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 verifying the installation of a plurality of doors at a facility, wherein each door of the plurality of doors in the facility comprises an energy sensor, a memory and a door controller, the method comprising:

generating a plurality of energy signature signals with an energy sensor for 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, and

communicating the door component operation status signals to a central controller or manufacturer controller, wherein

the central controller or manufacturer controller generates an installation verification indicator.

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 signals correspond 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 signals correspond to a door position.

7. The method of claim 1, wherein the door component operation status signals correspond 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 signals correspond to a hinge status.

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

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

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

14. The method of claim 1, wherein the door component operation status signals correspond to a hinge status and a latch status.

15. A method of verifying the installation of a plurality of doors in a facility, comprising:

installing a plurality of doors having an energy sensor, a memory and a door controller,

generating a plurality of energy signature signals with an energy sensor for each door,

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

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

communicating the door component operation status signals to a central controller or manufacturer controller, wherein

the central controller or manufacturer controller generates an installation verification indicator.

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

17. The method of claim 15, wherein the door component operation status signals correspond to a latch status.

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

19. The method of claim 17, wherein the latch status comprises a latch not securely latching.

20. The method of claim 15, wherein the door component operation status signals correspond to a hinge status.
