How to Fix Honeywell Vista 103 LngRng Radio or bF Error

Today, I will look at the Honeywell Vista panel, which includes the 21 IP, 20P, and 15P and is compatible with most other Vista panels. To begin, let us examine the issue: 103 Radio LngRng or bF Error.

Honeywell Vista 103 LngRng Radio or bF Error

Check 103 Long Range Radio is the most frequently encountered error code. On fixed English keyboards, it is displayed as bF. This indicates that a communication error has occurred in your long-range radio.

A long-range radio is a module that connects to the Internet or a cellular network if you have a 21 iP and an Ethernet connection, a backup cellular connection, or the 7847i Ethernet module, or the GSMV4G, the GSMX4G, or even the iGSMV4G.

If any of these devices lose signal, whether it’s an Internet or cellular connection, and your communication with the alarm center – or more precisely, with the Honeywell Alarm Net server that hosts all communications – if that connection loses signal for any reason, whether your Internet router is shut down or the connection is otherwise signaled, or the cellular signal goes down for any reason, you’ll receive a Check 103 notification.

Fixing the error code is Check 103 Long Range Radio.

Solution 1: Reconnecting or restoring the connection

If your Internet connection is restored after an interruption, you might need to troubleshoot. Once the connection is restored, you can proceed to double defuse using the keyboard.

This will restore the default value of 1234 in our master code set.

  • We have the number 1234, followed by the number one.
  • This completes the single disarm.
  • And then we are back to 1234.
  • This completes a second disarming.

At this point, we still have a problem because the Ethernet connection that we use to connect to our Vista 21iP is currently down.

Consequently, in this scenario we would need to reconnect and disable the device again to fix the problem.

This is the case when you reconnect while being monitored. For example, let us say you have a Vista panel. Maybe you recently bought a new house or disabled monitoring a device, and you still get this message that you do not want to receive.

Solution 2: Do some simple programming (it sounds scarier than it is!)

If you’re still facing problems, the first step should be to address the programming. Now, you’ll require the installer code. Therefore, if the house is new and you do not have the codes, you must access the programming via the back door.

That means you’ll need to delve into the Vista panel’s programming.

And that requires a reboot, which involves disconnecting the AC transformer and battery, reconnecting them, turning on the computer, and simultaneously holding down the star and square buttons for at least three seconds within the first minute.

This enables you to begin programming immediately.

  • We are going to enter 4112 and 800.
  • Our panel’s default installer code will remain 4112.
  • It will display installer code 20.

This is the code you will see after rebooting the system and entering through the back door. Once you are in programming, navigate to the Star 29 field. This is critical now.

The 6160 keypads, also known as alphanumeric keypads, are the only keypads that provide access to the Star 29 menu and advanced diagnostics and programming functions.

Therefore, after deactivation, we need to make sure that we press zero to exit the menu and avoid getting stuck in the advanced communications programming menu.

Therefore, the option is “Enable IP/GSM, No-Yes.” So if you get the error message COM, it is most likely enabled.

And if you are not connected to anything, and you are not being monitored – for example, if you are disconnected from the Internet and do not want to be monitored at the moment – you can click No and enter a zero.

You will notice the zero. This will remove you from this field completely. You have returned to the home screen – the main menu – and are still in programming mode, so do not press any crazy keys until you are done.

We will start with 9 9. A 9 appears on the screen and then disappears.

Back to disarming and rearming.

Each time you enter and exit programming, you must remember to re-enable the chime if it was previously enabled. If not, you can remove it.

The general procedure is to disable the Check 103 Long Range Radio first.

Remember that if you have monitoring, the best course of action in an Internet or cellular outage is to reboot the router, followed by checking other Internet devices.

If you need the help of your alarm company, be sure to contact them. They can provide you with cellular signal measurements to verify what is happening on your cellular network.

Once communication is restored, you can perform the master code, followed by disarming – which is disarming.

Repeat this twice.

This will fix the problem with Check 103 and the bF code that appears on your keypads.

This is how you solve communication problems with your long-range radio if you have further questions about the Check 103 manual on your Honeywell Vista.
