Claim 8:
9. A motorized latch retraction system with mechanical dogging for retaining a latch of an exit device in an unlatched position, the motorized latch retraction system comprising:
a retraction assembly including a guide structure configured to be coupled to the exit device, the retraction assembly having a retraction arm operably coupled to the latch of the exit device, and the retraction arm moveable relative to the guide structure between an extended position corresponding to the latched position of the latch and a retracted position corresponding to the unlatched position of the latch;
a floating motor configured for movement relative to the guide structure, the floating motor operably coupled to the retraction arm, the floating motor including an actuation member extending linearly therefrom, the actuation member operably coupled to the retraction arm and operable to transition the retraction arm from the extended position to the retracted position; and
a mechanical dogging member moveably coupled to the retraction arm, the dogging member operable to be positioned in an active position and a passive position, the dogging member limiting movement of the retraction arm relative to the retraction guide when in the active position.
