What is the purpose of an alarm initiating device in NFPA 20 fire pump systems?

• A. To alert building personnel or the fire alarm system when the pump starts, stops, or fails.
• B. To automatically start the pump under all conditions.
• C. To measure discharge flow.
• D. To regulate valve positions.

Answer: (A)

An alarm initiating device in NFPA 20 is there to provide immediate notification of the fire pump’s status to building personnel and the fire alarm system. When the pump starts, stops, or fails to start, this device sends a signal to the control panel or fire alarm system so occupants and responders are alerted and actions can be taken promptly. It is a signaling device that enhances situational awareness and coordination with the building’s fire alarm, not a control that starts the pump, regulates valves, or measures discharge flow.
