Multiple Choice

For an orange head sprinkler, which activation temperature range is specified?

Explanation:
In sprinklers, the color of the head indicates its activation temperature. An orange head corresponds to an Ultra High rating, which activates at about 500–575°F. This higher temperature rating is chosen for environments where you want the head to remain closed until a very intense heat source is present, reducing nuisance activations. The other ranges are associated with different color-coded ratings and do not match the orange head's specification.
