-the oxygen regulator 910WR1 and/or the oxygen regulator 910WR2 is/are defective.
An internal pressure sensor integrated in the oxygen regulators operates the 'SYS ON' indicator light 12WR. If the pressure in the system decreases less than 0.045 bar (0.65 psi) the 'SYS ON' indicator light 12WR goes off. If no masks are pulled, a max. time of 25 minutes is necessary to decrease the pressure of the system.
The 'REGUL SYS 1' and/or 'REGUL SYS 2' indicator light on the POXIP come(s) on if:
-the oxygen regulator 910WR1 and/or the oxygen regulator 910WR2 is/are defective.
OXYGEN STORAGE - DESCRIPTION AND OPERATION
__________________________________________
1. General_______
The passenger oxygen is supplied from chemical oxygen generators that are installed in emergency oxygen containers. The emergency oxygen containers are installed:
-above the passenger seats,
-at the cabin attendant stations,
-in the lavatories,
-at the cabin attendant working areas.

A. Emergency Oxygen Container
(1) Chemical Oxygen Generator The chemical oxygen generator is a sodium-chlorate core installed in a stainless-steel housing. A thermal insulating material is used between the core and the housing. The actuator of the chemical generator is a spring-loaded striker and a percussion cap installed at one end of the housing. A release pin holds the striker away from the cap. A lanyard connects the release pin to the oxygen mask. A filter assembly is installed in the outlet end of the housing to prevent the contamination of the oxygen supply. A flexible hose connects the oxygen mask to the outlet manifold and the outlet valve supplies oxygen to the oxygen mask. The outlet is installed on the housing. A relief valve is installed at the outlet end of the housing. This will prevent a high-pressure build-up, if a failure of the outlet valve occurs. An indicator on the housing will change color (from yellow to black) when the chemical oxygen generator is used and the generator is not more usable.
