Sprinklers are highly reliable devices that are activated by heat. They will only go off if there is a fire which increases the heat beyond the sprinkler trigger point (typically 135 to 165°F (57.2 to 73.9°C)). “When a fire occurs, every sprinkler head goes off.” Sprinkler heads are individually activated by fire.
