O OXY high pressure indication
~
~
Green : When pressure is > 400 psi.
Amber : When pressure is < 400 psi.
An amber half frame appears when oxygen pressure is < 1500 psi.
In this case, the flight crew must check that the remaining quantity is not
below the minimum (refer to OPERATING LIMITATIONS, 3.01.35).
REGUL LO PR indication
Appears amber if oxygen pressure on the low-pressure circuit is low (50 psi)
OXY indication
Normally green.
Becomes amber when :
- Pressure goes below 400 psi.
- Low oxygen pressure is detected.
- The OXYGEN CREW SUPPLY pushbutton switch on overhead panel is OFE

┗━━━━━━━━━━━━━━━━┻━━━━━━━━━━━━━━━┻━━━━━┻━━━━━┛
The cabin's fixed oxygen system supplies oxygen to the occupants, in case of cabin
depressurization.
Chemical generators produce the oxygen. Each generator feeds a group of 2, 3, or 4 masks.
Generators and masks are in containers above the passenger seats, in the lavatories, in
each galley (<~), and at each cabin crew station.
OPERATION
Each container has an electrical latching mechanism that opens automatically to allow the
masks to drop, if the cabin pressure altitude exceeds 14000 feet (+ 0, - 500 feet). The
flight crew can override the automatic control.
When the masks are released, the passenger address system automatically broadcasts
prerecorded instructions for their use.
The generation of oxygen begins when the passenger pulls the mask towards the
passenger seat. The chemical reaction used for oxygen generation creates heat. Therefore,
the smell of burning or smoke, and cabin temperature increase, may be associated with the
normal operation of the oxygen generators.The mask receives pure oxygen under positive
pressure for about 15 minutes, until the generator is exhausted.
A reset is available for the rearming of the system after the masks are restowed. A manual
release tool allows crewmembers to manually open the doors in case of electrical failure.
