Alarm system without e-mark WHAT NON?

Hello all, have a Fiat Punto HLX built in 2001 with ZV with remote control (button on the key) and immobilizer from WERK OFF. Now I have bought an alarm system called TRACK PRO TP-8800. But now I have to ask a few questions in advance. 1. this system has no e-test mark, what does that really mean now? I only know that it has something to do with interference and magnetic signals and more. Can I install this system now or not? A mechanic from the Bosch service m The system will not be built, since it does not have an e-test mark and it can be dangerous and sometimes when driving on the highway the immobiliser could just start or anything else. 2. Can I take and switch between the work instead of the immobiliser, so that I can activate the immobiliser at the push of a button and the Punto comes to the stand? 3. Can I connect the existing ZV to the alarm system and then via the pager de r Alarm system control the ZV? Thank you for your help and I would be very happy about experiences with the alarm system TP-8800
