Security System Error Codes: Sensors, Panels, Battery, and Communication Issues

Use this guide to identify whether the issue is sensor state, panel communication, battery health, or authentication/certificate policy—then apply safe fixes.

TL;DR

✓ Start by identifying the layer: sensor, panel, communication path, or account/auth policy.
✓ Battery and communication issues are common and can mimic “system failure”.
✓ For authentication/certificate errors, verify time/date and trust chain before deeper changes.
✓ Avoid disabling security controls; use vendor guidance and logs.

Symptoms / When you see this

✓ Panel shows trouble codes or communication loss.
✓ Sensors report tamper/low battery/offline.
✓ Account login fails or certificate errors appear in logs.
✓ System intermittently arms/disarms or loses connectivity.

Root causes (grouped)

✓ Sensor battery/placement issues.
✓ Panel-to-sensor RF range/interference.
✓ Internet/cellular path problems (DNS, firewall, carrier issues).
✓ Account policy restrictions and auth failures.
✓ Certificate trust and time sync problems.

Step-by-step fixes (safe, prioritized)

✓ Confirm power and connectivity at the panel (internet/cellular).
✓ Check low battery alerts and replace batteries with correct type.
✓ Reduce interference and confirm sensor placement/range.
✓ Verify system time/date for certificate/auth flows.
✓ Use vendor diagnostics for communication and account policy issues.

What NOT to do

✓ Do not disable safety/security features permanently.
✓ Do not ignore repeated tamper alerts; verify sensor mounting.
✓ Do not share security credentials insecurely.

If it persists (escalation checklist)

✓ Capture panel logs, timestamps, and device identifiers.
✓ Confirm whether failures follow network changes.
✓ Use vendor support for auth/policy issues and persistent comm faults.

✓ Security-related codes often have environment-specific causes. Use code pages as a safe starting point, then confirm with your system vendor.

Code	Meaning	Next step
0x80092013	Certificate revocation check failed — Windows could not complete certificate revocation checking, often because the revocation server could not be reached.	Follow the checklist on the code page
0x800B0109	Certificate chain not trusted — Windows could not validate a certificate chain to a trusted root authority.	Follow the checklist on the code page
0xC0000064	No such user — The specified user name does not exist or could not be found by the authentication system.	Follow the checklist on the code page
0xC000006F	Invalid logon hours — The user is not permitted to log on at this time based on account restrictions.	Follow the checklist on the code page
0xC0000070	Invalid workstation — The account is not allowed to log on from the workstation or host it attempted to access.	Follow the checklist on the code page
0xC0000071	Password expired — The account password has expired and must be changed before login can succeed.	Follow the checklist on the code page
0xC0000133	Time difference at domain controller — Authentication failed because the client and domain controller times differ beyond allowed limits.	Follow the checklist on the code page
0xC000015B	Logon type not granted — The account is not allowed to log on using the requested logon type (e.g., RDP, service, network).	Follow the checklist on the code page
0xC0000192	Account restriction — Authentication failed due to an account restriction rather than incorrect credentials.	Follow the checklist on the code page
0xC0000224	Password must change — The account requires the password to be changed before it can be used to log on.	Follow the checklist on the code page
0x80090302	Unknown credentials — The security layer did not recognize the credential type or required material.	Follow the checklist on the code page
0x80072F8F	Security error — A certificate or secure connection validation step failed.	Follow the checklist on the code page
0x80090305	Security internal error — A security provider encountered an internal failure while processing the request.	Follow the checklist on the code page
0x80090308	Invalid token — A security token or credential material was not accepted as valid.	Follow the checklist on the code page
0x8009030E	No credentials — A security layer could not find credentials to complete authentication.	Follow the checklist on the code page
0xC000006A	Wrong password — Authentication failed because the provided password was not accepted.	Follow the checklist on the code page
0xC000006D	Logon failure — Authentication failed because credentials or required validation did not succeed.	Follow the checklist on the code page
0xC0000072	Account disabled — Authentication failed because the account is disabled.	Follow the checklist on the code page
0xC0000193	Account expired — Authentication failed because the account is expired.	Follow the checklist on the code page
0xC0000234	Account locked out — Authentication was blocked because the account is locked.	Follow the checklist on the code page

FAQ

Is every security logon error an attack?

No. Misconfiguration and automation can generate failures. Correlate with source hosts and timing.

Why does time sync matter?

Time skew can break authentication and certificate validation.

What is the safest first fix?

Confirm connectivity/power, replace low batteries, and verify time/date.

Should I disable certificate checks?

No. Fix trust configuration instead.

Do sensor batteries cause communication errors?

Yes. Low voltage can cause intermittent sensor drops.

When to call vendor?

For persistent communication loss, account policy blocks, or system-wide failures.

What should I capture?

Exact code, timestamp, panel logs, and network environment details.

Can firewall rules break security systems?

Yes. Cloud-connected systems require outbound access to specific endpoints.
