A lock system includes an active panel center gearbox. The active panel center gearbox includes a deadbolt, a deadbolt drive to extend or retract the deadbolt, an upper drive assembly, a lower drive assembly, a latch bolt, a handle assembly to retract the latch bolt and to extend or retract the lower and the upper driver assemblies, a reverse action rocker coupling the lower and the upper drive assemblies so they move in different directions, a mishandling bolt, and a mishandling plate. When the mishandling bolt extends, it lowers the mishandling plate. When the mishandling plate lowers, it engages the deadbolt to prevent the deadbolt from extending, it engages the handle assembly to prevent the lower drive assembly from extending, and it engages the reverse action rocker to prevent the upper drive assembly from extending. |
