Abstract: A door latch control apparatus for use on a panic exit door allowing the door to be unlatched either manually or electrically is disclosed. Manual latch retraction is accomplished by pushing inwardly a push bar. Electrical latch retraction is accomplished by energizing a solenoid. A unique linkage system is provided to allow for the independent operation of the manual and electrical latch retraction. The apparatus also provides for the door to be dogged, i.e., securing the latch in the unlatched position, either manually or electrically. Manual dogging may be accomplished with the use of a fail safe dogging mechanism. Electrical dogging is accomplished by leaving the solenoid energized and thus the latch retracted.
