When the deadbolt system is in a cross position, what does it signify?

When the deadbolt system is in a cross position, it signifies that the lock is in a secure state where the key is operable. This means that you can use a key to operate the lock, allowing for standard locking and unlocking procedures. The cross position typically indicates that the deadbolt is engaged and secured, ensuring that the door is firmly locked, and at the same time, it suggests that the mechanism can be manipulated with the appropriate key.

In contrast, the other options represent different scenarios: "Unlocked" would indicate a position potentially vertical or horizontal without the cross, "Locked - key inoperable" would suggest that the lock cannot be operated with a key, perhaps due to being thrown into a dead state or malfunctioning, and "Requires special access" implies that an additional method or unique key is necessary to engage or disengage the lock, which does not align with the standard functioning of a deadbolt in the cross position.
