1. A door or window including:
a lock or latch mechanism actuatable between a locked and an unlocked condition;
a system configured to determine the condition of the lock or latch mechanism, the system including:
a module including first and second sensor units;
a magnet configured to be attached to a part of the lock or latch mechanism such that the magnet moves along a magnet path with actuation of the lock or latch mechanism, the magnet having a magnetic axis which is directionally aligned with the magnet path, the magnet path passing both of the first and second sensor units, such that the module is configured to determine a current condition of the lock or latch mechanism by using the first and second sensor units to sense changes in a polarity of a sensed magnetic field generated by the magnet as the magnet moves along the magnet path.
