Hi,

I have Urmet 1705/90 video door phone and trying to find is there instructions on installation I can look at before buying the Opener?

I have attached the image below and advice would be appreciated.

Looks analogue, so no issue! Ca is the call wire, this would be for ring detection, and you have now just to find the 2 wires for gnd and opening (buzzer), I am really sure gnd is 6, so you just have to find the one opening (buzzer) wire!
