(30) The door locks using one vertical movement push down on the door lock rod 300 until it seats in the floor insert 700. Unlocking is accomplished using any one of three methods. Method 1—by rotating the door handle in either direction disengages the lock rod from the floor insert. In this method, the wire 600 is wound around the knob/handle such that the wire 600 is pulled upward when the knob is turned from the inside of the room. As the wire 600 moves upward, the tip 404 of the pivot lever 400 rotates downwardly on pin 202 such that the tip 404 becomes disengaged from the grooves 309 of the door lock rod 300. The coil spring 302 can then resiliently urge the rod 300 upward by pushing on the rod bushing 306.

(31) Method 2—Pushing the release button 500 on the bottom of the box disengages the lock rod 300 from the floor insert 700. As the release button 500 in pushed upward, the distal tip 502 pushes upward on the end 402 of the lever 400. In one motion, the tip 404 of the pivot lever 400 rotates downwardly on pin 202 such that the tip 404 becomes disengaged from the grooves 309 of the door lock rod 300. The coil spring 302 can then resiliently urge the rod 300 upward by pushing on the rod bushing 306.

(32) Method 3—Use two protrusions on the key to remove the security cover that hides the key access port. Then, insert and turn the EMS key 900 from the outside (hallway side) to disengage the lock rod 300 from the floor insert 700. The port 802 has an access port through the door to accommodate the key 900 accessible from an exterior side. As the key 900 is rotated, the cam end 902 pushes upward on the end 402 of the lever 400. In one motion, the tip 404 of the pivot lever 400 rotates downwardly on pin 202 such that the tip 404 becomes disengaged from the grooves 309 of the door lock rod 300. The coil spring 302 can then resiliently urge the rod 300 upward by pushing on the rod bushing 306.

(33) In some constructions for use in schools, a lock is installed on the classroom side of the door lock system. The lock allows the teacher to prevent students from engaging the system and potentially locking the teacher out of the room. In one construction, all locks in a school can be keyed alike thereby allowing use in any classroom. In the event of a situation requiring a lock down of the room, the teacher may use the key to unlock the door lock system and then depresses the locking rod 300 thereby engaging the system 100 and then following Established Security Protocol. In the event of an emergency exit by the rooms occupants, a normal depressing of the door handle either up or down disengages the lock bar 300 for immediate egress.

(34) FIGS. 16-18 illustrates a schematic diagram an alternative barrier locking system 1000 in which certain aspects of the present disclosure may be implemented. The barrier lock bar 1300 has a cam key assembly installed to allow the barrier lock bar 1300 to be pulled up and rotated to insure the engaged position. The barrier lock bar 1300 is pulled up and turned to engaged position and reversed to return to down position flush with base plate resulting in a dormant position, the guide pin provides the barrier lock with limited movements within the casing 1200. The barrier lock bar 1300 has indented grooves vertical and lateral 1309 that determines the length and depth of movement up-and-down and the position at which the barrier lock bar 1300 stays in place once turned to the right.
