PROBLEM TO BE SOLVED: To easily attach and detach the warning unit by welding a base where the warning unit is fitted to a window frame and enabling the warning unit to be attached and detached. SOLUTION: The base for fitting the warning unit 1 to a sash window which is thick enough to open and close including an adhesion part is adhered to the window frame. Thus, the base is adhered to the window frame and the warning unit 1 which has the pin 2 inserted into a groove is inserted into the base from the right to the left. When the window is opened, the warning unit 1 moves to the left and the pin 2 is caught by the base to come out, so that the warning unit 1 sounds. Consequently, crime prevention is achieved only by fitting the alarm unit to the sash window. Then the warning unit solves the problem that the window is opened and closed inconveniently.
