At what temp sprinkler system operates?

Sprinkler systems typically activate at temperatures ranging from 155°F to 200°F (68°C to 93°C), depending on the specific type of sprinkler head used. Standard temperature ratings include 155°F, 175°F, and 200°F. Once the ambient temperature at the sprinkler head reaches its activation point, the heat-sensitive element responds, allowing water to flow and suppress the fire.
