Which indicator is illuminated specifically during a danger condition?

• A. DANGER indicator
• B. WARNING indicator
• C. SAFE indicator
• D. Detector head indicator

Answer: (A)

During a danger condition, the DANGER indicator lights because it is the signal designed to grab attention and tell you there is an immediate, life-threatening situation that requires urgent action. A WARNING indicator is used for hazard awareness that isn’t immediate, prompting caution and monitoring rather than urgent action. A SAFE indicator means everything is normal, with no active hazard. The detector head indicator simply shows the status of a detector device, not the overall danger state. So the DANGER indicator is the one that illuminates specifically when danger is present.
