Abstract
An exemplary exit device system includes a pushbar assembly and a control system. The pushbar assembly includes a latch having an extended position and a retracted position, a blocking member having a blocking position in which the blocking member retains the latch in the extended position and an unblocking position in which the blocking member permits the latch to move to the retracted position, a pushbar operable to move the blocking member between the blocking position and the unblocking position, and an electronic driver operable to move the blocking member between the blocking position and the unblocking position. The control system is configured to operate the electronic driver to electrically move the blocking member between the blocking position and the unblocking position based upon information received from a credential reader.
