The present invention is directed to an apparatus for supplying gas at a first pressure and at a second pressure. The apparatus includes a gas generating system having a gas generating system outlet. A flow switch is in communication with the gas generating system outlet and has an outlet thereof forming a gas outlet at the first pressure. A pressure regulator is in communication with the gas generating system outlet for regulating gas flowing to the gas outlet at the first pressure. A solenoid valve is electrically controlled by the flow switch and is in communication with the gas generating system outlet and has a solenoid valve outlet. A pressure intensifier is in communication with the solenoid valve for raising the pressure of the gas generated by the gas generating system for output to an outlet at a second pressure.
