What is the primary function of a high temperature head in a fire sprinkler system?

The primary function of a high temperature head in a fire sprinkler system is to withstand higher ambient temperatures. High temperature sprinkler heads are specifically designed to operate effectively in environments where temperatures exceed the standard levels, typically reaching close to 200°F (93°C) or more, depending on the classification of the sprinkler head. This characteristic is essential in applications such as industrial settings, warehouses, or areas where manufacturing processes may generate significant heat.

A high temperature head ensures that the sprinkler will not inadvertently activate due to ambient heat that is higher than usual, thereby preventing false activations that could lead to unnecessary water discharge. This functionality is crucial in maintaining safety and minimizing water damage in environments where elevated temperatures are part of normal operations.
