1. A latching device comprising:
a chassis;
a latch bolt configured to move between a latch extended position and a latch retracted position;
a deadbolt configured to move between a deadbolt extended position and a deadbolt retracted position;
a handle lock configured to selectively lock a handle in a locked position and unlock the handle in an unlocked position;
an electromechanical actuator configured to move the handle lock between the locked position and the unlocked position; and
a lock cylinder configured to receive a key, wherein the lock cylinder is further configured to rotate, wherein in a first rotation of the lock cylinder in a first direction the deadbolt is moved from the deadbolt extended position to the deadbolt retracted position and in a second rotation of the lock cylinder in the first direction the latch bolt is moved from the latch extended position to the latch retracted position and the handle lock is moved from the locked position to the unlocked position, wherein moving the latch bolt from the latch extended position to the latch retracted position by rotation of the lock cylinder moves the handle lock from the locked position to the unlocked position, and wherein the lock cylinder is configured to override the locked position caused by the electromechanical actuator upon a power loss to the electromechanical actuator.
