DOOR HARDWARE NOISE REDUCTION AND EVALUATION
An exit device, comprising: a mounting assembly mounted to a face of the door, the mounting assembly including a channel member extending along a horizontal axis; a drive assembly mounted to the mounting assembly, the drive assembly including a pushbar operable to actuate the drive assembly; a latch control assembly movably mounted to the mounting assembly, wherein the latch control assembly is operably connected with the drive assembly such that actuation of the drive assembly causes a corresponding actuation of the latch control assembly, wherein the latch control assembly comprises a rigid rod extending along a vertical axis, and wherein the rigid rod is configured to move in an actuating direction during actuation of the latch control assembly and to move in a deactuating direction opposite the actuating direction during deactuation of the latch control assembly; a remote latch mechanism vertically offset from the drive assembly, wherein the remote latch mechanism is biased toward a deactuated position, wherein the remote latch mechanism is operably connected to the rigid rod such that actuation of the latch control assembly causes a corresponding actuation of the remote latch mechanism, and such that deactuation of the remote latch mechanism causes a corresponding deactuation of the latch control assembly; and a fluid damper engaged between the mounting assembly and the rigid rod, wherein the fluid damper is configured to slow movement of the rigid rod in the deactuating direction, thereby slowing deactuation of the latch control assembly and the remote latch mechanism.
