Abstract
An alarm system for a briefcase. A briefcase is provided with a radio receiver tuned to receive predetermined (such as coded) signals from a remote radio transmitter. The briefcase carries a siren, coupled to the receiver, to give an audible signal of a theft upon actuation of the remote receiver. The briefcase can also be provided with a handle which is normally secured to the briefcase, but which can be made to separate from the briefcase upon actuation of the remote transmitter. An additional mode of operation causes the siren to remain silent until the briefcase is removed a predetermined distance from the remote transmitter, the predetermined signals being continuously received until the briefcase is beyond the range of the transmitter. This mode of operation can also be employed to detach the handle when the briefcase is beyond the range of the transmitter.
