System and apparatus for sensing and providing alerts for deadbolt lock status

A deadbolt lock status sensing assembly for monitoring status of a deadbolt member of a deadbolt assembly on a door, the status sensing assembly comprising:

• a sensible element mountable on one of the door and the deadbolt assembly, the sensible element being magnetically active;
• a sensing element mountable on one of the door and the deadbolt assembly;
• wherein the sensible element and the sensing element are configured to move with respect to each other when the deadbolt member of the deadbolt assembly moves between an extended condition and a retracted condition of the deadbolt;
• wherein the sensible element includes an active component and a reactive component, the active component being configured to be actively moved by movement of a deadbolt actuation mechanism and the reactive component being reactively moved by movement of the active component;
• wherein the active component mounted on a deadbolt cam bar of the deadbolt assembly such that the active component is directly rotated with the cam bar when the cam bar is rotated such that the active component is rotated between a locked location and an unlocked location by rotation of the deadbolt cam bar;
• wherein the reactive component has an influenced position and an uninfluenced position, the reactive component being biased toward the uninfluenced position;
• wherein a relatively closer proximity of the active component to the reactive component causes the reactive component to move to the influenced position and a relatively further proximity of the active component to the reactive component permits the reactive component to move to the uninfluenced position;
• wherein the reactive component is mounted on a deadbolt frame of the deadbolt assembly in a chamber formed in the deadbolt frame;
• wherein the chamber is elongated along a movement axis radiating from the deadbolt cam bar, the reactive component being movable in the chamber along the movement axis, the reactive component translating along the movement axis in the chamber between the influenced position and the uninfluenced position;
• wherein the sensing element is configured to detect a change in the position of the reactive component between the uninfluenced and influenced positions;
• and
• wherein the chamber is configured such that the reactive component closes an electrical circuit in one of the influenced and uninfluenced positions of the reactive component and the reactive component opens the electrical circuit in an other one of the influenced and uninfluenced positions of the reactive component.
