Automatic doors

Bonjour

I try to re-use my 220v doors motors with
Arduino-mutiplex-8relay
I test with 220v light
The way I plug it works but only by "cutting" the circuit using
The "NC = Normally Closed Connection":
When the red light on the board is on the NC shut the light and when the red light is off the light is on.
When I plug on the NO the light never on
The only way to hear is to put dongle on the right
What I'm doing wrong?

Sorry I found the right way to plug in the relay
