Genuine DoorKing 1871-010 control board — the main board for the DoorKing 1812 Classic telephone entry system, models 1812-081. The Classic is the residential version with no phone line of its own; it dials through the house phone.
Three 1812 boards — read the number on yours. The 1812 was built in Classic, Plus and Access Plus versions, and each takes its own board. The board number is the fastest way to tell them apart:
| 1812 version | Control board | Transformer |
|---|---|---|
| 1812-081 Classic, surface | 1871-010 | 1804-059 24 VAC |
| 1812-089 Plus, surface | 1971-010 | 1804-060 16.5 VAC |
| 1812-095 Plus, curved | 1971-010 | 1804-060 16.5 VAC |
| 1812-090 Access Plus, surface | 1970-010 | 1804-060 16.5 VAC |
| 1812-096 Access Plus, curved | 1970-010 | 1804-060 16.5 VAC |

Is the board actually the problem?
| Symptom | Check first |
|---|---|
| Unit dead, no display | Transformer and power wiring before the board |
| Display alive but the unit will not dial or answer | The phone line at the terminals — confirm dial tone with a handset first |
| Keypad or call button dead, display alive | The 1895-017 keypad and its ribbon, then the board |
| Powers up but ignores everything; relays never fire | The board |
| Talks and dials, but the door relay never fires | The relay wiring and the strike or maglock supply, then the board |
| Failed after a storm | Surge damage on the phone line or power — the board, and fit phone-line surge protection with the replacement |
After fitting
Your programming does not carry over on the 1812. Codes and settings live on the board; re-enter them from your records, or reload them from the DoorKing software if the unit is programmed remotely. Then confirm talk time, relay strike time and tone-open codes before handing the system back.
