Which statement correctly defines drift compensation in detectors?

• A. Adjustment to detector sensitivity to environmental changes.
• B. Replacement of detectors.
• C. Calibration of the panel battery.
• D. Increasing alarm volume.

Answer: (A)

Drift compensation is the automatic adjustment of a detector’s sensitivity to slow, ongoing environmental changes so its baseline reading stays accurate. This keeps the detector from triggering false alarms as conditions like dust buildup, humidity, temperature, or aging electronics shift over time. That’s why describing an adjustment to detector sensitivity to environmental changes is the correct choice. Replacing detectors, calibrating the panel battery, or increasing alarm volume don’t address this slow, baseline shift, so they aren’t about drift compensation.
