10 Easy Steps on How to Clear Base Cover Tamper ADT

Step 1. Disarm Your System:

The first step in addressing the base cover tamper alert is to disarm your ADT security system. To do this, input your access code on the system’s keypad and follow the prompts to disarm. This ensures that the system will not trigger additional alerts or alarms while you are working on it.

If the system is not disarmed, attempting to access the control panel or other components may set off the alarm, creating more hassle.

Step 2. Locate the Component with the Tamper Alert:

Identify the specific component triggering the base cover tamper alert. This could be any part of the security system, such as the main control panel, a motion detector, or a window/door sensor.

Such as the Main Control Panel

Most ADT systems will display the affected component on the control panel screen, helping you quickly locate it without guesswork. The system manual may also have diagrams or descriptions of each component’s location.

Step 3. Inspect the Base Cover:

Once you have identified the component with the tamper alert, carefully inspect its base cover. Look for any signs of damage, misalignment, or looseness that could be causing the tamper alert.

Ensure that the cover is seated properly and that all screws or fastening mechanisms are secure. If the cover appears to be damaged or warped, you may need to replace it with a new one to resolve the issue.

Sometimes, simply re-securing a loose cover can clear the tamper alert. Gently press all the cover’s edges to ensure it is in place, then check the control panel to see if the alert has cleared.

Step 4. Reseal or Replace the Base Cover:

If the base cover inspection reveals that it is not securely fastened, take the time to reseal it properly.

Align the cover with the component and carefully tighten any screws or latches that hold the cover in place. If the cover is damaged beyond repair, you must replace it with a new one, which can usually be ordered directly from ADT or an authorized supplier.

Once the cover is properly secured or replaced, this should resolve the tamper alert. Double-check that the cover is flush against the component and securely fastened to avoid future issues.

Step 5. Reset the Component:

After addressing the base cover, reset the component to ensure the tamper alert is cleared. This can typically be done by pressing a button on the component itself or through the control panel on your ADT system.

Consult your system manual for specific instructions on resetting the component in question. This step is crucial as it allows the system to register that the base cover tamper issue has been resolved.

Step 6. Check for Additional Issues:

Inspect the Wiring

Once you have reset the component, it is important to check for any additional issues that might be causing the tamper alert. Inspect the wiring and connections associated with the component to ensure everything is properly connected and there are no loose or damaged wires.

If you identify any additional problems, address them accordingly before proceeding. Ensuring all connections are secure will help maintain the overall integrity of your security system.

Step 7. Re-arm Your Security System:

After confirming that the base cover is securely in place and there are no further issues, it is time to re-arm your ADT security system. Input your access code into the keypad and follow the prompts to re-arm the system.

This step will activate the security system and ensure that it is ready to protect your home. Monitor the system for a few minutes to verify that the tamper alert does not reappear.

Step 8. Monitor the System:

Continue to monitor your ADT security system closely for the next few hours to ensure the tamper alert does not recur. Keep an eye on the control panel display and listen for any warning chimes that might indicate a problem.

Confirming that the issue has been fully resolved and that your system is functioning correctly is important. Additionally, check the system periodically in the coming days to ensure the tamper alert does not return.

Step 9. Contact ADT for Assistance:

If you have followed the previous steps and the base cover tamper alert persists, it’s time to contact ADT for professional assistance. ADT’s customer support team is equipped to handle various issues and can offer expert guidance to resolve the tamper alert.

When you call, have your system’s model number, installation date, and any specific error codes from your control panel at hand. This information will help the support team diagnose the problem more quickly and accurately.

Step 10. Schedule a Technician Visit:

Sometimes, the tamper alert may be due to a more complex issue requiring a professional technician’s intervention.

ADT can schedule a service visit to your home, where a technician will thoroughly inspect your security system, troubleshoot any persistent issues, and make necessary repairs or adjustments to ensure your system operates correctly.

Inspect Your Security System

Regular maintenance by a professional can also prevent future problems and extend the life of your security system.
