Doorking Inc PC Board Only, Main Control Board for 1835-080 (No Memory Chip)

It's the main PC board for the Doorking 1835 telephone entry and access control system. Board only, with no memory chip included. The memory chip holds the directory and programming, so if you're swapping a failed board you pull the chip off the old board and move it over. If your old chip is damaged, plan on sourcing one separately, because it isn't part of this package.

No. This is the main control board for the Doorking 1835-080 specifically, and Doorking's telephone entry boards are model-specific. Order the board that matches the model number printed inside your panel door, not just the family.

The main control board runs the dialing, the directory logic, and the relay outputs on the 1835, so a panel that powers up but won't place calls or respond to entry codes is a common board-level failure. Before you order, confirm the panel is getting proper power from its transformer and that the phone line itself is live, since either will mimic a dead board. When you do swap it, the memory chip carries your resident directory and codes, and this replacement ships without one, so keep the chip from the original board.

Not if the memory chip from your original board is intact. The directory and programming live on that chip, and this replacement is supplied as the bare board so the chip transfers with you. That's the difference between a fifteen minute swap and re-entering several hundred residents by hand.

Board only. You get the PC board itself, not the enclosure, keypad, faceplate, or transformer. If your panel housing is damaged or you're doing a new installation rather than a repair, you need a complete 1835 unit instead of this part.

Yes, the 1835 main control board is classified for commercial applications, which is what you'd expect for a telephone entry system serving an apartment community, gated development, or commercial parking entrance.
