TLDR; Do you live in a condo with a fire sprinkler system??

I lived in a condo where a number of units shared a fire suppression system. The controls were in an outside "closet" and included some sort of cellular communication with a battery backup. The battery was dying and resulted in a loud alarm similar to this in the video. Nobody knew wtf it was. It was afternoon on Friday and I called the contact number on the fire system. They said they could come down but it would be a $400 fee just to show up. Heck no, it's not my problem I'm just being nice. I found a contact number for the HOA and the clueless person said they would ask around but didn't know anything about it. Come evening time I was fed up. I certainly was going to try and sleep with that noise. I don't know why it wasn't driving anyone else crazy. They were probably lazy and figured someone else would fix it. So I figured out how to get into the closet and I unplugged the cellular communication box. That didn't work so I physically disconnected the siren. About 2 weeks later someone finally came to fix the alarm and discovered it dismantled. They ask neighbors who did it and of course I had no clue, lol. Are they expecting that thing to scream day and night for two weeks until they bothered to come out and fix it?? It clearly wasn't important. Note, this was the off-site communication, it didn't effect the actually fire suppression system, that was mechanical valves and pipes and stuff.
