During a warning condition, which devices in the CHT pump room are activated?

• A. Amber strobe light and buzzer
• B. Red strobe light and bell
• C. Amber strobe light and buzzer
• D. Green indicators only

Answer: (C)

Warning conditions are meant to alert personnel that something needs attention but isn’t an immediate danger. In the CHT pump room, the standard alert is an amber strobe light paired with a buzzer. The amber color signals caution, and the buzzer provides an audible notification so the warning is noticed even if visibility or ambient noise is challenging. Red strobe lights with a bell would indicate a higher-severity alarm or emergency, while green indicators denote normal operation and aren’t activated during a warning.
