Compatibility of Yale alarms and Digital Voice service

[sharpener]

As title, I looked on the Yale support web site, you would think there would be some info but nada.

 

So I enquired via the comment facility but have not had a reply, and judging from previous useless experience don't reallly expect one.

 

Hence I am assuming my HSA 3000(?) series alarm's central control box will require upgrading to something new with an internet connection.

 

Can anyone tell me if their current offerings are backwards compatible with all the sensors in the house which use 433.92 MHz AM signalling, or am I going to have to change them all as well?
