NFC Code Touch Air

The Loxone NFC Code Touch Air is used for access control and features an NFC reader and illuminated keypad on a glass surface.

Access control solution via NFC tags, available as key fobs, stickers or cards. Alternatively, a numeric code can be entered on the keypad.

Combining an NFC tag and a numeric code enables two-factor authentication. The keypad also features a freely programmable doorbell button and a tick button to confirm entries.

The device can be operated either with an external power supply or with two AAA batteries.
In battery operation, the permanent keypad illumination and the controllable status LEDs are not available. These are only activated for a short time when the device is operated.

Fasten the included plastic mounting frame to a flat surface or to a 68mm installation box.

A junction box is highly recommended when using an external power supply, as it makes it much easier to tuck away connecting wires or a spare loop behind the device.
Optionally, a small power supply unit can be installed in the box.

The NFC Code Touch can also be mounted using the single or double aluminium frame, available separately. We recommend the NFC Code Touch Tree in combination with the Intercom.

Connect the power supply (orange/white plug-in terminal).
For battery operation, remove the orange/white plug-in terminal and insert two AAA batteries.

The self-adhesive cover protects the battery compartment against splash water and must not be removed.

The NFC Code Touch is first inserted into the top of the frame and then snapped into place at the bottom. To release the device, pull firmly on the bottom to disengage the latch.

A suction cup can be used to detach the device from the aluminium frame.


In delivery state, pairing mode will be active after the power supply has been established. This is indicated by the right status LED flashing red/green/orange.

Then follow the pairing procedure

To activate the pairing mode manually, switch off the power for 10 seconds, then switch it back on. If no connection to a Miniserver can be established for two minutes, pairing mode will be activated for a limited time.

The available functions differ depending on whether the device is battery operated or connected to an external power supply. This is determined during pairing. The device must therefore be paired in the same supply method in which it is to be operated later.
If the supply method is changed later, the device must be deleted from the configuration and paired again.


The device is configured and set up using the Authentication NFC Code Touch function block in Loxone Config.
Drag the NFC Code Touch from the periphery tree to the configuration page to create the function block.


In order to gain access to a building, a paired NFC tag is held up to the NFC reader on the device. The tag is read and authorisation is verified.

In order to authenticate using an access code, enter the numeric code on the keypad, followed by the 'tick'.

If the authorisation was successful, access is granted and the status LEDs light up green. As an example, the door can then be unlocked. If access is denied, the LEDs light up red.

Additional functions can be selected by entering a prefix.
To do so, first enter the prefix number set in the configuration and then hold the NFC tag up to the reader.
When using a code, first enter the prefix, then confirm with the 'tick', followed by the access code.
After successful authorisation, the function assigned to the prefix is activated.

Too many failed attempts by an unauthorised NFC tag or numeric code will result in the keypad being locked for 2 minutes. An authorised NFC tag can unlock the device before that time.

Configuration also allows you to limit access via NFC tag or code to specific times, or set them up for one-time use.

More information can be found in the documentation of the Authentication NFC Code Touch function block.

Water on the surface of the NFC Code Touch can interfere with its operation. After the surface dries, the NFC Code Touch automatically re-calibrates and operates as usual.

LED states

A row of four LEDs at the top of the device actives during operation, and also indicates whether access was granted or denied.
The following table shows the possible LED states:

LED display Meaning
4x white, counting down Indicates the timeout after a digit was pressed. The next digit must be entered within this time.
After the time has elapsed, the entered code is checked for authorisation.
4x green, fading out Access granted or confirmation for bell button.
In NFC learning mode: Tag was successfully detected
4x red, fading out Access denied, tag or code invalid, or not authorised.
4x red, flashing fast, counts down slowly Device is locked after repeated use of an unauthorised NFC tag or code, or by the reset input of the function block.
4x cyan, running light from left to right NFC learning mode is active.
4x yellow, flashing Error while reading NFC tag in learning mode. Try again, hold tag steady! The NFC monitor provides information on the cause of the error.
Individual The 4 status LEDs can be controlled together via configuration and display the primary colours. They are only displayed if no other status is currently active.
Only right LED active Indicates the LED status of this Air device.

Battery Replacement

To replace the batteries, remove the NFC Code Touch Air from the mounting frame. Remove both AAA batteries from the compartment on the back and insert new ones, observing correct polarity.
The device then restarts and the right status LED flashes green three times, indicating that the connection to the Miniserver has been established.
In case the LED does not blink at all or is permanently (faintly) red, the batteries are empty.

Safety Instructions

When connecting to an external power supply, the installation must be carried out by a qualified technician in accordance with all applicable regulations.

Follow the installation instructions closely to guarantee protection against contact, water and dust.

The device must not be used as part of safety-critical systems.

For security reasons we strongly recommend that you only use encrypted NFC tags from Loxone for access control.
