What type of signal would be generated at the FACP if the fire pump that feeds the sprinkler system is running?

• A. Alarm
• B. Supervisory
• C. Trouble
• D. Alarm and supervisory

Answer: (B)

When a fire pump that feeds the sprinkler system starts, it changes the status of equipment in the system, not triggering an actual fire event. That status change is reported to the Fire Alarm Control Panel as a supervisory signal. The panel uses supervisory signals to indicate that monitored equipment (like a fire pump) is operating or in a controlled state, so maintenance or supervising personnel know the pump is running and the water supply is being pressurized. An actual alarm would occur only if there were water flow from sprinklers or a valid detection event, and a trouble would indicate a fault or failure. So the system sends a supervisory indication to reflect the pump running.
