Vault door

Vault door is a term usually used to refer to the gear-shaped entrance to a Vault-Tec Vault. It may also refer to the standardized door mechanisms within.
== Entrance variants ==
==Interior variants==
===Standard door===
A typical door used in the Vaults is composed of two pieces that connect and seal (with the use of special interlocking cones) when the door closes. An emergency override handle is placed above the connection seam. Each door is operated by hydraulic motors that affect 3300 lbs of pressure when operating the door.
The doors are designed with three safety features. The first is a caution zone marked by yellow lines on the floor. The second is an automated system that reverses the door if it detects an obstruction, and attempts at closing the door a few moments later. If the obstruction remains under the door, it will continue repeating this motion until powered off or the door finally closes. The final feature is a power box next to the door, which can be used to shut off electricity to the bulkhead and seal it. Under normal circumstances, the lamps on the power box are green. If the power to the door is cut using the switch, they glow red.
===Interior doors===
The Vault door is a type of electro-mechanical door used in the Vault-Tec Vaults for creating physical barriers between corridors, rooms, and stairways. The hatch is a heavy steel door, of either one or two pieces, supported in a heavy steel frame built into a wall and powered by concealed powerful hydraulic motors.
===Security door===
This model is identical in function and safety features to the door above, except there is a centrally painted white vertical band with a stop sign and the words "No Access - Authorized Personnel Only". There are downward pointing chevrons above and below the text.
=== Residential door ===
Vertically sectioned white doors which collapse upward when activated. Some are thin veneers, others are reinforced.
===Maintenance hatch===
This is a one-piece hatch. Hydraulic motors swing it 90 degrees on a hinge when opening. On one side of the hatch, there are two circular indicators. When the hatch is closed, both indicators display diagonal red lines on a white background. As the hatch is opening, the indicators display OPEN in red text on a white background, while the other shows STAND BACK in red text on a black background.
== Notes ==
* In Fallout 3, NPCs can activate the large sealed Vault entrances as if they were regular doors.
== Behind the scenes ==
* The engine of Fallout 76 treats Vault entrances as doors, even when they only transfer between loading zones, or do not function at all. Consequently they can be physically passed through under certain unintended circumstances, though there is nothing behind them but solid rock.
