Eurotec Freewave 868 Mhz on RFLink

[Daylights]

I'm using a 433Mhz RFLink which works great. I have an old Eurotec C6.6 alarm system laying around with multiple magnetic contacts, PIR's and smoke sensors. I've opened the central housing and a FreeWave 868.35Mhz (TDA5210) receiver was to be found in there. Is there any luck I might be able to use the 868Mhz sensors with an 868Mhz RFLink? Or will these sensors probably be protected by the manufacturer?

Did you ever found an answer for this?
I also have the same Eurotec unit and sensors and would like to connect them to Domoticz.
