Abstract: A stand-alone, single-layer, auxiliary ballistic security barrier system configured to be installed over existing doors. The ballistic security barrier system provides protection against an active shooter with weapons, including handguns and high-powered rifles. The ballistic security barrier system includes a frame fixed to a wall with an anchor system and having structural tubing, mounting angle, and a locking system located inside the structural tubing. Further, the system includes a barrier pivotably attached to the frame and made out of material suitable to withstand impact from a high velocity rifle. The barrier is held in a first stowed position by a release apparatus, and in a second closed position by a lock.
