A technical error may occur in individual CarPro-Tec Fusion 4G devices that were delivered between 17 March 2025 and 4 May 2025.
The error:
The system can ‘freeze’ after some time in the armed state.
This means that
- Control via app or remote control no longer works.
- Sensors (e.g. door contacts) and room volume sensor no longer trigger an alarm.
- The GPS signal is still partially transmitted, which makes detection more difficult.
Self-test
To check whether your CarPro-Tec is affected, please carry out the following 4-day test:
- Set the sensitivity of the room volume sensor to 0%.
- Leave your CarPro-Tec armed for 4 days.
- No alarm should be triggered in between.
- After this time, please check:
- Can the device be disarmed via the app or remote control?
- Does the system respond to triggered sensors (e.g. open window contact)?
❗ If neither is the case, the error mentioned is most likely present.
Procedure
In this case, please create a ticket. (Create ticket) and indicate in the description that you have carried out the 4-day test and your CarPro-Tec has frozen.
We will then take care of a quick replacement of your device under warranty.
Note:
The error can be rectified temporarily by doing the following:
- Switch the device off completely using the SYSTEM button (not the 4G button).
- Then switch the system on again.
The device will then work normally again.
