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)

40c is miserable to be in, but it's not really that hot compared to fire or combustion. The record hot day in Phoenix was 50c; miserable but livable w/ precautions.

wet pipe burst temps are between 57c-75c .

While 40°C is hot, it is not insanely hot. Every summer temp goes easily above 35°C in my apartment for a number of days.

40C is not comfortable, but it's pretty normal summer weather in many parts of the world.

So pretty much room temperature in central Europe in summer?

there’s different types of sprinklers which can be used in different settings. :)

And actually i misspoke on the 40C! I mixed up that number with something else so that’s my bad. It actually activates around 60C-70C depending on the make/model.
