CA 2598560

The invention relates to a window or door handle: with a handle (4) mounted in a handle fitting (2); an autarkic monitoring/alarm module (1), which is arranged in a module housing (26) and which has a number of sensors (8, 14, 15), and; an evaluating unit (24) that receives the alarm signals and detection signals. The invention provides that the monitoring/alarm module (1) has at least one structure-borne noise sensor (15), which is integrated in the module housing (26), is oriented toward a glass pane (34) and which selectively detects sound frequencies resulting from broken glass, and which transmits an alarm signal to the evaluating device (24) in the event of a breaking of glass.

L'invention se caractérise en ce que le module de surveillance et d'alarme (1) présente au moins un capteur de bruit de structure (15) intégré dans le boîtier (26). Ce capteur est orienté en direction d'une vitre (34) et détermine de façon sélective des fréquences acoustiques générées par un bris de glace et, en cas de bris de glace, il transmet un signal d'alarme à l'unité d'évaluation (24).
