Alarm device, of the type that involves a relay or any device, electronic capable of closing a power circuit, because of the lack of voltage between the steering terminals; essentially characterized in that one of the steering terminals is directly connected to the voltage source, while the other during part of its travel is embedded in a transparent body, plastic, glass or other analogous, so that the breakage of the body transparent causes the breakage of the embedded conductor and the lack of voltage in the steering terminals of the relay or similar electronic device, causing the closing of the power circuit that feeds any of the known devices that transform the electric power into sound.
