Abstract: A lock with a door handle and/or an anti-panic bar, which is/are operatively connected to a follower that can be coupled and uncoupled, with an electromechanical energizing unit and at least one sensor for the access control of a door, where in an uncoupled condition of the follower, the follower is in a contact position with the sensor, and wherein by activating the electromechanical energizing unit, the follower can be transferred into a coupling condition, wherein, in the coupling condition, the follower releases the sensor into a release position by actuating the door handle and/or the anti-panic bar, where the follower includes an arm with a rotatably supported actuating element, where, in the coupling condition, by actuating the door handle and/or the anti-panic bar, the actuating element releases the sensor from the contact position into the release position.
