let me help educate you. :)
Most common sprinkler type used in a residential setting is “wet pipe”: https://www.nfpa.org/news-blogs-and-articles/blogs/2021/03/2...
The sprinkler is “activated” if the ambient temperature around the sprinkler head is 40C, due to the little “wet pipe” in the sprinkler bursting. 40C is HOT. Basically - when your whole apartment is beginning to catch fire. It’s designed to save lives, not your things.
Newer (higher end) apartments will have the sprinkler itself hidden / recessed, this way the little wet pipe / vial can’t be accidentally damaged by force (when cleaning, painting, etc)
