What type of doors does KA-1 NOT open?

The KA-1 system is typically designed to control access to various secure locations within a correctional facility. It is specifically programmed to manage doors that are related to inmate movement and security operations. The correct choice reflects the premise that the KA-1 system does not grant access to non-secure or less critical areas like a unit officer restroom.

Unit officer restrooms are generally meant for staff only and do not require the enhanced security measures that KA-1 provides for areas involving inmates, such as the Rec Yard door, Attorney Visitation Room, or Food Flaps. These locations are critical for inmate movement, legal consultations, and feeding, hence they are monitored by the KA-1 system to ensure security protocols are maintained.

In essence, the reason for this choice lies in the nature of the access control—areas that are essential for inmate interaction and procedures are covered, while staff-only facilities are not within the scope of KA-1's functions.
