Start with the device and the symptom.
A short, reproducible report helps us identify the right next step. Contact the team for device operation, installation references or integration questions.
Identify your equipment
Include FC6820 and its configuration, order reference if available, firmware and application version. A photo of the device label helps distinguish configurations.
Show the setup
Describe the power supply, interface, connected controller or host, and mounting. Include a wiring diagram or clear connection photo where relevant.
Describe what happens
List the steps, expected result, actual result and whether the issue is repeatable. A short video or sanitised log can help. Remove passwords, tokens and personal biometric information.
Find the right reference.
Use the download centre to find documents by model. If your configuration’s manual is not listed, request it with the model and firmware so the team can identify the appropriate version.
Before returning equipment.
Contact the team with the product and order details before sending a device back. Warranty eligibility, inspection, repair, shipping and return authorisation are reviewed against the applicable order and product terms.

Common questions for FC6820.
What should I include in a technical support request?
Include the overseas product model, firmware or software version, connection method and a short sequence that reproduces the issue. Screenshots, indicator behavior and relevant logs help; do not send passwords, access credentials or personal biometric data.
What should we check if a device repeatedly restarts?
Compare the power supply voltage, current capacity and wiring with the specification for the selected configuration. If the problem continues, record whether it happens at startup or during a particular action and send the model, firmware and observations to technical support.
Does every FC6820 include door-control connections?
No. Select the reader or access-control configuration first. Exit-switch and door-contact inputs and relay output apply to the access-control configuration. Match the supplied harness and firmware to the connection reference; a shared model family does not make every version interchangeable.
Can the same configuration tool be used for every reader?
Do not assume so. Reader firmware and access-control firmware can use different tools, configuration codes or platform commands. Share the overseas model, firmware and intended operating mode so the matching method can be checked before changing settings.
Is a network connection the same as a connection to the management platform?
No. A device can have local network access without maintaining its platform or messaging connection. Check the physical network, IP settings and service connection separately, using the indicators or logs available for the selected system.
