ABSTRACT:
A portable strong box device with a self contained acoustical alarm for protecting from theft valuables in the home, hotel room, motor vehicle or other locations where a suitable external electrical power source is available. The purpose of the external electrical power is to hold off the acoustical alarm until the external power is interrupted. Upon interruption of the external electrical power, the acoustical alarm, powered by a battery contained within the alarm system will be sounded. To further prevent any attempt to move the strong box from where it has been placed, a high strength cable is provided that may be wrapped around any convenient object that cannot be easily moved. As a portable device, easily carried in a suitcase for example, it does not require mounting by means of screws or bolts to an adjacent surface.
