Within how many seconds shall a trouble signal be returned to normal?

• A. 60
• B. 120
• C. 200
• D. 300

Answer: (C)

Trouble signals indicate a fault or monitoring condition that isn’t an active fire event but still needs attention. When the underlying fault is resolved, the panel should reflect that the system is back to normal, and the return-to-normal timing is chosen to balance reliability with responsiveness. A 200-second window gives enough time for transient issues to settle and for a fault to be truly cleared, while avoiding keeping the system in a troubled state longer than necessary. Shorter intervals could clear the trouble too quickly in the presence of fleeting fluctuations, and much longer intervals would delay accurate status reporting. Therefore, returning to normal within 200 seconds is the appropriate practice.
