Abstract: A dogging mechanism for an exit device may include a camming element that is configured to rotate between an undogged position and a dogged position. The dogging mechanism may include a first linkage operatively coupled to a latch of the exit device and a second linkage operatively coupled to the camming element. The first linkage may be fixed to the camming element such that movement of the camming element between the undogged position and the dogged position moves the latch between a latched position and an unlatched position, respectively. The camming element may include at least one slot that is at least partially curved, and the slot may receive a pin of the second linkage such that the slot is movable relative to the second linkage to move the camming element between the undogged and dogged positions.

Abstract: A pull handle may include a chassis, a latch disposed at least partially in the chassis, a thumb turn, and a dogging fastener movably disposed on the thumb turn. The thumb turn may be rotatable between a locking position and an unlocking position, where the thumb turn is coupled to the latch such that when the thumb turn is in the locking position the latch is in an extended position and when the thumb turn is in the unlocking position the latch is in a retracted position. The dogging fastener may be configured to move between a dogging position and an undogging position, where in the dogging position the dogging fastener engages the chassis to inhibit rotation of the thumb turn.
