How do I know where to return the key?

After entering your PIN code and opening the door, you will see an amber light which indicates the return position.

What if I return the key into the wrong position?

If a key is returned to the wrong position, it will be highlighted by a red LED and the correct position will highlighted in green. The touchscreen will display the same information.

The alarm will activate in the following situations:

  • Someone leaves the door open
  • If an impact or shock is detected

Do I need a network connection or PC to use Traka21 or check key activity reports?

No. Traka21 is a stand-alone Plug & Play solution with advanced RFID technology so requirement for network connection or PC is not necessary. You can view all reports directly on the touch screen.

Do I need an application or computer programme to check key activity reports?

No. You can check all reports using the touch screen. However if you wish to format the reports or customise them then the data can be exported in Excel format for manipulation on your computer.

Common Fault Resolutions

Unit will not power up

Possible Cause: Faulty power cable, flat back up battery

Workaround: Ensure that the power supply is correctly connected to the unit and that the adaptor plug is also correctly connected. If operating on the optional back up battery, the battery may have lost its charge. Ensure that a charged battery is inserted into the unit and the power cables are connected correctly.

Door will not open

Possible Cause: Failure of door release mechanism or spring

Workaround: Ensure that the unit is powered up correctly, as the door will not open via pin access when the unit is powered down. Using the master key, attempt to open the unit via the door mechanism override on the base of the unit. If door continues to fail to open, and there are no clear blockages, then there may be a failure with the spring or solenoid, thus requiring the unit to be returned.

Possible Cause: Door striker out of position

Workaround: Using a hex key, loosen the bolts within the plastic housing and adjusting the position of the striker to the correct position to avoid catching the main body of the cabinet. *Use a visual test before fully closing the door, as adjsting the striker too much may result in the unit continuing to fail to open.

Traka21 Door Striker

Screen blank

Possible Cause: Broken screen, unit failed to power up

Workaround: Attempt to enter your pin where the pin number keys on the screen would be. If the unit is producing the key sounds, then the screen may be damaged, requiring the unit to be returned. If there is no sound, ensure that the power supply (mains or back-up) is correctly connected to the unit and that the adaptor plug is also correctly connected.

Unit frozen

Possible Cause: Software glitch

Workaround: Power down the unit and attempt to power back up. Glitches may reset upon system power up. Ensure that the unit is running on the most recent version of the software, which can be downloaded here. If glitch persists, then the unit must be returned.

iFob Failure

Possible Cause: Faulty RFID tag within the fob or failure of the circuit board

Workaround: Place the iFob in question into another blank slot in the unit. If the fob isn’t recognised, then it may be a fault with the RFID chip within the fob, however, if it is recognised, then it could be fault on the circuit board. Attempt to place a working iFob within the slot in question to determine the final cause. If the iFob is not recognised, the unit will need to be returned.

Door won’t close

Possible Cause: Override mechanism left in open position, key bunches blocking door, failure of locking mechanism

Workaround: Ensure that the door override mechanism is in the closed position, and that none of the key bunches within the unit or any exterior item is blocking the door from closing fully.

USB not recognised

Possible Cause: USB drives not recognised by system

Workaround: Several options avialable

  • Memory stick should be FAT formatted for use in a Traka21
  • Larger capacity memory sticks (>8GB) may take 10 seconds or more to appear
  • Plug USB it into a desktop PC and see if the PC reports that the memory stick needs ‘Scanning and Fixing’ – it may have corrupt contents
  • Format the memory stick in a Windows PC and retrying in the Traka21 (note that this is a more advanced fix requiring experience of formatting a disk and erasing its contents)
  • If the memory stick contains a large number of files and folders, clear the memory stick and using it in the Traka21
  • Although a standard IT response, turn the unit off and back on again. If the USB driver has ‘hung’, then this may restart it and allow communication with the memory stick
  • Another memory stick, preferably a different type could be tried in the unit
Unable to delete Admin User

Scenario: When attempting to delete one of the admin users, an error message appears stating that all other non-admin users need to be delete first.

Workaround: If any of the admin user accounts are edited through the user interface, e.g. contact number is added, rather than the Export & Import feature, then the active date is then populated, allow for the admin users to be removed.

Traka21 is offline

Scenario: Your unit displays a message saying that your Traka21 is offline. Only administrators can get keys.

Workaround: If the battery on the device is critical, then it will not allow non-admin users to login. Ensure that your unit is connected to a mains power supply to recharge the back up battery and allow non-admin users to access the cabinet.

Non Traka21 iFob placed in cabinet

Possible Cause: Non Traka21 iFob placed into unit and connot be removed.

Workaround: The swap key positions feature is very beneficial if you wish to reorganise the keys in the system. You can also use this feature to remove a non Traka21 iFob from the cabinet if it has been placed there in error.

  1. Select the Swap Key Positions button from the key wizard menu. The swap key overview will then appear giving you a description of how the feature works. Read this and click the forward arrow.
  2. Select the position of the non Traka21 iFob. The iFob will then release to you, removing it from the system.
  3. Select the Exit button to return to the admin menu
