Does commercial fire alarm system go down when Internet is out?

I live in an apartment building that was an old high school. The Property Management company cut off our Internet, even tho it’s included in our Lease Contract. Another issue. Sigh.

The building was renovated in 2019/2020. Every apartment is wired for cable and Internet and the common areas - hallways, community room, fitness room - have hard-wired Fire Alarms🚨 . Does a hard-wired, building-wide system communicate with the city FD via Internet if an alarm is triggered? If so, because the company cut off Internet access, it would seem the building’s fire safety system is not working. We are a Section 42 complex, meaning govt funding. Should I contact our local FD?
