How are sprinkler heads categorized?

Sprinkler heads are categorized primarily by their release mechanism and mounting position because these factors significantly influence their operation and effectiveness in delivering water to a fire situation.

Release mechanisms refer to how the sprinkler head activates when a fire is detected. Common types include fusible links, glass bulbs filled with liquid that shatter at a specific temperature, or other heat-sensitive mechanisms. Understanding the release mechanism is crucial since it determines the temperature at which the sprinkler will activate and the speed of response to a fire.

Mounting position categories include pendent, upright, sidewall, and concealed, among others. This classification accounts for where and how the sprinkler heads are installed in a building, which affects their coverage area and water distribution patterns. Choosing the appropriate type for the specific location is essential for maximizing fire suppression capabilities.

While aspects like brand, model, color, size, flow rate, or pressure can be relevant to discussing sprinkler heads, the primary categorization that impacts functionality and application falls under the release mechanism and mounting position.
