Abstract:
1. A fiber-optic based fire extinguishing system utilizing a fire suppressant controller comprising: at least one light emitting diode (LED) for providing a source of light; at least one sensor body formed of a closed continuous loop of unshielded fiber optic strand; at least one photo transistor for receiving the light through the at least one sensor body; a first coupler assembly formed between the at least one LED and the fiber optic strand for efficiently transferring light from the LED into the fiber optic strand; a second coupler assembly formed between the at least one photo transistor and the optic strand for efficiently transferring light from the optic strand to the at least one photo transistor; and wherein a spring load firing valve is triggered when the at least one photo transistor no longer receives light through the at least one sensor body.
