An exemplary noise-reducing mechanism for door hardware includes a housing, a damper, and a stop. The door hardware includes a first component and a second component, and an operational movement of the door hardware causes relative movement of the first and second components. The housing is mounted to the first component, and the damper is mounted to the housing. The stop is mounted to the second component such that the stop engages the damper during the operational movement. The damper is configured to slow the operational movement, thereby reducing noise generated by operation of the door hardware.

Door hardware noise reduction and evaluation

An exemplary exit device includes a pushbar assembly, a remote latching assembly, and a coordination mechanism. The pushbar assembly includes a latch control assembly, and the coordination mechanism biases the latch control assembly toward its actuated state. The remote latching assembly includes first and second latch mechanisms, and the latch control assembly is operable to actuate the latch mechanisms. Each of the latch mechanisms at least selectively urges the latch control assembly toward its deactuated state such that the remote latching assembly exerts a variable deactuating force on the latch control assembly. The coordination mechanism selectively retains the latch control assembly in its actuated state, thereby selectively retaining at least one of the latch mechanisms in a corresponding actuated state. When the deactuating force exceeds a threshold force value, the latch control assembly and the latch mechanisms return to the deactuated states thereof.
