During detector testing, what should be verified on the control panel?

• A. It resets to factory settings automatically.
• B. It responds to test signals with appropriate alarms and logging results.
• C. It prints weather reports.
• D. It disables all alarms.

Answer: (B)

During detector testing, the key idea is to verify that the control panel responds to test signals with the right alarms and logs the results. When a detector is tested or simulated, the panel should trigger the appropriate audible and visual alarms and create a precise log entry that records what happened and when. This confirms that the detectors and the control panel are communicating correctly and that the system is documenting events for verification and compliance. Other options don’t fit: automatically resetting to factory settings would erase configurations, printing weather reports has no relevance to fire detection, and disabling all alarms would defeat the purpose of testing and compromise safety.
