Abstract
A door security assembly for blockading a door in a lockdown situation includes a blockade device. An element of the blockade device insertable into a gap defined by a door and a crash bar that is engaged to the door. Each of a pair of fasteners engaged to the blockade device is selectively engageable the crash bar, so that the blockade device is reversibly engaged to the crash bar with the element positioned in the gap. The blockade device prevents actuation of the crash bar so that the door cannot be opened. The fasteners are positioned so that two hands are required to simultaneously disengage the fasteners from the crash bar to enable disengagement of the blockade device from the crash bar.
