Abstract

A method for an alarm device with at least one so-called alarm washer arranged to be detachably fastened to an article by means of two parts, one on each article side, the washer in an active state emitting an audible acoustic signal, when said parts are separated. The method is especially characterized in that said audible acoustic signal is detected by means of devices (9) comprising at least one microphone (8) or similar, an alarm in appropriate cases being triggered during such a detection. The invention is also related to a device for performing the method.
