A slide is movably received in the housing and includes a drive bar connection element, wherein when the slide is in an unlocked position, the drive bar connection element is located in a path of travel of the deadbolt, and wherein when the slide is in a locked position, the drive bar connection element is located outside the path of travel of the deadbolt. At least one drive bar at least partially received in the housing and is connected to the drive bar connection element. The drive bar is actuated by an actuator located remote from the housing. A blocking element located within the housing, wherein the blocking element prevents movement of the slide from the locked position to the unlocked position. ## Claims ### Claim 1 A lock mechanism for an inactive door, the lock mechanism comprising: a housing configured to receive a locking element from an active door lock; a slide movably received in the housing and comprising a drive bar connection element, wherein when the slide is in an unlocked position, the drive bar connection element is located in a path of travel of the locking element, and wherein when the slide is in a locked position, the drive bar connection element is located outside the path of travel of the locking element; at least one drive bar at least partially received in the housing, wherein the drive bar is connected to the drive bar connection element and wherein the drive bar is actuated by an actuator located remote from the housing; and a blocking element located within the housing, wherein the blocking element prevents movement of the slide from the locked position to the unlocked position. ### Claim 2 (depends on 1) The lock mechanism of claim 1, wherein the blocking element is pivotably connected to the housing and comprises a dog, wherein when the blocking element is in a slide blocked position, the dog is located within a path of travel of the slide. ### Claim 3 (depends on 2) The lock mechanism of claim 2, wherein the blocking element comprises an actuator adapted to be actuated by at least one of a thumbturn located external to the housing and a key cylinder located external to the housing. ### Claim 4 (depends on 2) The lock mechanism of claim 2, wherein the blocking element is biased into both of the slide blocked position and a slide unblocked position. ### Claim 5 (depends on 4) The lock mechanism of claim 4, wherein the blocking element is adapted to be rotated from the slide unblocked position to the slide blocked position only when the slide is in the locked position. ### Claim 6 (depends on 1) The lock mechanism of claim 1, wherein the blocking element is pivotably connected to the slide and comprises a projection, wherein when in a slide blocked position, the projection is positioned such that a pin extends into a path of vertical travel of the projection. ### Claim 7 (depends on 6) The lock mechanism of claim 6, wherein the blocking element is biased into a slide unblocked position, wherein the pin does not extend into a path of vertical travel of the projection. ### Claim 8 (depends on 6) The lock mechanism of claim 6, wherein the blocking element is adapted for movement from a slide unblocked position to the slide blocked position due to contact with the locking element extending into the housing. ### Claim 9 (depends on 1) The lock mechanism of claim 1, wherein the blocking element comprises an actuator pivotably connected to the housing. ### Claim 10 (depends on 1) The lock mechanism of claim 1, wherein the slide is adapted to move vertically due to actuation of an element located discrete from housing. ### Claim 11 (depends on 1) The lock mechanism of claim 1, further comprising a drive bar actuation mechanism for moving the slide between the unlocked position and the locked position. ### Claim 12 (depends on 10) The lock mechanism of claim 10, wherein the drive bar actuation mechanism is located in a drive bar actuation mechanism housing discrete from the housing. ### Claim 13 (depends on 11) The lock mechanism of claim 11, wherein the drive bar actuation mechanism is operated by pivotal movement of a handle located on the drive bar actuation mechanism housing. ### Claim 14 A lock mechanism for an inactive door, the lock mechanism comprising: a housing configured to receive a deadbolt from an active door lock; and a selectively actuable blocking element, wherein when the blocking element is in an unlocked position, the blocking element is located in a path of travel of the deadbolt, and wherein when the blocking element is in a locked position, the blocking element is located outside the path of travel of the deadbolt. ### Claim 15 (depends on 14) The lock mechanism of claim 14, further comprising an actuator located within the housing, wherein the actuator is selectively actuable to prevent movement of the blocking element from the locked position to the unlocked position. ### Claim 16 (depends on 15) The lock mechanism of claim 15, wherein when the deadbolt is received in the housing, the blocking element is prevented from moving to the unlocked position. ### Claim 17 A lock mechanism for an inactive door, the lock mechanism comprising: a slide for selectively moving a drive bar between a locked position and an unlocked position; a first blocking element for preventing movement of the slide from the locked position to the unlocked position, wherein the first blocking element prevents movement of the slide when contacted by a deadbolt inserted into the locking mechanism; and a second blocking element for selectively preventing movement of the slide from the locked position to the unlocked position. ### Claim 18 (depends on 17) The lock mechanism of claim 17, wherein the first blocking element is pivotably connected to the slide. ### Claim 19 (depends on 18) The lock mechanism of claim 18, wherein the first blocking element prevents movement of the slide due to contact with between the first blocking element and a projection extending from a housing of the lock mechanism. ### Claim 20 (depends on 17) The lock mechanism of claim 17, wherein the second blocking element prevents movement of the slide due to positioning a dog in a path of travel of the slide.
