Abstract
A fire extinguishing apparatus has a structure defining a first chamber containing an electrically operable explosive device, a piezoelectric cell capable of producing an electrical output in response to a mechanical force upon the piezoelectric cell electrically connected to the electrically operable explosive device, a container of fire suppressant in contact with the structure, and a mechanical mechanism adjacent the piezoelectric cell for producing the mechanical force on the piezoelectric cell. The mechanical force produced by the mechanical mechanism is applied to the piezoelectric cell to produce the electrical output that actuates the electrically operable explosive device.
