What are the warning condition indications?

• A. Only the amber WARNING indicator illuminates.
• B. The amber WARNING indicator illuminates; the dark green SAFE indicator extinguishes; the light green detector head illuminates for the corresponding detector head; the warning relay energizes an amber strobe light and a buzzer in the CHT pump room.
• C. All indicators turn green.
• D. A red strobe light in the CHT pump room flashes.

Answer: (B)

Warning conditions are shown by a coordinated set of indicator signals that both alert you to a problem and point to where it is. When a warning is active, the amber WARNING indicator comes on to signal that attention is needed, while the dark green SAFE indicator goes out to show that the normal safe condition is not present. The specific detector that has been triggered lights up in light green, so you can identify the exact location of the issue. At the same time, the warning relay drives an amber strobe light and a buzzer in the CHT pump room, providing a clear audible and visual alert at the scene. This combination ensures you know there’s a warning, where it’s coming from, and that action is required.
