security system. When properly locked, this door is able to defend against
unauthorized entry by brut force, penetration by bullets, or exposure to small
explosive devices.

Overview
The door is controlled and monitored by a FLIGHT DECK DOOR control panel
located on the aft aisle stand electronics panel. It is normally locked by two
independent electrical solenoids, either one of which will provide normal
locking functions. The door is electrically unlocked by the control panel or by
rotating the flight deck side doorknob in either direction. The cabin side door
handle is designed to limit pulling forces on the door to 250 lbs. maximum and
will not unlock the door.
The door is equipped with four blowout panels controlled by mechanical
pressure sensitive latches, which automatically open the panels during rapid
depressurization events. A red guarded emergency exit button, located adjacent
to the flight deck doorknob and two red panel retainers on the upper door panel
allow the blowout panels to serve as an emergency exit if the door becomes
jammed. There are instructional placards on the door for use of the emergency
exit system and resetting of the door after an emergency exit or depressurization
event. There is an independent MECHANICAL LOCK (pin) installed on the
flight deck side of the door for use during a system fault or for additional lock
redundancy during a significant security event. The door is equipped with a
viewing port, which allows a 150° view of the area immediately outside the
door.
There is a cabin side FLIGHT DECK DOOR EMERGENCY ENTRANCE
panel located by the right side of the door for emergency access to the flight
deck or for use as a “panic button” warning during significant security events.
A “DOOR, DOOR, DOOR” warning is emitted from dual speakers installed in
the flight deck overhead panel when this system is activated.
The door and integrated security system (including control panel, status lights,
and warning function) is powered from 28 Volt DC Bus 1 and 28 Volt DC Bus
2. Either bus will power the entire system. With loss of both of these buses
(such as standby electrical power operations or with the aircraft unpowered on
the ground) the door will be electrically unlocked and all system electrical
components including control panel, status lights, and warning functions will be
inoperative. Door system faults result in illumination of a red FLIGHT DECK DOOR
annunciator light located on the forward instrument panel and the red UNLKD
light on the door control panel.

Flight Deck Door Control Panel
< UNLOCK push button switch, status light, and coverguard.
Raise coverguard, push and hold down switch – electrically unlocks flight
deck door. Door will automatically electrically lock anytime switch is
released and door is in fully closed position.
UNLKD Light (red):
· Illuminates STEADY:
- When UNLOCK switch is held down, indicating door is unlocked
(normal condition). Also illuminates red FLIGHT DECK DOOR light
on forward instrument panel.
- When both solenoids have failed and door is unlocked (nonnormal
condition). Also illuminates red FLIGHT DECK DOOR light
on the forward instrument panel.
· Illuminates FLASHING:
- Indicates a fault in the door system or status lights and security of
the door is unknown (non-normal). Also illuminates red flashing
FLIGHT DECK DOOR light on forward instrument panel.
Note: With both UNLKD and FLIGHT DECK DOOR lights illuminated (nonnormal
condition), pushing the HARD LOCK switch extinguishes the
lights but does not activate HARD LOCK mode. This action does
not ensure door security, therefore the mechanical lock must
be engaged.
= Door OPEN Status Light
