Abstract
A device for actuating an electromagnetic elevator brake in an elevator installation includes at least two outlets connected to a coil of the brake, and a control system. Also provided is a switchable dissipation device, which is connected to the two outlets. In a rapid actuation operating mode, the control unit switches the switchable dissipation device such that the magnetic energy stored in the coil dissipates rapidly. Rapid actuation of the elevator brake is thus made possible.
