An actuator-controlled strike comprising a housing disposable within a doorframe and including a cavity for a spring latch and a dead latch of a mortise-typelockset. A keeper is pivotably mounted within the chamber to engage the spring latch. A pivotably mounted kicker cooperates with the keeper. A pivotably mounted dead latch release is supported by the keeper when the spring latch is within the strike. The keeper is released by the actuator and rotates into a position to ramp the spring latch out of the strike, also allowing the dead latch release to release the dead latch into the cavity, allowing the spring latch to be ramped out of the strike. Pivoting the keeper causes the kicker to urge the spring latch onto an exit ramp on a face of the keeper. The dead latch release can be installed in a plurality of different locations in the housing.
An actuator controlled strike for operating in conjunction with a spring latch and a dead latch of a lockset, said strike comprising:
