For lighting hazard occupancies such as office buildings, what is the standard temperature range for sprinkler heads?

Activation temperature of sprinkler heads is the heat level at which the head will release water. In lighting hazard occupancies like offices, you want heads that respond to real fire heat but aren’t triggered by normal room conditions. The standard range used is 135°F to 165°F. Heads rated at the lower end (around 135°F) respond quickly in typical office environments, while those rated up to 165°F are suitable for areas that may experience higher ambient heat (near sunlit windows, hot equipment, or strong lighting) to prevent nuisance discharges. This combination covers the common conditions found in offices, making 135–165°F the standard range.
