Troubleshooting a beeping Touch IO Reader

Under certain conditions, PDK Touch IO readers can enter a continually beeping state, this article will detail several troubleshooting steps that can be taken before contacting ProdataKey technical support 

1. Determine if a low battery is causing the Reader to have power issues

If the Controller that the Touch IO reader is attached to is charging an extremely low battery, the Touch IO reader will enter a beeping state due to insufficient power being supplied to the reader. This is due to the reader drawing significantly more amperage than other readers (a Touch IO reader draws 300ma+ compared to other readers drawing approximately 30ma) and results in the reader being in a brownout condition.

Steps to troubleshoot if this is the cause:

1. Disconnect the battery and main power from the Controller
2. Reconnect main power to the Controller
3. Confirm if the Reader continues beeping or not.
   

If a low battery is the cause of the beeping, we recommend charging the battery using another controller that is not connected to a Touch IO reader.

2. Determine if the Reader is overheating

If the Touch IO Reader is mounted in any of the following ways and enters a beeping state only during certain times of day, the Reader may be overheating and will continually beep until the Reader cools down.

• Mounted with prolonged, direct sunlight
• Mounted directly on a metal-sided building
• Mounted directly on a metal mullion 

If the Reader is mounted in these ways, the Reader will either need to be insulated from the heated mounting surface or shaded to reduce the temperature of the reader. This can be done by installing a gasket between the Reader and the metal surface or through a mounting solution that shades the Reader.

If the above troubleshooting steps have been addressed, please reach out to ProdataKey Technical Support for possible additional troubleshooting steps.
