<p>The method relates to an alarm system, in particular for a motor vehicle, for protecting the latter against break-ins and thefts. According to this method, for each part or accessory of the vehicle to be protected, a device for the electrical detection of an alarm condition (BE2, BE3, BE4) is provided, these detection devices are connected to an alarm device (AL), and the electrical arrangement is supplied with energy from an energy source such as the battery of the vehicle. The method is characterised in that at least some detection devices are designed so that each detected alarm condition gives rise to a sudden variation in the current consumption at the terminals of the battery, detects these variations at these terminals (at BE1) and uses the electrical signals of such sudden variations in order to activate the alarm device (AL). <IMAGE></p> |
