On a recent field trip with the members of Allegion’s Early Careers Program, I saw a fantastic example of a secure entry vestibule in a high school.  After entering the vestibule from the exterior, visitors must check in with Security before being allowed to proceed through the interior doors into the school (or not).  Although this type of vestibule is sometimes incorrectly called a “man-trap”, it does not function like a sallyport or interlock because it allows free egress through the exterior doors at all times.  These vestibules play a very important role in limiting unauthorized access to school buildings.
