What Does "103 check lngrng radio" Mean On My ADT System?
The message "103 check lngrng radio" on your ADT System means that there is a problem with the system's backup communicator. The message will appear on an Alphanumeric Keypad for an ADT Safewatch Pro 2000 System or an ADT Safewatch Pro 3000 System that is experiencing communication issues.
An ADT Safewatch Pro System is actually just a re-branded Honeywell VISTA System. With that in mind, an ADT Safewatch Pro will display the same errors messages as what you will see on a Honeywell VISTA Panel. The Check 103 Error message indicates that there is something wrong with the system's communicator. The message can only appear on Alphanumeric Keypads. If you have a Fixed English Keypad for your ADT System, then you will see bF instead, which means "backup failure". Either way, Check 103 and bF indicate the same issue. The only way to clear the issue is by setting up a properly functioning and registered communicator with the panel and then performing a double disarm. A double disarm can be performed by entering [Master Code] + [1] + [Master Code] + [1].
If you have an ADT System using the original communicator that came with it, then you should be aware that the communicator is proprietary to ADT. In other words, you will not be able to use that communicator with a monitoring company other than ADT. However, there is a good chance that you may be able to use your existing system with a different monitoring company by simply installing a different communicator. In that scenario, you may also want to replace the PROM Chip to make programming easier. We strongly recommend that you contact your new monitoring company for further instructions. If you are starting service with Alarm Grid, then you should email us at support@alarmgrid.com before taking any action. We will need to know your system model, its communicator, and its PROM Chip revision number.
If you are an active ADT customer and you see a Check 103 or bF message, then you should contact ADT for further assistance. They are the only ones who can properly troubleshoot an ADT Communicator. Keep in mind that there are many issues that can cause a Check 103 or bF message to appear. These include, but are not limited to, a loose tamper cover, the communicator not being registered, and the communicator losing contact with its monitoring network. Alarm Grid can only properly diagnose a Check 103 message if the system is set up with our monitoring services.
