Claim 17:
18. An electric strike, comprising:
a housing;
a keeper pivotally mounted in the housing, wherein the keeper is biased toward a closed position and is selectively pivotable to an open position;
a lock assembly having a locking state in which the lock assembly retains the keeper in the closed position and an unlocking state in which the keeper is pivotable toward the open position;
an electric driver operable to transition the lock assembly between the locking state and the unlocking state; and
an anti-tamper mechanism configured to retain the lock assembly in the unlocking state when the keeper is in the open position, and to permit the lock assembly to transition from the unlocking state to the locking state when the keeper is in the closed position;
wherein the lock assembly is connected with the electric driver via a lost motion connection and a spring;
wherein, with the keeper in the open position, the lost motion connection permits the electric driver to perform a relocking movement while the lock assembly remains in the unlocking state; and
wherein, with the keeper in the closed position, the spring is operable to drive the locking assembly from the unlocking state to the locking state.
