Card Reader LED Behavior
Learn about the LED light behavior on Verkada card readers
Verkada card readers indicate their current status by changing the color and pattern of their LED lights. Click through each reader to learn more about their statuses and behavior.
AD31
The AD31 is being phased out in favor of the AD32. If you’re using an AD31, please see below for the LED states.
No LED
The AD31 is not receiving power from the Access Controller’s + and – terminals.
Ensure that the access controller is powered on and that the reader is properly wired.
Flashing white
The AD31 has been connected to the access controller, but the door has not yet been configured in Verkada Command. Here's how to configure the door.
Spinning white
The AD31 is updating, restarting, or cannot connect to the access controller.
Try directly connecting the reader to the access controller. If the issue persists, try moving the reader to another door cassette.
Solid white
The AD31 is active and ready for secure badge entrance.
If the reader remains in this state even when a badge is presented, the badge may be incompatible.
Green
The AD31 has successfully processed a user scan, and access is granted.
Red
The AD31 has identified a negative read, and access is denied.
Ensure the credential has been added to an access user's profile and that an access level grants the user permission to unlock the door. If the AD31 is solid red, this indicates that the door has been told to emergency lock as part of a scenario.
Wiegand Readers
Third-party readers that support the Wiegand protocol will follow their manufacturers' lighting specifications.
All Verkada Weigand connections include a Reject (RLED) and a Grant (GLED) for accessory lights and devices. This is most often used to trigger the Red or Green LED on a Wiegand reader.
If your reader is Red by default, you can connect the RLED to a different light color or follow the directions to change the reader’s default color as specified by the device’s manufacturer.
