WINDSTORM DAMPER DEVICE
An damping device for an exit device that is configured to resist high velocity movement a latch assembly relative to a baseplate assembly. Pivotal displacement of a bell crank during typical operation of the exit device may cause a protrusion of the bell crank to exert a pulling force on control linkage element that is coupled to a connection link of a latch assembly and a spring damper element of the damper device, thereby operating the latch assembly while also generally by-passing the damping effect of the damping device. When high velocity movement is imparted on an entryway device associated with the exit device, the damper device resists high velocity movement of the latch assembly relative to the baseplate assembly, thereby at least attempting to prevent the latch assembly from moving independently of the baseplate assembly so as to prevent unlatching of a latch of the latch assembly.
