• a first release mechanism located on an interior side of the door, the first release mechanism including a release element operatively attached to the rotatable member of the latching assembly and movable between a rest position and a release position, movement of the release element from the rest position to the release position moving the latch from the latching position to the unlatching position;
• and
• a second release mechanism located on the interior side of the door, the second release mechanism including a release element attached to the bar for moving the bar from the first position to the second position;
• and
• wherein the first release mechanism includes an extending element attached to the rotatable member of the latching assembly, and wherein the rotatable member of the latching assembly includes a plate, a first end of the latch being pivotally attached to the plate, the rotatable member defining an opening with a camming profile for selectively rotating with the key cylinder when the plate rotates;
• and
• wherein the first release mechanism further includes a cover with at least one arcuate guide slot adjacent the rotatable member, the arcuate guide slot directing and defining a rotational extent of movement of the extending element.
