Interface Hardwired Security System Sensors with Wireless Door Sensor

I’ve spent the last hour reading through posts on this forum related to using an existing hard wired system but couldn’t find anything super helpful.

I have a hardwired home security system (Networx NX-6v2) that I would like to connect zones to a Z-wave door/window sensor (either the Ecolink or Monoprice). Both have external switch terminals on the board. I would like to continue using the existing system/panel, I just want to take advantage of the notifications when the reed switch for a zone is flipped.

I found this post ( which sounds like exactly what I want to do, except that application is for smoke detectors. Just the window/door reed switches that are already installed. Would the same concept of using a relay apply here? Or is there another simpler method that I’m overlooking?
