Automatic fire sprinklers utilizing frangible bulbs follow a standardized color-coding convention indicating their operating temperature. Activation temperatures correspond to the type of hazard against which the sprinkler system protects. Residential occupancies are provided with a special type of fast response sprinkler with the unique goal of life safety (a residential sprinkler has a higher discharge pattern than that of a standard spray sprinkler and they also have been specifically developed for discharging water higher on the walls in order to keep ceiling gas temperatures lower).
