Abstract

A door assembly includes a first door skin and a second door skin spaced apart from the first door skin. The assembly also includes an energy sensor generating an energy signature signal and a memory storing a door component operating signature. A controller is coupled to the accelerometer and forms a comparison of the energy signature signal to the door component operating signature and generates a door component operation status signal in response to the comparison.

Claims

1. A method for determining if a facility, having multiple doors, is in compliance with codes and/or regulations, wherein each door comprises an energy sensor, a memory and a door controller, the method comprising:

generating a plurality of energy signature signals, with the energy sensor of each door;

comparing each energy signature signal to a door component operating signature stored by the memory of each corresponding door;

generating a plurality of door component operation status signals in response to the comparing;

communicating the door component operation status signals to a manufacturer controller; and

generating a compliance report with the manufacturer controller.

2. A method as recited in claim 1 wherein comparing comprises comparing each energy signature signal to a plurality of door component operating signature patterns.

3. A method as recited in claim 1 wherein the door component operation status signal corresponds to an improperly adjusted door operator assembly, and the improperly adjusted door operator comprises a high swing speed.

4. The method of claim 1, wherein the energy sensor comprises an accelerometer.

5. The method of claim 1, wherein the energy sensor comprises a multi-axis accelerometer.

6. The method of claim 1, wherein the door component operation status signal corresponds to a door position.

7. The method of claim 1, wherein the door component operation status signal corresponds to a latch status.

8. The method of claim 7, wherein the latch status comprises a latch stop not aligned with the door.

9. The method of claim 7, wherein the latch status comprises a latch not securely latching.

10. The method of claim 1, wherein the door component operation status signal corresponds to a hinge status.

11. The method of claim 1, wherein the door component operation status signal corresponds to a door clearance.

12. The method of claim 11, wherein the door component operation status signal corresponds to a door-to-frame clearance.

13. The method of claim 1, wherein the door component operation status signal corresponds to an abuse of the door.

14. A method for determining if a facility, having multiple doors, is in compliance with codes and/or regulations, wherein each door comprises an energy sensor, a memory and a door controller, the method comprising:

generating a plurality of energy signature signals, with the energy sensor of each door;

comparing each energy signature signal to a door component operating signature stored by the memory of each corresponding door;

generating a plurality of door component operation status signals in response to the comparing;

communicating the door component operation status signals to a central controller;

generating a compliance report with the central controller; and

communicating the compliance report to a manufacturer controller.

15. The method of claim 14, wherein the energy sensor comprises an accelerometer.

16. The method of claim 14, wherein the door component operation status signal corresponds to a latch status.

17. The method of claim 16, wherein the latch status comprises a latch stop not aligned with the door.

18. The method of claim 16, wherein the latch status comprises a latch not securely latching.

19. The method of claim 14, wherein the door component operation status signal corresponds to a hinge status.

20. The method of claim 14, wherein the door component operation status signal corresponds to an abuse of the door.
