Abstract

The device is placed in the interior of partitions such as doors, floors or walls so as to detect and signal attempts at burglary. Fitted in the interior of and in the plane of the partition is a sheet of insulating material (6) covered with an electrically conducting sheet (7, 8) on each of its two faces. The two conducting sheets (7, 8) are connected to the terminals of a low power battery (11) and of an electronic control unit (12) which initiates triggering of an alarm (13) for a given time, as soon as contact is established between the two metallic sheets by the introduction through the wall or partition of a metallic tool (14).
