Abstract

A status monitoring device for a fenestration unit is provided. The device is positioned in or on the fenestration unit and includes a panel position sensor and a lock status sensor. The device is capable of transmitting panel position data and lock status data to a remote device, trigger an audible alarm on the device or the remote device, trigger a visual alarm on the device or the remote device, or a combination of these.

Claims

1. A status monitoring device for a window or door, the window or door including at least one panel moveable between an open panel position and a closed panel position, the window or door including at least one locking member moveable between a locked position and an unlocked position, the device comprising:

a first sensor that detects a detected panel position, which can be intermediate between and include the open panel position and the closed panel position;

a second sensor that detects a detected lock position to indicate whether the at least one locking member is in the unlocked position or in the locked position;

a code generator that generates codes, the codes including a locking member status code separate from a panel status code, the locking member status code indicating the detected lock position of the locking member and the panel status code indicating the detected panel position of the panel.

2. The device of claim 1 wherein the first sensor of the monitoring device detects a change in panel position from an initial intermediate open position and in response generates at least one of a code, an audible signal, and a visible signal.

3. The device of claim 1 further comprising a transmitter that transmits event packets to a status code receiver, wherein the event packets contain codes indicating the detected panel position and the detected lock position.

4. The device of claim 3 wherein each element of the code indicates both a panel position status and a locking member position status, and wherein the elements of the code comprise:

the at least one panel closed, the at least one locking member locked;

the at least one panel closed, the at least one locking member unlocked;

the at least one panel open, the at least one locking member locked;

the at least one panel open, the at least one locking member unlocked;

the at least one panel intermediate between open and closed, the at least one locking member locked;

the at least one panel intermediate between open and closed, the at least one locking member unlocked.

5. The device of claim 3 wherein the elements of the code comprise:

the at least one panel closed, the at least one locking member locked;

the at least one panel closed, the at least one locking member unlocked;

the at least one panel closed, the at least one locking member locked or unlocked.

6. The device of claim 3 wherein the event packet contains separate codes for the detected panel position and for the detected lock position.

7. The device of claim 3 wherein the event packets are transmitted in response to changes in the detected panel position or detected lock position.

8. The device of claim 3 further comprising an indicator that produces a signal in response to the generation of the event packets.

9. The device of claim 8 wherein the signal is an audible sound or a visible light.

10. The device of claim 9 wherein the audible sound is an emergency sound indicating that the at least one panel has been opened beyond the predetermined position.

11. The device of claim 3 wherein the status code receiver translates and retransmits the status codes to an information collection unit using a protocol compatible with the information collection unit.

12. The device of claim 3 wherein the elements of the code comprise:

the at least one panel open, the at least one panel moving in a direction of the closed panel position;

the at least one panel open, the at least one panel moving away from an original position of the open panel position;

the at least one panel closed from the open panel position, the at least one locking member unlocked.

13. The device of claim 1 wherein the at least one locking members is moved between the locked position and the unlocked position or the unlocked position and the locked position by activating an electronic circuit or electromechanical device.

14. The device of claim 13 further comprising at least one sensor for sensing at least one electrical effect occurring during movement of the at least one locking member.

15. The device of claim 14 wherein the sensed electrical effect indicates engagement of the locking member.

16. The device of claim 1 wherein the code generator generates a detected panel position code in response to movement of the at least one panel from the detected panel position.

17. The device of claim 1 wherein the status monitoring device can be retrofit adjacent to a locking assembly.

18. The device of claim 1 wherein the status monitoring device is capable of arming an alarm with the at least one panel in the open panel position.

19. The device of claim 1 wherein the first sensor detects movement of the at least one panel from the detected panel position independent of whether the at least one locking member is in the locked position.

20. The device of claim 1 wherein the first sensor detects movement of the at least one panel from the detected panel position with the at least one locking member in the unlocked position.

21. The device of claim 1 wherein the status monitoring device triggers an alarm if the at least one panel is moved from the detected panel position.

22. The device of claim 1 wherein the second sensor detects the position of the locking member by coupling with a moving member of the at least one locking member.

23. The device of claim 22 wherein the moving member is a rotating latch.

24. The device of claim 22 wherein the moving member is a slide bar coupling a latch to an operator.

25. The device of claim 22 wherein the moving member is a rotating operator that operates a member that couples to a latch.

26. The device of claim 22 wherein the moving member is a deadbolt lock.

27. The device of claim 22 wherein the moving member comprises a magnetic element, an optical element, a mechanical coupling element, a sonic element, or an RFID element.

28. The device of claim 1 wherein the second sensor detects the position of the at least one locking member by coupling with a moving member of the at least one locking member wherein the coupling is magnetic, optical, mechanical, sonic, or RFID.

29. The device of claim 1 wherein the status monitoring device is not integrated into the at least one locking member or at least one lock actuator.

30. The device of claim 1 wherein the status monitoring device can be retrofit onto a previously installed window or door.

31. The device of claim 1 wherein the status monitoring device is capable of arming an alarm with the at least one locking member in the unlocked position.

32. The device of claim 1 wherein the status monitoring device is capable of arming an alarm when the detected panel position is not the closed panel position.

33. A status monitoring device for a window or door, the window or door including at least one panel moveable between an open panel position and a closed panel position, the window or door including at least one locking member moveable between a locked position and an unlocked position, the device comprising:

a first sensor that detects a detected panel position intermediate between and including the open panel position and the closed panel position;

a second sensor that detects a detected lock position to indicate whether the at least one locking member is in the unlocked position or the locked position;

the status monitoring device being capable of arming an alarm with the at least one locking member in the unlocked position.

34. The device of claim 33 further comprising a sensor that detects movement of the at least one panel from the detected panel position independent of whether the at least one locking member is in the locked position.

35. The device of claim 33 wherein the first sensor detects movement of the at least one panel from the detected panel position with the at least one locking member in the unlocked position.
