Claim 14:
15. A motorized latch retraction system for transitioning a latch of an exit device from a latched position to 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 a first position corresponding to the latched position of the latch and a second position corresponding to the unlatched position of the latch;
a motor assembly including:
a floating motor configured for movement relative to the guide structure;
an actuator operably engaged with and extending linearly from the floating motor and actuatable by the motor, the actuator operably coupled to the retraction arm to actuate the retraction arm and the latch between the latched position and the unlatched position; and

a lock indicator having a visible lock indicator and a visible unlock indicator, the lock indicator operably coupled to the retraction arm such that actuation of the retraction arm actuates the lock indicator, actuation of the retraction arm and the latch to the latched position corresponding to actuation of the lock indicator to a lock indicator position in which the visible lock indicator is viewable and the visible unlock indicator is obscured from view, actuation of the retraction arm and the latch to the unlatched position corresponding to actuation of the lock indicator to an unlock indicator position in which the visible unlock indicator is viewable and the visible lock indicator is obscured from view.
