Ge010- How It Can Test?

[elkesan]

Dear friends,

How I can test Terraneo (Bticino) GE010 unit?

This unit is electronic device for lean line. (Lean line = 1+n)

I install 12 VAC to T andsS. I install one phone, and call work. Only installations I have is phone and 12 VAC.

But- when push door open switch, nothing happened. (Short circuit of the line.)

How I can test GE010?

Maybe I must install 2660 amplifier unit, but- of course I haven't it on stock. I am not sure, but GE010 and 2660 is not-on-manufacturation today. (If anybody have 2660, even non-working, please tell!).

So: how I can test GE010?
