AbstractA security dye pack disguised as a bundle of currency for deterring robberies includes a housing formed from a stack of currency bills sewn together and having a hollow chamber formed therein. A printed circuit board is disposed within the chamber for supporting electrical components which generate an actuating signal upon detecting removal of the security dye pack from the protected premises. A flexible pouch containing dye, tear gas, or other active chemicals, is secured at one end of the printed circuit board, and a squib extends into the pouch to ignite the chemical mixture when the actuating signal is generated. The flexible pouch is formed of a heat-resistant plastic film which is easily bendable. Foam cushions, protected by heat-resistant film, are disposed above and below the pouch and circuit board. Heat resistant plastic sheets extend about the foam cushions and are secured by an elastic thread to the housing to retain the components within the hollow chamber.
