Window contact

[eulaersi]

I've installed two window contacts at each window: one for my alarm, and one to be read by EIB.

But because I've used contacts that were delivered by the alarm expert, I now have contacts that return 4.6 ohm when closed, and 9.1 ohm when opened.

What is the easiest way to read those contacts with my EIB system?

Thanks,

Ivan
