Operator system utilizing a position detector to initiate a closing sequence
摘要:
Mobile transmitter configured to control any compatible barrier operator so as to move an access barrier to a closed position based on the change in angular and/or linear position of a carrying device. The mobile transmitter includes a position sensor and an activity sensor to monitor the change in position of the carrying device. Thus, when the angular and/or linear position of the carrying device changes by an amount greater than a predetermined threshold, the mobile transmitter automatically communicates a mobile command signal to the barrier operator commanding it to close the access barrier.
