Non-automatic sprinkler systems are identified by bands of which color?

• A. Black
• B. White
• C. Blue
• D. Aluminum

Answer: (D)

Color bands on sprinkler system components help responders quickly tell whether the system will operate automatically or requires manual action. Non-automatic sprinkler systems rely on someone manually opening a valve or taking action to release water, so they must be clearly marked to distinguish them from automatic systems that activate by sprinkler head temperature. The aluminum color band is used because it provides a distinct, durable, and highly visible cue on typical metal piping found in bulk oil facilities, and it holds up well in oily, dusty environments. This makes it easy to recognize at a glance that the system requires manual operation, reducing confusion during emergencies. Other colors tend to be less distinctive or associated with different services, so they don’t convey the needed clear distinction as effectively.
