How can the temperature ratings of sprinklers be identified?

The temperature ratings of sprinklers are identified by color-coded sprinkler frame arms. This system of color coding provides a simple and effective way to communicate the operating temperature for different types of sprinklers. Each color corresponds to a specific temperature rating, allowing firefighting and safety personnel to quickly assess the design and intended activation point of the sprinkler during an emergency or inspection.

Color coding is a widely adopted standard within the industry, making it easier for users to ensure that they have the correct type of sprinkler installed for the environment. This visual identification method is crucial because the effectiveness of a sprinkler system greatly depends on the timely activation of the sprinklers at the appropriate temperature, which is indicated by these colors.

Other methods, such as numeric codes or heat sensor technology, may exist, but they are not as universally recognized or straightforward as the color-coded system. The type of water used in the system does not affect the temperature rating of the sprinkler itself and does not provide a means of identifying the temperature at which the sprinkler will activate.
