To provide more information than the others who responded: typical sprinkler systems are not automatically activated in response to a fire alarm. Each sprinkler head has a small glass vial filled with a liquid, calibrated to break at a certain elevated temperature (e.g 160 or 180 F). The flow of water starts when the glass breaks. So there has to be a significant fire near the sprinkler before it activates.

One weakness is that the glass vial is fragile. In some hotels you’ll see signs reminding guests not to hang clothes from the sprinkler head, as a clothes hanger could break the vial and activate the water flow.

"By accident"? How do you think sprinklers work, exactly? You "accidentally" left the sauna door open and now the living room is 160F?

If it were a problem, you'd be hearing about it from apartment dwellers, since sprinklers are required in many (if not most) cases:

Worse yet, you might not have a choice; the article notes that “sprinklers are already required in all new California homes built in 2011 and later.”

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)

It's kind of funny that everyone's crapping on this comment when the poor value proposition of sprinklers in residential settings is exactly what enabled the investment to develop this system.

I use to worry about this but the industry claims about 1 per 20 million accidental discharge per year, which over the lifespan of a home works out to be 10-1000x less than other common hazards (including fire).

Please enlighten us then, why do many countries require commercial kitchens have fire sprinklers if it's such a terrible and dangerous idea?

That's not how sprinklers work?

Have you ever lived in a place with sprinklers?

Do you actually think they go off when ever the highly sensitive smoke detectors detect you made your pizza extra crispy with the window closed.
