A "man-sized opening" is at least how many square inches?

A "man-sized opening" is defined as an opening that measures at least 96 square inches. This standard is significant in the context of burglar alarms and security systems because it helps in the identification of potential access points for a person. The concept is utilized to assess vulnerabilities in security.

96 square inches equates to an opening that measures 12 inches by 8 inches or any combination that results in the same area. This size is considered large enough to allow a person to pass through, which can be a critical factor for assessing risk in both residential and commercial security planning.

The other options do not meet the commonly accepted definition of a man-sized opening, making 96 square inches the correct choice, as it aligns with industry standards regarding the size of openings where a person could potentially gain unauthorized access.
