(3) Door and Latch Assembly The electrical latch assembly holds the door of the emergency oxygen container closed. Spring pressure will open the door when the electrical latch assembly is electrically released. A door stop is installed in the emergency oxygen container to let you do an inspection and a test of the emergency oxygen container. The door stop is turned through 90 degrees to let the door open a few degrees. The oxygen masks will not fall out. To open the door manually, you can release the electrical latch assembly with a manual release tool.

When the door latch gets an electrical signal from the oxygen control and actuation circuit (REF 35-23-00) the doors of the emergency oxygen containers will open. The oxygen masks will fall out and hang on lanyards near to the person who will use it. The person pulls the oxygen mask (in the lavatories there is a red pull flag attached to the lanyard) to their face. This action makes the lanyard pull a release pin from the striker assembly of the chemical oxygen generator. The striker assembly hits the percussion cap and starts the supply of oxygen. The oxygen will flow through the flexible supply hoses to the oxygen mask. A flow indicator (located in the supply hose) will show a green color when the oxygen flows through it. The chemical oxygen generators will supply a flow of low pressure oxygen for a minimum time of 15 minutes.

(Ref. Fig. 004) To make sure that the doors of the emergency oxygen containers open, you must do a periodic ground test. To check that the electrical latches operate correctly, press the MASK MAN ON pushbutton switch 14WR (REF 35-23-00). The oxygen masks do not fall out, if you push the left hand side of the test lever on the door assembly of the emergency containers. Push the test lever until the over-center spring keeps the lever at 90 degrees to the door surface. This will let the doors open a few degrees when the ground test is done. After the test, close the doors and push the test lever back to the initial position.

To make sure that the doors of the emergency oxygen containers will open, a periodic ground test is done. To check that the electrical latches operate correctly, you press the MASK MAN ON pushbutton switch 14WR (REF 35-23-00). So that the oxygen masks do not fall out, the door stops on the emergency containers are pulled down with the fingers and turned 90 degrees to the test position. This will let the doors open a few degrees when the ground test is carried out. After the test, the doors have to be closed and the door stops turned 90 degrees to the normal position.
