ABSTRACT:
This electric strike mechanism has a housing, a keeper pivotally mounted in the housing, at least one locking element pivotally mounted within the housing, for pivoting between a first position where the keeper is prevented from pivoting, and a second position where the keeper is permitted to pivot so that the door can be opened, a solenoid connected to each locking element via an actuation mechanism to move each locking element when the solenoid is energized, and a spring biasing the solenoid towards a non-actuated position. The actuation mechanism may be installed in one of two orientations, namely a first (fail-secure) orientation wherein the locking element is in its first position when the solenoid is not energized and wherein energizing the solenoid moves the locking element to the second position, and a second (fail-safe) orientation wherein the locking element is in the second position when the solenoid is not energized and wherein energizing the solenoid moves said locking element to the first position.
