A fire suppression system adapted for use in a lavatory of an aircraft. The system includes a supply coupled to one or more fluid discharge nozzles via one or more fluid flow lines. A pressure source in communication with the fluid flow lines provides pressure to assist in supplying a pressurized flow of fluid through the flow line(s) to the nozzles(s). Furthermore, the system is capable of using the potable water supply of the aircraft or it can be self-contained with its own water supply reservoir. If self-contained, the system includes a pressurized fluid source to assist in supplying water to the discharge nozzle(s).

What is claimed is: 1. A fire suppression system operable to extinguish a fire within a lavatory of an aircraft comprising: a primary reservoir and a secondary reservoir for holding a supply of fire extinguishing medium therein, wherein each of said primary reservoir and said secondary reservoir contain an independent quantity of said fire extinguishing medium, and wherein said fire extinguishing medium contained by said primary reservoir is evacuated prior to releasing said quantity of fire extinguishing medium from said secondary reservoir; at least one nozzle for spraying said fire extinguishing medium over a predetermined area within said lavatory; at least one supply line for supplying said fire extinguishing medium from at least one of the primary reservoir or the secondary reservoir to the nozzle; a valve, positionable between a closed position and an open position and operably associated with the supply line, said valve being positionable in said open position when a fire occurs within said lavatory; a signaling system for providing a signal to an individual to indicate that said fire extinguishing medium from at least one of the primary reservoir or the secondary reservoir is being communicated through said supply line to said nozzle; and wherein said nozzle and said valve comprise an integrally formed component, and wherein said valve is closed when a material having a low melting point is affixed to said nozzle, and holding said nozzle closed, when said valve is in said closed position. 2. A fire suppression system operable to extinguish a fire within a lavatory of an aircraft comprising: a primary reservoir and a secondary reservoir for holding a supply of fire extinguishing medium therein, wherein each of said primary reservoir and said secondary reservoir contain an independent quantity of said fire extinguishing medium, and wherein said fire extinguishing medium contained by said primary reservoir is evacuated prior to releasing said quantity of fire extinguishing medium from said secondary reservoir; at least one nozzle for spraying said fire extinguishing medium over a predetermined area within said lavatory; at least one supply line for supplying said fire extinguishing medium from at least one of the primary reservoir or the secondary reservoir to the nozzle; a valve, positionable between a closed position and an open position and operably associated with the supply line, said valve being positionable in said open position when a fire occurs within said lavatory; a signaling system for providing a signal to an individual to indicate that said fire extinguishing medium from at least one of the primary reservoir or the secondary reservoir is being communicated through said supply line to said nozzle; and an actuation sensor, wherein said actuation sensor indicates when fluid is communicated through said fluid supply line and out of said nozzle. 3. A fire suppression system adapted for use with a lavatory of an aircraft comprising: a primary fluid supply dedicated to fire suppression and a secondary fluid supply consisting of a potable water supply of the aircraft, wherein a fluid from said primary fluid supply is evacuated prior to a fluid from said secondary fluid supply is released therefrom; a fluid communication line, wherein a fluid from at least one of said primary fluid supply or said secondary fluid supply is operable to move though said fluid communication line; a nozzle operably interconnected with said fluid communication line; a valve operatively associated with said nozzle and having a closed position and an open position, wherein when said valve is in said open position when a fire is sensed to allow fluid to be evacuated from at least one of said primary fluid supply or said secondary fluid supply through said nozzle; and a signal system operable to signal a user that the fluid is being communicated through fluid communication line. 4. The fire suppression system of claim 3, further comprising: a pressurized fluid source separate from either of said primary fluid supply or said secondary fluid supply operable to pressurize said fluid to force said fluid through said communication line when said valve is opened. 5. The fire suppression system of claim 4, further comprising: a gage in communication with said pressurized fluid source to indicate a pressure within said pressurized fluid source. 6. The fire suppression system of claim 3, wherein said valve comprises a eutectic valve operable to assume an open position in response to sensing a fire, and operable in said open position to permit said fluid to be discharged through said nozzle. 7. The fire suppression system of claim 3, further comprising: a controller; and a sensor operable to sense the presence of a fire, wherein said sensor delivers a signal to said controller when the fire is detected. 8. The fire suppression system of claim 7, wherein the valve comprises a solenoid valve positionable between said closed and said open positions by said controller. 9. The fire suppression system of claim 3, further comprising: an actuation sensor operable to indicate when said fluid is communicated through said fluid communication lines. 10. The fire suppression system of claim 3, wherein evacuating the secondary supply occurs only after the first supply is substantially exhausted and the fire remains unsuppressed. 11. A fire suppression system operable to extinguish a fire within a lavatory of an aircraft comprising: a reservoir for holding a supply of fire extinguishing medium therein; at least one nozzle for spraying said fire extinguishing medium over a predetermined area within said lavatory; at least one supply line for supplying said fire extinguishing medium from the reservoir to the nozzle; a valve, positionable between a closed position and an open position and operably associated with the supply line, said valve being positionable in said open position when a fire occurs within said lavatory; a pressure sensor interconnected with said at least one supply line operable to provide a signal to a monitoring system to indicate that said fire extinguishing medium from said reservoir has pressurized said supply line to said nozzle; a pressurized fluid source, wherein said pressurized fluid source pressurizes said supply line when said valve is in said open position; a controller; and at least one sensor adapted to sense the presence of a fire, wherein said sensor provides a signal to said controller when the fire is detected; wherein the signal from the at least one sensor is provided to the controller which is operable to provide a signal to the pressurized fluid source to pressurize at least one of the reservoir or the supply line to move the fire extinguishing medium through the supply line and out of the nozzle to within the lavatory. 12. The fire suppression system of claim 11, wherein said reservoir includes a primary reservoir and a secondary reservoir with each said reservoir containing an independent quantity of said fire extinguishing medium, and wherein said fire extinguishing medium contained by said primary reservoir is evacuated prior to releasing said quantity of fire extinguishing medium from said secondary reservoir. 13. The fire suppression system of claim 12, wherein the primary reservoir is substantially only a fire extinguishing medium reservoir and the secondary reservoir consists of an airplane potable water reservoir substantially separate from the primary reservoir. 14. The fire suppression system of claim 11, wherein said nozzle and said valve comprise a single component, and wherein said valve is closed when a material having a low melting point is affixed to said nozzle, and holding said nozzle closed, when said valve is in said closed position. 15. The fire suppression system of claim 11, further comprising an actuation sensor, wherein said actuation sensor indicates when fluid is communicated through said fluid supply line and out of said nozzle. 16. The fire suppression system of claim 11, further comprising: a lavatory of an aircraft; wherein the monitoring system includes a cabin attendant alert system; wherein the signal to the cabin attendant alert system is operable to provide a signal to a cabin attendant to indicate that a fire has been sensed. 17.
