Describe a mantrap.

What will be an ideal response?


A mantrap is designed to separate a nonsecured area from a secured area. A mantrap device monitors and controls two interlocking doors to a small room (a vestibule). When in operation, only one door is able to be open at any time. Mantraps are used at high-security areas where only authorized persons are allowed to enter, such as sensitive data-processing rooms, cash-handling areas, and research laboratories.
