THITRONIK® NFC Module Operating Instructions

The NFC module is an accessory for the THITRONIK® alarm systems, which allows to control the camper with an NFC tag, an NFC key card or a compatible* credit card contactless and to arm and disarm the alarm system silently. The NFC module comes with a key card already taught.

The NFC module is easy to install without tools. It is attached to the window pane with the supplied adhesive pad and tuned in to the alarm control panel via radio. No drilling or laying of cables is required.

* The credit card requires a static ID - you will not receive this information from your credit card company or Thitronik. Follow chapter 5 and test your credit card.



1.0 Compatibility

The NFC module can be used with the THITRONIK® alarm systems WiPro III, WiPro III safe.lock, WiPro easy and C.A.S III. With the WiPro III safe.lock you can not only arm and disarm the alarm system, but also lock and unlock the doors.


2.0 Commissioning

  1. Remove the battery fuse Before you can use the NFC module, you have to remove the battery fuse. To do this, pull the tab out of the housing.

  2. Start the learning mode of the alarm control panel Now connect the NFC module with your alarm control panel. Start the learning mode of the alarm control panel. The instructions for starting the teach-in mode of the WiPro III are explained in these videos. How to start the teach-in mode on the WiPro easy can be found in the WiPro easy user manual.


    Important note

    The NFC module must not be tuned in to the WiPro as the first accessory component, as it is recognized as a master radio hand-held transmitter. It is necessary to first teach a normal radio hand-held transmitter to the WiPro in order to ensure the correct functioning of the system.

  3. Trigger NFC module Now trigger the NFC module with the supplied key card by holding the card to the NFC module. The WiPro III will acknowledge the successful pairing process with a tone. With the WiPro easy, the successful pairing process is signaled by the LED on the control panel lighting up.

  4. End the learning mode of the alarm control panel End the learning process of the alarm control panel as described in the respective manual in step 2.

  5. Mounting Mount the NFC module on a suitable place after cleaning the surface. Remove the two adhesive surfaces on the back of the device and place it at a suitable location inside your motorhome. We recommend using the front window, a side window or the window of the body door. Make sure the module is easily accessible to allow for future maintenance, such as battery replacement. The maximum distance to the NFC tag should not exceed 20mm. The NFC module is now ready for operation.

3.0 Operation

To lock and unlock the motorhome, you can now simply hold the already taught key card to the NFC module. The module recognizes the card and sends a signal to the WiPro III alarm center, which then switches to the next logical state. Please note that between each triggering of the NFC module with an NFC tag, at least 2 seconds must pass to avoid operating errors.


4.0 LED states

The LED in the NFC module visualizes the different operating states. The following table lists the operating states to be visualized with the corresponding LED state.


LED state

Teach-in mode

Blue LED is permanently on

Teach-in mode active

5.0 Teaching additional NFC tags


In order to teach in further NFC tags, the housing of the module must be opened. To do this, turn the housing cover to the left and remove it. Press the button and keep it pressed for at least 3 seconds until the LED lights up solid blue. The NFC module is now ready to enroll additional NFC tags. Hold the new NFC tag to the device. The NFC module acknowledges the successful enrollment process by flashing the LED. Note that if the LED flashes twice, it means that the tag is encrypted and secure. If the LED flashes only once, it means that the NFC tag works but is insecure. We recommend you to use only the encrypted THITRONIK tags. After you have learned all further tags, you can end the learning mode by pressing the button again. The blue LED goes out. Then close the housing cover by aligning it with the LED recess on the transparent recess and turning it to the left. Make sure that the casing lid is securely closed to ensure proper function of the NFC module.


6.0 Compatible NFC tags

The NFC module supports up to 14 NFC tags. We recommend using only THITRONIK® NFC tags to guarantee a secure system. Other NFC tags without the THITRONIK® security standard can easily be copied and give access to the alarm system and open the vehicle. When an unsecure NFC tag is learned, the NFC module will indicate this by flashing once. When enrolling and using a secure THITRONIK® NFC tag, the module will flash twice.

The meaning of the blink codes of the NFC module can be seen in the table above.


Note: Please note that our KeyStrap is most effective and secure when used on glass panes. Please note that due to the thickness, some types of plastic windows (often double-walled) are not suitable for use with our KeyStrap. See technical data for more information.


7.0 Deleting the taught-in NFC tags

To delete taught-in NFC tags, you must press and hold the button for at least 10 seconds. As soon as the blue LED starts flashing fast, this means that the deletion process has been completed successfully. Release the button, the blue LED will now be solid and the NFC module will automatically be in teach-in mode again. Now you can re-learn the NFC tags you want. It is important to note that when deleting the taught-in NFC tags, all stored tags are removed and it is not possible to select and delete individual tags.


8.0 Changing the batteries

To change the batteries of the NFC module, you first have to open the case. To do so, turn the case cover to the left and pull it towards you. Inside the case you will find the battery holder. Take out the empty batteries. Now insert the new batteries (alkaline (LR03) AAA) into the holder, making sure that the polarity is correct. Close the case by turning the cover back to the right.

It is important to note that you only use alkaline (LR03) AAA batteries. If you use other types of batteries, the NFC module may malfunction. After changing the batteries, the already learned NFC tags do not have to be learned again, they can still be used.

We strongly recommend an annual battery change to ensure the proper function of the NFC module. If you use your vehicle also in winter, then we recommend the battery change shortly before the cold season.

The NFC module may only be used for wireless control of THITRONIK® alarm systems. Any other use, in particular the use for other technical applications, is prohibited and may result in damage to the product as well as danger to persons and property. The manufacturer accepts no liability for damage caused by improper use of the NFC module.
