If its a Zigbee device you have (sorry, dont know much about these devices) then you may be better to post here requesting a driver once you have searched the Wiki at the top of the post to ensure there is not a driver already available (and havn’t done this already).
With regards to this keypad, its all based on routines so you control what it does when you press arm/disarm and with the arm/disarm buttons, you just setup the routines from within the device itself.
Thinking forward, if you do go down the Ring route, you might want to install the driver manually, at least that way, you would be able to make code changes to get it functioning how you need it (if your that way inclined 
)
Finally, and I cant explain why as im on Android, but some users have said they get a restricted gui on IoS, its all discussed above and just something to watch.
