You can have two types of wireless receivers connected to the M1. If you go that route, it won't obsolete all your existing wireless gear.
Elk doesn't recommend it because it makes configuration a bit more complex. The Elk two-way wireless receiver needs to be configured at address 2. So if you already have something else at that address, it will require changing zone assignments around.
