ABSTRACT:
A device for use as an alarm for detecting the unauthorized opening of a sliding door or window is disclosed which is a wireless electronic alarm device which may be easily installed either horizontally or vertically in the casing of a sliding door or window to resist forced opening of the sliding door or window while simultaneously sounding a highly audible alarm signal indicative of an attempt to break in. The alarm device is of lightweight, portable construction in a tubular design which acts to substantially forestall the opening of the sliding door or window without the application of force sufficient to break the door or window. Once triggered, the alarm will continue until the unobtrusive owner-activated reset switch is activated to disarm the device.
