The flight crew oxygen system supplies oxygen to the flight crew. It is used if there is a loss of cabin pressurization or smoke or dangerous gases in the cockpit. The oxygen is supplied by a high pressure oxygen cylinder to quick donning masks in the cockpit. Passenger Oxygen System The passenger and cabin attendant oxygen system is supplied by chemical oxygen generator units located in the cabin, cabin attendant stations, lavatories and galleys. Two types of chemical generators are offered which provide oxygen for 15 minutes or 22 minutes. Portable Oxygen System The portable oxygen system supplies oxygen to the passengers, the cabin attendants and the flight crew in an emergency and for first aid treatment. The smoke hood system provides breathing means and eye protection for the flight crew members and cabin attendants. It permits them to move freely to extinguish a fire. The high pressure portable cylinder with continuous flow type masks supplies first aid oxygen for the passengers.

This cylinder can be isolated for maintenance by a manual ON/OFF valve. A direct-reading pressure gage gives an indication of the cylinder pressure, independent of the open or closed position of the manual valve. The cylinder is installed in a cradle with two quick-release clamps in the L/H avionics compartment. A pressure regulator transmitter assembly is directly connected to the cylinder. It consists of a high-pressure stage with an integrated pressure transducer for ECAM indication and a low pressure stage. The pressure regulator regulates the low pressure at 4.48 to 6.48 bar (65 to 94 psig). A supply valve opens or closes the crew oxygen supply. The CREW SUPPLY P/B on the oxygen panel controls the supply valve. High pressure and low pressure protection is achieved by safety devices consisting of a high-pressure safety outlet and a low pressure safety outlet. The high-pressure safety outlet is a frangible disk type. The low pressure safety outlet is a pressure relief valve. An overboard green discharge indicator is connected to the high pressure safety outlet and to the low pressure safety outlet. In case of over pressure, the green disk blows out and a yellow indicator is displayed showing that the cylinder has discharged or the pressure relief valve has opened. A pressure switch and a test port are connected to the distribution manifold. The pressure switch operates when the oxygen supply pressure decreases to 3.45 plus or minus 0.35 bar (50 plus or minus 5 psig) and transmits a warning signal REGUL LO PR to the ECAM/DOOR/OXY page. On the lower ECAM DU, on the DOOR/OXY page, the oxygen pressure in the cylinder is indicated as follows: (a) 0 to 27.5 bar (0 to 400 psig) in amber. (b) 27.5 to 127.5 (400 to 1850 psig) in green. (c) An amber half frame appears when the oxygen pressure is lower than 1500 psig. If the oxygen pressure drops below the minimum operating pressure of 3.45 plus or minus 0.35 bar (50 plus or minus 5 psig), the indication REGUL LO PR is shown amber on the DOOR/OXY page. The mask assembly and the stowage box are installed adjacent to each crew member seat. The stowage box contains the mask, when the mask is pulled out of the box a supply valve installed in the stowage box will open and let oxygen flow to the mask. To use the mask, squeeze the red clips. This will inflate the mask harness. Bring the mask in position and release the red clips. Releasing the red clips will stop oxygen flow to the harness and vent the oxygen remaining in the harness to the atmosphere. Now the mask is ready for use.

A taped message is transmitted on the passenger address system. The passenger SYStem ON indicator light comes on white when the passenger oxygen system is electrically supplied. A reset is available to rearm the electrical system after mask re stowage. A release tool allows manual opening of the door in case of failure of the container door opening system. When the TiMeR RESET pushbutton is pressed, the ON white light of the TMR RESET pushbutton comes on. The indicator light SYS ON goes off and the taped announcement stops. On ground, used chemical oxygen units must be replaced and all masks re stowed. The system is reset by momentarily pressing the TMR RESET pushbutton on the maintenance panel. Manually operated doors stops are fitted on the container doors to allow an operational test of the mask release system. When set to test position the door stops will prevent doors from fully opening and masks from dropping out of the container.
