Use the AC41 Test Buttons

Learn how to use the AC41 test buttons for setup and troubleshooting

Updated over a week ago

The Verkada AC41 4-Door Controller has 4 buttons to help test or emulate different events. Test buttons help you test the relays of the controllers and the request-to-exit (REX) and door position indicator (DPI) inputs on the individual ports.

Required. The controller needs internet access for the test buttons to operate.

Door button

  1. Press the DOOR button to cycle which door is selected for testing. The selected door has its corresponding LED turned on. For example, if door 2 is selected, the LED under 2 would be on.

  2. Once you select a door, the 3 LEDs indicate the status of the circuit, as shown below.

Trigger Lock button

When the LED is on, it indicates that the lock is locked. When the LED is off, the lock is unlocked.

Emulate DPI button

When the door is closed, the LED is on, indicating that the circuit is complete. If the door is open, the circuit is open (the LED is off).


When the EMULATE REX button is triggered, the circuit is complete (the LED is on). In the resting state, if no one is detected by the REX, then the LED is off.

When you press and hold the EMULATE REX button, the controller switches the current state of the DPI or REX.


If the DPI LED is on, it means the door is closed. If the EMULATE REX button is pressed, the LED turns off (the door is open).
