Fire pumps shall be supervised for which supervisory signal?

Fire pumps shall be supervised for which supervisory signal?

• A. Pump running - supervisory signal
• B. Power loss - supervisory signal
• C. Tank level - supervisory signal
• D. Alarm bell - supervisory signal

Answer: (A)

The essential idea is that equipment critical to fire protection must be continuously monitored to confirm it’s functioning when needed. For fire pumps, the status that the system must supervise is whether the pump is actually running. This allows the fire alarm control panel to detect if the pump fails to start or stops during a fire, and to raise a trouble/supervisory signal so responders know there’s a potential pump failure. Other options don’t fit because power loss refers to power availability rather than the pump’s running status, tank level isn’t typically a monitored parameter for a fire pump in this context, and an alarm bell is an output device, not the supervisory input that confirms the pump’s operation.
