Security Panel using Wayne Dalton Wireless Keyless Entry?

I don’t own these so I’m looking for people that do or have used them.

My thought is maybe would could make a Security Access Panel using a Wayne-Dalton KEP-IV Wireless Keyless Entry

say it requires a Wayne-Dalton WDHA-12R HomeSettings Wireless Gateway, not sure if it really does.
