Claim:
A method of contributing a security network including two or more alarm devices to form said security network when said alarm devices come within a security distance of each other that said alarm devices are non-programmed or users of said alarm devices do not know each other, each of said alarm devices comprising a portable case receiving at least a sensor, and alert signal generator and a radio frequency (RF) transmitter which are electrically connected with a control processor, wherein the method includes the steps of: (a) locating said alarm devices at different locations having said security distance between each other; (b) communicatively networking said alarm devices with each other through radio frequency (RF) signals to contribute said security network such that when one of said alarm devices is located within said security distance of another said alarm device, said alarm devices detect each other to contribute said security network; (c) setting at least one of said alarm devices in a standby condition, wherein each of said alarm devices functions as an independent alarm device to generate an alert signal from said respective alert signal generator when said respective sensor is triggered, and; (d) activating said control processor unit of one of said alarm devices to send a RF action signal to said other alarm devices to activate said other alarm devices within said security network to generate said alert signals from said alert signal generators respectively when said one of said alarm devices is triggered.
