Eura ADP12A3 Intercom and AC30C7 Keypad Wiring for Electromagnetic Lock Control

Connecting the intercom itself is not a problem, according to the diagram (variant 1) it is child's play, but attaching the keypad to the kit proved difficult.

I wanted to connect the keypad's power supply to pins 2 and 4 of the intercom (power and ground), but it turned out that there is no voltage there all the time, only when the intercom is triggered. I connected it to a separate power supply and it is ok. I programmed the keypad and started to connect the electromagnetic lock, which, if not connected, is locked all the time.

Test 1

I connected the blue and purple cables of the keypad to the lock. It did not work.

Attempt 2

I connected the keypad's blue and purple cables to pins 5 and 6 of the intercom's external cassette. Did not work.

Attempt 3

I connected the keypad's blue and violet cables to contacts 3 and 2 (ground) of the intercom. Did not work.



Please help. My logic has failed me, and my knowledge is too little, or I am not patient enough.

Is it even possible to pair these devices?

Kind regards

Already got the subject under control. I was hoping that the power to the deadbolt would go through the intercom, as the intercom itself gives voltage to the deadbolt. You can't trigger the voltage to the deadbolt from the intercom by connecting the keypad to the intercom.
I simply had to let the power go to the deadbolt separately and connect the NO1 and COM1 outputs from the keypad directly to the deadbolt.
Simple.
Regards.

but do you have a diagram of how you put it together?
i'm putting together the same kit.... - i'm sitting on the wires and I've had a bit of a go
