Diversionary device

A multi-burst diversionary device comprising a housing having an outer housing portion with a side wall region defining a central longitudinal axis and end closures at opposed ends of the side wall region to define an internal cavity within the outer housing, a mounting arrangement holding two or more replaceable pyrotechnic cartridges within the internal cavity, each cartridge comprising a housing containing a pyrotechnic charge and a fuse with a time delay, the device having an ignition cap mounting a primer charge and a firing arrangement for selectively detonating the primer charge mounted to a first of the end closures, a fluid passage defined in the first end closure through which a proportion of a flash of heat and pressure given off by said primer charge in the ignition cap when it is fired is directed toward the fuse of each cartridge, the mounting arrangement comprising an inner housing portion located inside the outer housing portion, the inner housing portion having a plurality of chambers, each containing a respective pyrotechnic cartridge, the device having a flash divider for directing a proportion of the flash from the fluid passage on to the fuse of each of the cartridges, the flash divider comprising a projection on one end of the inner housing portion proximal to an outlet end of the fluid passage and which is shaped to direct a proportion of the flash on to the fuse of each of the cartridges.
