Abstract: An electrically controlled strike has a strike frame defining a jamb face opening and a strike face opening. A keeper assembly selectively closes across the frame face opening. A lock assembly readily reconfigurable between fail secure and fail safe arrangements locks the keeper in the closed position. The actuator of the lock assembly drives a plunger between first and second positions to lock and unlock the keeper assembly. The plunger is biased to the first position. A lock member is mountable to the plunger in the fail safe configuration wherein the keeper is released when the plunger is in the second position. The locking member is also engageable to the plunger in a fail secure arrangement wherein the keeper is locked when the plunger is in the first position and the keeper is released when the plunger is in the second position. The strike also incorporates a jamming resistant feature for both the fail safe and fail secure configurations.
