What is a water motor gong?

• A. An audible alarm indicating alarm activation
• B. A cooling unit for the sprinkler system
• C. A component that controls water flow
• D. A manual activation switch for the system

Answer: (A)

A water motor gong is designed as an audible alarm that activates when there is an alarm condition in a fire sprinkler system. When water flows through the system due to a sprinkler head activation or a pipe rupture, the movement of the water turns the motor of the gong, producing a loud sound that alerts occupants and responds to the alarm condition. This feature is critical for warning individuals in a building or area of a potential fire, thereby facilitating timely evacuation and response. The other options do not characterize the function of a water motor gong. The cooling unit for the sprinkler system does not relate to alarms; a component that controls water flow pertains to valves or flow switches rather than alarms; and a manual activation switch is a different mechanism used to initiate the sprinkler system manually, which is distinct from the automatic alarm functions provided by the water motor gong. Understanding the role of each component in a fire protection system helps ensure proper maintenance and use during emergencies.
