Advantages

How to use
Install AA batteries according to the polarity markings in the battery compartment. Clean and dry the intended mounting surface before applying the supplied adhesive sticker. Position the dummy alarm box at a visible height on an exterior wall in sheltered areas or inside a room to simulate an active alarm. After mounting, confirm the LED flash is operating to ensure the unit provides the intended visual deterrent.
