What is the temperature range for high temperature sprinkler heads?

High temperature sprinkler heads are designed to activate at specific temperatures to ensure fire safety in environments where temperatures may elevate considerably. The correct temperature range for high temperature sprinkler heads is between 400-475°F. This range is particularly important in settings such as factories or warehouses, where the potential for high heat exists due to operational processes or materials stored.

High temperature sprinkler heads are crucial because they provide effective fire protection without being triggered by incidental high temperatures typical in many industrial environments. They allow for a tailored response to actual fire conditions, avoiding unnecessary activation and water damage from false alarms.

In understanding the other choices, the lower ranges (250-300°F and 325-375°F) pertain to standard or intermediate temperature sprinkler heads, which are suitable for more typical environments like office buildings or residential settings. The upper range (500-575 or 650+°F) is indicative of very high temperature sprinkler heads, which are designed for extreme conditions often found in specific industrial applications but are not classified under the standard high temperature category. This distinction is important when selecting and implementing fire protection systems in various settings.
