To meet code here with earthquakes and all we had to have fire sprinklers installed throughout our house. We had these done by JFK Fire Sprinklers and John did a great job, showing up on schedule and finishing in about 3 days. Here is a photo of one of the heads that sits above the sheet rock. The head will be flush with the sheet rock. When there is a fire, only the sprinler heads in that particular room or area are activated by the heat, popping down and water flowing out. Fortunately that would avoid sprinklers going off all over the house! Every room and hallway got them, even the larger closets.
