Discussion Questions
21

Did you tried the blue wire(open) into the clamp

22

The orange wire should be in the R2

23

2 black wires to plug

24

Thanks for commenting.

I don’t think I have tried that.

Do you have this working?

25

Normally you can,open the door automatically with an option cable. Aiphone do it for your model.

I have the aiphone :GT-1C7-L

Actually I didn’t tried yet with the nuki device but according to the wires without nuki installation.

I just need 4 wires in the standard installation :
Blue : B1 -RING AND OPEN
Transparent : B2-video
Yellow : R1 - AUDIO
ORANGE: R2 MICROPHONE

Leave the original wiring, as it was before you were

The Opener.

  1. Connect the black wire of the Opener (in addition to the installation wire) to location b (“Bus-”), and the red wire of the Opener (in addition to the installation wire) to the location

A (Bus+).

Do not make any other changes. Do not remove any wires or use the other threads of the Opener or the terminal block you received with your Opener.

Version 1

Remove the BUS cable (1) and

Connect it with the yellow wire and

Red of the Opener in the terminal block

Supplied with the device.

Then place the orange and green wire

From the Opener in the port now

Free of the system.

The cable that is in BUS (2)

Stay connected. Just add to it

The black thread of the Opener.

Hi, I also have a GT-1M3. Someone here who tried the above solution? I have not yet bought the opener because I’m not sure it will work with our Aiphone model.

Bonjour
Quelque un à t il testé cela (aiphone gt1D avec opener) ?
Merci vienn

30

No success yet?

31

Still no success? Thank you

32

Sadly, no
 I still haven’t bought the Opener because I’m unsure if it will ever work for the GT-1M3. I don’t even know how to open the intercom to be honest :smiley:

Hello
While I don’t own any Nuki products, I came across this thread while searching for how to automate the Aiphone GT-1M3-L. My setup matches the original poster’s configuration where only the IN ports are used on the resident station, with OUT ports unpopulated.

Looking through the installation documentation for the GT line of intercom from Aiphone, I discovered several compatible resident stations that share the same system:

  • GT-1C(-L)
  • GT-1C7(-L)
  • GT-2C(-L)
  • GT-2H(-L)
  • GT-1M(-L)
  • GT-1M3(-L)
  • GT-1D
  • GT-1A
    (Note: The -L suffix indicates hearing aid support)

The documentation also clearly labels the different ports:

  • B1 & B2 IN: Video stream input to the station
  • C & CE: Doorbell outside the apartment’s front door (not connected to the Aiphone bus system). This only rings the bell on the resident station without triggering video or audio on the station, typically connected to a third-party doorbell
  • K & KE: Emergency alarm switch (I think North America only?), on my station it’s just shorted like in the original post
  • R1 & R2 IN: Main communication ports handling:
    1. Audio between residential and outside stations
    2. Ring signal that activates residential stations
    3. Door unlock commands from residential station

Based on this it appears that R1 and R2 IN are the only ports needed to unlock the front door. While I can’t speak for the Nuki Opener, I have successfully managed to remotely unlock my apartment’s front door using these ports. One important limitation is the Aiphone GT system doesn’t respond to the unlock signal unless the resident station has been activated first (someone needs to ring before the door can be unlocked). I’m hoping to automate geofencing with ring-to-open using Home Assistant.

Hope this technical information helps those trying to get the GT-1M3-L to work with the Nuki Opener. Perhaps the Nuki developers can provide additional insights based on this information.
