A mantrap is an access control tool designed and restricted to a physical space, which is separated from the adjoining spaces (rooms) by two doors, usually an exit and an entry door that cannot be unlocked at the same time. Mantraps are like a double-door checking system that use either airlock technology or interlocking doors.
Mantraps work by using an interdependent locking/unlocking methodology, which grants access to the second door only when the first door has been properly locked. The person trapped in a mantrap must wait for the first door to lock and provide additional credentials, such as passcodes or biometric authentication to be able to go through the second door.
Today's simplified automatic mantrap rooms enable access with access cards, key fobs and mobile phones. Since mantraps prevent two persons (unless authorized) to be in the same room, they can be used for shared spaces in hospitals, dormitories and boarding rooms or anywhere else where people have some need for privacy.
Although most common mantraps work with a system of two interlocked doors, there are solutions that can be implemented on three or more doors, including varied authentication systems. “Real” mantraps typically have two locked doors. Some interlocked mantraps, such as those used at bank entrances, are unlocked to begin with, and only lock when one of the doors is open.
