How to Fix Panel Communication Failure on the ProA7PLUS Panel

There are a number of reasons why the Honeywell ProA7PLUS or ProA7 panels may experience broadband communication failure. If your system experiences a communication error, please see below for how to correct this issue.

The most common errors related to persistent communication failure can be resolved by a quick power cycle to your device.

To do this, you will want to disconnect the device from both the power outlet and remove the battery for at least 2 minutes. Once you unplug the device from the outlet, prepare to access the battery by following the below instructions:

1. Remove the screw on the bottom of the control panel, and release the top cleats (or tabs) to remove the control panel from the wall or desk mount.


2. Rotate the Control Panel and lift it from the wall or desk mount, being careful not to damage the wiring and remove the side cover to access the battery.


3. Remove the battery pack.

Note: The backup battery is a rechargeable Lithium-ion Battery Pack p/n 300-10186, rated at 3.6/4.2Vdc, 7500 mAH.

Remember to allow 2 minutes for the system to fully discharge and reset before reconnecting the battery or the power supply.

To restore the panel, replace the battery and secure it into place with the side cover conforming into place. Align the cover over the panel and connect the tabs into place. Replace the screw removed during step 1, and plug back in the transformer to restore power.

Additional Considerations if Power Cycle Did Not Resolve the Issue:

Have you recently experienced a power outage?

The battery which powers your panel during a power outage may need time to recharge fully before there is enough power for the cellular module to communicate. Please allow up to 24 hours for the trouble to pass.

Are there other issues with the power source?

Ensure your panel is powered by an outlet that is not connected to a switch (GFI Switch Outlet) and that it is securely connected to the outlet, and that the outlet is supplying power. You may test the power supply by plugging another device into the outlet.

Is there a potential for signal interference?

Large metal objects and appliances that generate radio frequency can interfere with signaling. Wall materials may also pose an issue. It is best if your system is located near an exterior wall, above ground (not in a basement), and not in the middle of a large structure (like an interior closet far from exterior walls.)

Could the issue be a temporary cellular outage in your area?

If there’s an interruption of cell service in your area, your system’s communication could be impacted.

Errors could be caused by a phone service outage in your area. Interruptions are common when you first switch service providers. New providers may not have activated the necessary wires leading to the panel.
Note: VoIP and Digital Voice Over Cable are not compatible with your security system.
