ABSTRACT OF THE DISCLOSURE The present invention is a device for detecting multiple input signals. The apparatus detects, for example, the decrease of air pressure in vehicle tires and so can be utilized as an air pressure alarm device for automatically giving a warning even when the vehicle is in motion. It comprises a signal detecting circuit including a plurality of signal carrier lines for carrying a plurality of AC input signals changeable electric characteristics such as levels, phases or frequencies upon occurrence of abnormality and a multi-input transformer having a plurality of primary windings connected to respective signal carrier lines and at least one secondary winding including an output secondary windings which are wound around an iron core having a common magnetic circuit and an output circuit for treating an output from the output secondary winding of the multi-input transformer. The primary windings in the signal detecting circuit are wound to magnetically cancel magnetic flux of said AC input signals when all of the signals are kept normal and connected between the signal carrier lines and the output circuits to produce an output at the output secondary winding upon breakage of the balance for magnetic cancellation when at least one of the AC input signals is in abnormality.
