The emergency access code is used to gain access to the flight deck in case of pilot
incapacitation. A flight deck chime and illumination of the amber AUTO UNLK
light indicates the correct emergency access code has been entered and the door is
programmed to unlock after a time delay. Selecting the DENY position on the
Door Lock selector denies entry and prevents further keypad entry for several
minutes. To allow entry, the selector is turned to the UNLKD position which
unlocks the door while held in that position. If the emergency access code is
entered and the pilot takes no action, the door unlocks after expiration of the time
delay. Before the door unlocks, the chime sounds continuously and the AUTO
UNLK light flashes.
By pressing "1" then "ENT" keys on the emergency access panel, the flight deck
chime will sound (if programmed).
The door incorporates two pressure sensors that unlock the decompression panels
in the event pressurization is lost. The decompression panels have manual release
pins. Pulling the pins frees the panels allowing egress in the event the door is
jammed.
