Abstract
A door exit device, security system, and method for implementing a delayed egress operating mode and an authorized access operating mode to control access through a door. In one embodiment, the exit device includes an egress enable mechanism including a latch retraction assembly operatively coupled between a push pad and a door latch. The latch retraction assembly retracts the door latch responsive to manual actuation of the push pad. The exit device further includes a delayed egress device having a latch retraction lock that is operatively coupled to the latch retraction assembly to prevent the latch retraction assembly from retracting the door latch coincident with an attempted manual actuation of the push pad. The exit device further includes an access enable device operatively coupled to actuate the latch retraction assembly in response to an authorized access signal. The delayed egress device further includes a lock override that, responsive to receiving the authorized access signal, releases the latch retraction lock to enable non-delayed retraction of the door latch.
