What is the color code for heat detectors when the ceiling's maximum temperature rating is 305°F?

Explanation:
Heat detectors are matched to ceiling temperature ratings using color coding so installers can quickly pick a device that can tolerate the ceiling’s heat. Red is used to denote the highest fixed-temperature detectors, around 300°F. Since the ceiling in this scenario can reach about 305°F, the detector chosen needs that higher rating, so red-coded heat detectors are the appropriate choice. The other colors (blue, yellow, green) indicate lower fixed-temperature ratings, which wouldn’t meet the 305°F ceiling requirement.
