has been opened. As such, the access barrier is closed via the barrier operator when both the timer has expired, and the auto-close signal is received by the barrier operator from one of the transmitters.
