Every commerical building I've ever seen has fire alarm levers on the walls. Somebody could have triggered the alarm manually.
These fire alarm levers are everywhere, but they rarely ever get used in an emergency. If what happened is someone pulled the lever and the system logged it but the alarm didn't go off, that's a huge problem.

I see these very rarely nowadays.
Apparently they get triggered too often as pranks, and it trains people to ignore the alarms. So, they don't put them in new construction.

There was a linked paywalled article, the link text seems to indicate that alarm logs show the alarm was triggered. Not sure by what, maybe the article has details. I wouldn't expect some sort of collapse sensor in the fire alarm system, but when the pool deck collapsed, it may have released enough dust to trigger a smoke detector in the parking garage, or it may have disconnected sensors which could also be a triggering condition.
