Abstract
The panic exit device includes several features which improve its ease of use and operability over earlier devices including: (1) an improved latch deadlocking mechanism; (2) an improved latch to pad mechanism; (3) a pad lock down feature; (4) an improved universal mounting plate and easily mounted strike; and (5) a vertical rod-bottom bolt deadlocking mechanism in its center case. The latch deadlocking mechanism includes a deadlock link, which in the event of a fire, will block the movement of the latch bolt.
