Abstract: An access control system includes at least one door fitting to a secured area of a building and at least one identification code on a mobile data carrier. The identification code is read by a read device of a door fitting. If the read-in identification code is valid, access is granted to the area secured by the door fitting. An authorization code is transmitted from a processor via at least one communication connection to a central processor. A verification step is carried out to determine whether the transmitted authorization code corresponds to a valid authorization code for an area profile. Upon successful verification of the transmitted authorization code, write and read rights for the area profile are released to the processor transmitting the authorization code. The released area profile is changed by the processor via a communication connection.

The control device actuates the electric motor so that a displacement velocity of the at least one door panel is substantially constant over the entire displacement path between the open position and the closed position of the door panel.

Abstract: A method for triggering an elevator brake in an emergency situation of a vertically movable elevator car in an elevator installation, wherein a movable part of the brake is held in a starting position by an electromagnetic force generated by a coil connected with a voltage source, and for triggering the brake the voltage supplied to the coil is interrupted and the movable part is moved from the starting position to a braking position by a spring force of at least one spring. A voltage is set by a switching unit that is connected with a control unit in dependence on at least one travel parameter of the elevator car determined by the control unit and, in the case of failure of the voltage source, triggering of the elevator brake is delayed by a delay unit in dependence on the set voltage.

Abstract: A method of controlling access to an area accessible by persons, particularly to a space closed by a door, utilizes a first mobile communications unit on which at least one access code is filed and a receiver unit for receiving the access code. In a first variant of the method, when an activation signal is transmitted by the communications unit within a predetermined range of the receiver unit, the receiver unit is activated and the access code is transmitted from the communications unit to the receiver unit. After a successful check of the access code by the receiver unit the access is freed. In a second variant, when the activation signal is transmitted by the receiver unit within a predetermined range of the communications unit, the receiver unit is activated. The access code is subsequently transmitted from the communications unit to the receiver unit and after a successful check of the access code by the receiver unit the access is freed.
