Which sign requirement applies to valves in sprinkler systems?

• A. Weatherproof identification signs.
• B. No identification required.
• C. Digital display labels.
• D. Plastic name tags.

Answer: (A)

Valves in sprinkler systems must be clearly identified with durable, weatherproof signs. This visibility is essential so anyone operating or servicing the system can quickly locate the valve and understand its function, especially in an emergency. The signs need to withstand moisture, weather, and wear, which is why weatherproof signs are specified rather than casual placards or digital labels. In practice, signs indicate what valve is controlling the water supply (for example, main valve, zone valve) and are placed where they are easily seen near the valve, often referencing the corresponding system drawings. Other options—no identification, digital displays, or plastic name tags—don’t meet the standard requirement for durable weatherproof identification.
