Wiring guide: DoorKing 6100

This guide shows where each wire from the Nimbio terminal strip lands on the DoorKing 6100’s control board, and which switch setting the relay needs. Gate Status: wired on the main board. Sense 1 and SC connect across the board’s dry relay contact, and Nimbio maps the relay’s two states to the labels shown in the app.

Note: This operator cannot supply enough continuous power for Nimbio. Use a separate 12–24V AC or DC power supply.

Before you start

Power the operator down at its supply before touching any terminal.
The Nimbio terminal strip has eight terminals: PWR+, PWR-, Sense 2, SC, Sense 1, NC, C and NO. This guide wires PWR+, PWR-, SC, Sense 1, C and NO; Sense 2 and NC are not used (see “Connections”).
Power: PWR+ and PWR- go to a separate power supply, not to the operator board. Terminal 7 (24 VAC) is limited to 250 mA for everything connected to it, so do not power the Nimbio from it. The Nimbio accepts 6.5 to 24 V AC or DC; either supply lead can go to either PWR terminal.
You need a small screwdriver for the terminal screws.

When the wiring is done, restore power at the supply. A Nimbio support team member then calls to test the gate before you close the panel.

Settings on the operator

Set these switches on the SW4 switch bank of the control board:

Gate Status relay (terminals 16 and 17): SW4-1 OFF, SW4-2 ON (“Not Closed” mode).
Full Open (terminal 11): SW4-3 ON (standard input), SW4-4 ON (auto-close), SW4-5 ON (swing gate mode).

Gate Status

Gate Status: wired. Sense 1 (terminal 16) and SC (terminal 17) connect across the dry relay contact. With SW4-1 OFF and SW4-2 ON, the relay is active whenever the gate is not closed, and Nimbio maps its two states to the labels shown in the app. Sense-line polarity does not depend on the wiring. Nimbio maps each sense line’s triggered and untriggered state to an Open or Closed label after installation. If Gate Status shows the opposite of the physical gate, contact Nimbio support to have the labels switched; no rewiring is needed.

No suitable output on your operator? A magnetic gate switch can report the gate’s position instead: wire its two leads to Sense 1 and SC for fully closed, or to Sense 2 and SC for fully open. The switch must be a dry contact that puts out no power of its own; if yours puts out power, add a relay that turns it into a dry contact.

Frequently asked questions

Does the DoorKing 6100 need an expansion board for Gate Status? +

No. Sense 1 and SC land on the dry relay contact of the main control board, terminals 16 and 17.

Which Nimbio terminals open the gate on the DoorKing 6100? +

NO and C, wired to Full Open (terminal 11) and Low Voltage Common (terminal 20). The Nimbio relay closes NO to C, which the 6100 reads as an open command on its access-control input.

Why is Sense 2 not used on the DoorKing 6100? +

Terminals 16 and 17 are the two sides of one relay contact. One contact reports one state, so Sense 1 and SC across it is the complete connection; a second sense line on the same contact would only mirror the first.

Is the Nimbio NC terminal used on the DoorKing 6100? +

No. The operator input takes the NO and C pair, so NC stays empty.
