1. A system, comprising:
a mortise chassis configured to be mounted within a mortise cutout of a door, the mortise chassis comprising:
a mortise casing sized and shaped to be mounted within the mortise cutout of the door;
an actuation assembly movably mounted to the mortise casing;
a first transmission movably mounted in the mortise casing and operably coupled with the actuation assembly, wherein the actuation assembly is operable to drive the first transmission from a first deactuated position to a first actuated position;
a second transmission movably mounted in the mortise casing and operably coupled with the actuation assembly, wherein the actuation assembly is operable to drive the second transmission from a second deactuated position to a second actuated position;
a hold-open link connected between the first transmission and the second transmission, the hold-open link movable between a holding position and a release position;
an upper remote latch device positioned above the mortise chassis and connected with the first transmission via a first cable; and
a lower remote latch device positioned below the mortise chassis and connected with the second transmission via a second cable;
wherein in the holding position, the hold-open link is configured to retain the second transmission in the second actuated position while permitting movement of the first transmission from the first actuated position toward the first deactuated position;
wherein the first transmission is configured to move the hold-open link from the holding position to the releasing position as the first transmission moves from the first actuated position toward the first deactuated position; and
wherein in the release position, the hold-open link is configured to permit movement of the second transmission from the second actuated position to the second deactuated position.
