Which vertical pipe carries water above ground for fire protection systems such as standpipes or sprinkler risers?

• A. Sprinkler
• B. Riser
• C. Thermocouple
• D. Fusible Link

Answer: (B)

In fire protection systems, the vertical pipe that carries water upward to serve sprinklers or standpipes on upper floors is called the riser. The riser acts as the main water-bearing spine of the system, delivering water from the building’s supply (or fire pump) up through the floors to the outlets. Sprinklers are the individual heads that release water, a thermocouple is a heat-sensing device, and a fusible link is a heat-activated element that can trigger a valve—none of these are the vertical water-carrying conduit.
