## What you need to know

Ask which AL54 indicator flashed and during which action before treating the report as a credential denial.

## Potentially affected

Applies specifically to the AL54 LED pattern guide. Interpret colors with the observed action and location on the lock; these meanings are not a general color standard for other readers.

## DSE recommendation

DSE recommends training the service desk to ask which LED flashed, where it was, and what the user was doing.

## Article

Ask which AL54 indicator flashed and during which action before treating the report as a credential denial.

## Source facts

The Verkada AL54 wireless lock uses distinct exterior LED indications for granted access, denied access, and a lost connection during a credential scan. The guide describes green for an accepted credential, brief red for denial, and brief white when a scan occurs while the hub connection is lost. Interior LEDs provide separate connection and persistent lock-state indications. Privacy Mode also differs from ordinary access control: the guide describes access being restricted to designated override groups while that state is active.

## Applicability

Applies specifically to the AL54 LED pattern guide. Interpret colors with the observed action and location on the lock; these meanings are not a general color standard for other readers.

## DSE recommendation

DSE recommends training the service desk to ask which LED flashed, where it was, and what the user was doing. Route a lost-hub indication toward connectivity checks instead of immediately replacing a credential or expanding access permissions. Keep the model-specific pattern guide with the maintenance record and identify who may use privacy overrides. Avoid changing a room’s privacy configuration merely to make a reported red indication disappear before its cause is understood.

## Verification

During an approved service test, compare a known permitted credential and a deliberately excluded test credential, observing the exterior indicator and event record. If investigating connectivity, correlate the time with hub status without creating an unscheduled outage. Record the actual pattern and outcome rather than a user’s color description alone.
