Abstract
A mortise lock assembly is disclosed that enables a position of a door associated with the mortise lock assembly to be determined despite whether a deadbolt is in a retracted state or an engaged state. An auxiliary latch assembly transitions between an engaged state and a retracted state. A main latch assembly may also transition between an engaged state and a retracted state. A magnetic field sensing device that is positioned on the auxiliary latch assembly detects a magnetic field generated by a magnetic field generating device positioned on a door strike. The magnetic field sensing device is positioned on the auxiliary latch assembly such that the magnetic field sensing device is aligned with the magnetic field generating device positioned on the door strike when the door is in a closed position. The magnetic field sensing device may also be positioned on the main latch assembly in a similar manner.
