Which term best describes a controlled access feature with two doors that cannot be opened simultaneously?

• A. Sally port
• B. Routine mail
• C. Security equipment
• D. Report

Answer: (A)

The main idea here is an entry system that uses two doors that cannot be opened at the same time. This specific setup is called a sally port. It creates a secure checkpoint between areas, so staff can verify credentials, screen for contraband, and control movement before someone passes into a secure space. The design prevents someone from slipping through or tailgating, enhancing safety for both staff and inmates.

Rationale for the other terms: routine mail is unrelated to security doors and refers to mail handling; security equipment is a broad category of devices and doesn’t describe the two-door interlock feature; a report is a document, not a physical access mechanism.
