An exit device including an intermediate transmission assembly transmitting the translation of an input into a rotational vertical rod output is disclosed. An upper door latch receiving a rotational vertical rod input to actuate an upper door latch from a latched position to an unlatched position is further disclosed. A lower latch receiving a rotational vertical rod input to actuate a lower latch from a latched position to an unlatched position is additionally disclosed.

Exit device assembly

A lock core includes a shell, a plug within and rotatable relative to the shell between a first position and a second position about a longitudinal axis of the plug, and a lock. The lock has a first locked position preventing rotation of the plug relative to the shell, an unlocked position allowing rotation of the plug relative to the shell and a second locked position different from the first locked position preventing rotation of the plug relative to the shell. The lock is moveable from the first locked position preventing rotation of the plug relative to the shell to the unlocked position with a first movement of the lock, the first movement having a vector component along the longitudinal axis of the plug and a vector component along an axis transverse to the longitudinal axis of the plug.

Key and core with cam blocking

Lock indicators useable to signal the locked or unlocked state of a lock where the lock indicator is usable with an adjustable rose for accommodating various door thicknesses.

Lock status indicator

A motorized latch retraction system for transitioning a latch of an exit device from a latched position to an unlatched position is provided. The motorized latch retraction system includes a lock indicator indicating the latched or unlatched position of the latch and a floating motor.

Assembly for exit device

Lock indicators useable to signal the locked or unlocked state of a lock at both sides of a door selectively secured by the lock. Lock indicators include a first cuff for receiving an input causing the first cuff to transition from a first position to a second position associated with the locked state and the unlocked state. The lock indicators include a second cuff for receiving input from the first cuff via a transmission rod causing the second cuff to transition from a first position to a second position associated with the locked state and the unlocked state.

System and method for transferring rotation of lock indicator through cylindrical lock

Lock indicators useable to signal the locked or unlocked state of one side of a cylindrical lock across the door selectively secured by the lock. For example, the present disclosure provides a cylindrical lock having an entry function with an indicator viewable by occupants of an area secured by the cylindrical lock. The lock indicators are magnetically driven.
