Anti-theft device for intercom systems

摘要

A module frame for bell system modules having a module locking means for locking modules, which are to be inserted, to the frame and having a locking canceling means for canceling locking during actuator excitation. In the process, provision is made for the locking canceling means to also exhibit actuator-independent permanent catch blocking which can be selectively activated.

主权项

1. A module frame for bell system modules comprising:
a means for locking modules, which are to be inserted, to the frame and, a means for canceling locking during actuator excitation, wherein the means for canceling locking also exhibits actuator-independent and selectively activated permanent catch blocking, wherein the means for locking comprises a linearly moving element and a rotatable element, said rotatable element, in at least one rotation position, pushes the linearly moving element into a first linear position for permanent catch blocking and which, in at least a second rotation position, allows movement of the linearly moving element into a locking position, in such a way that the excitable actuator can move the linearly moving element out of this locking position.
