These units are flush mounted in place of the regular door strike plates. The door remains locked until the door is electronically actuated by a remote contact device. For AC models, use with a 592 Transformer.

For use in apartments, offices, banks, industrial buildings, schools and institutions. Use in door interlocking and control systems with timed or manual operation.
