Abstract: The invention relates to an actuating handle (17), provided with a preferably electromechanical locking mechanism (8, 8a), having a predetermined breaking point (4) which is between a handle neck (21) and a grip part (1) and is in particular monitored by an electrical switch (3) that preferably also acts as an “opening detector”. During authorised opening of the actuating handle (17), a programmed switch (A1) closes the circuit of the electrical switch (3), the circuit of the physical switch (A2) is then opened, and therefore the grip part (1) can be brought into an opening or tilted position without the alarm being triggered by the switch (3). After the actuating handle has been brought into the closure position, and after the electromechanical locking process (8, 8a), the switch (A1, A2) procedure is executed in a reverse sequence.

Abstract: Alarm-triggering locking plate for the closing area of a door or window to be secured, comprising a first breaking plate (4) to be overcome by force, having at least one stop element (3), comprising a second fixing means for the locking plate (1) which is more difficult to overcome by force, and is designed as at least one counter stop element (12) anchored on a door or window frame, and means which trigger an alarm when the first fixing means has been overcome, wherein a motion of the front retaining part (3) in the opening direction (8) of the door or window is limited by the second fixing means (12) when the first fixing means (4) has been overcome.

Abstract: An alarm-triggering locking mechanism for the lock and/or hinge area of a door to be secured or a window to be secured is proposed, which is embodied as a locking plate (23) which can be attached to a door or window frame by means of holding screws (27) embodied as the first blocking device. A second blocking device, which is harder to overcome by the effect of force, is embodied as at least one striker element (25) rigidly connected with the locking plate (23) and which, following the limited movement of the locking plate (23) in the opening direction, comes to rest against a counter-striker element (26) anchored on the door or window frame. An alarm, in particular a silent alarm, is triggered via radio or the telephone net after the first blocking device has been overcome. The burglar is thereafter delayed by the second blocking device, which makes it possible for security forces to reach the location of the break-in and to arrest the burglar while the break-in is still in progress.
