Standard mantraps and sally ports provide a controlled passageway where only one door in the passageway can be opened at a time. A mantrap or sally port may contain 2 or more doors. A mantrap or sally port may be connected to an overhead door. Securitech’s basic two door Entry & Exit Control Systems expand on the basic mantrap or sally port system. By using dual-locking technology, Securitech can create systems which provide operational security and meet special operational and life-safety needs. Securitech’s Custom 2, 3, and 4 door Entry & Exit Control Systems start with a blank piece of paper; the end-user lists all of their requirements and Securitech creates the system which fulfills those needs.
