Question Yale (not smart) alarm integration

[arachnoid]

I have a Yale alarm system based on a HSA3400 and other Yale components. Not a current product but it does the job OK. There is a phone line output so the system can dial a phone in case the alarm is activated. Would there be a fairly easy way to take that signal output and input it into a home automation system (Openhab2/Z-wave/Pi)?
