All alarm pilot lights should be in what state?

All alarm pilot lights should be in what state?

• A. On
• B. Off
• C. Steady
• D. Blinking

Answer: (B)

Alarm pilot lights are status indicators for faults or alarms in the fire pump control system. In normal operation, there are no active alarms, so these indicators must be dark. If a problem occurs, the lights illuminate to signal an alarm or fault, typically either steadily or blinking depending on the panel’s design. This illumination alerts maintenance or operators that attention is needed. Therefore, the correct state for all alarm pilot lights during normal conditions is off. If any light is on during testing or normal operation, it indicates an abnormal condition that should be investigated.
