Abstract
A panic device for rapidly unlocking an entryway includes a touch bar handle configured for activating the panic device; and a push arm assembly mechanically connected to the touch bar handle, and configured for operating a latch mechanism connected to the push arm assembly via a plurality of linkages. Activation of the panic device, including depressing the touch bar handle, activating the push arm assembly, and the operation of the latch mechanism generates a noise reduction in the range of approximately 20-99 percent and at least 30 decibels during operation of the latch mechanism.
