Linking Marmitek SC9000 alarm panel

[nfaber]

I'm having some troubles connecting my SC9000 with the RFXtrx433E.
I would like to set up two-way communication:
1) Domoticz --> SC9000 for putting the alarm panel in arm / disarm state when my Domoticz alarm is turned on (by app or remote)
2) SC9000 --> Domoticz for being able to arm and disarm my Domoticz alarm using the panel/keypad

In my case Domoticz is connected to all my sensors (433 MHz+Z-wave), my SC9000 panel has no devices and is only used as a user interface.
For handling situation 1) I made the Rfxcom send signals similar to a KR21 keyfob, which works fine.

The problem is that i cannot receive any signals from the SC9000 when it is being armed or disarmed.
According to section 10.5 of the manual (See http://www.haibrain.com/documents/downl ... 000_EN.pdf, warning: directing to download) the SC9000 is capable of switching external indicator lights when armed, however i cannot receive these.
I manually added X10 devices on address A1, A2 and B1 in domoticz, but these are never triggered by the alarm panel.
Does anyone have suggestions?

Ths SC9000 transmits commands over the power line and not as RF.
