Docket No. 0071-SL-VD A PANIC EXIT DEVICE HAVING NOISE SUPPRESSION Abstract of the Disclosure The Device is of the push pad type having a translating action rod which is biased in the latch-extended posi- tion. An abutment is fixed to the action rod to receive thereagainst the extending plunger of a shock absorber which is removably coupled to an open guide base. The base is mounted on a base plate to support action rod operating bellcranks, and to support the action rod therein also. A shock absorber holder is clasped to the guide base, and the cylinder of the shock absorber, in which a viscous fluid is confined, is engaged by the holder to direct the plunger toward the abutment. In the depicted embodiment, the plunger resists retraction, to decelerate and damp the return of the push pad and action rod to their at-rest positions and, consequently, to sup- press the operating noise of the panic exit device.
