A couple of questions about the DSC alarm systems

Hi!

I have two questions about DSC alarms:

  1. Is it possible to disarm a zone through some kind of dry contacts interface?

Context: I have a myQ garage door opener, and I want to disarm the garage zone when the garage door is opened through it. I already have a dry contact interface with the opener, and all I need is to trigger the disarming.

  1. I have a hardwired DSC zone expander, how far can it be from the panel? Will it work if it’s 20 meters away? I want to use it as a multiplexer, instead of pulling 16 additional wires.
