Elk M1G Doorbell Zone Question..

[Serge5757]

I think I got it. Mainboard input array should have Address 1 on Bus Type 2. All extensions on the same bus, 2 and up, right?

 

[Serge5757]

Reenrolled it to address 2. Working now!
Thank You very much Gentlemen.

Check your documents. The devices come with them for a reason. Addressing is a function of the zone numbers you wish to assign to the expander in question.
