Fusible type sprinkler heads consist of several components. Which of the following is NOT one of them?

• A. Frame
• B. Levers
• C. Cap
• D. Gauge

Answer: (D)

Fusible type sprinkler heads are designed to operate based on a specific temperature activation mechanism, typically using a fusible link that melts when a certain heat threshold is reached. The primary components of these sprinkler heads include a frame, levers, and a cap. The frame serves as the structural support for the sprinkler head and houses the other components. The levers are part of the activation mechanism that opens the sprinkler when the fusible element melts. The cap is a protective component that covers and seals the sprinkler head until activation. The gauge, however, is not a component of the fusible type sprinkler head itself; it is used in conjunction with system monitoring and maintenance to assess water pressure within the standpipe system. Therefore, it is accurately identified as not being a component of fusible type sprinkler heads.
