Insulated Door

The Security Door is a special access building used in ruined structures and bioscan checkpoints. It is associated with duplicant screening, and the scan must be completed from the correct side of the door. If duplicants are not queuing for the bioscan task, it usually means they need to approach from the other side, often by digging around the door to create access.

Ruins can also contain an interior variant of the Security Door, separating multiple rooms within the same structure. This variant is teal-colored and does not require a bioscan. Functionally, it behaves like a Mechanized Airlock that does not need power: its access controls always allow all duplicants, and those permissions cannot be changed.

• Security Doors appear to work only one way for bioscan access.
• The interior variant is found in ruins and is used to divide rooms.
• The interior variant does not require power.
• The interior variant always permits all duplicants and cannot be reconfigured.
• Because the bioscan must be approached correctly, digging an alternate path is often the simplest way to make the task available.
