Aiphone JO-1MDW, can I add a door bell?

[beecee]

I have a aiphone intercom fitted to my front gate, which uses the JO-1MDW monitor, a JO-DV camera/intercom and a AI-AC10S keypad to open the gate. I would like to add a door bell so when somebody enters the code the door bell rings inside and I know the gate has been opened.

Can I use a unit like this:


If I just loop the gate open trigger wire through this door bell unit?

If your lock it 12v dc powered, yeah fine. Just any 12v dc buzzer / chime unit will be fine.
Just join it in with the power to the lock.
