What should be included in periodic testing/maintenance records for detectors?

• A. Insurance policy numbers for alarms.
• B. Cartridge inventory.
• C. Employee names attached to each alarm.
• D. Documentation of detector testing, alarm function checks, and maintenance actions.

Answer: (D)

The main idea is that records for detector upkeep must prove the system is functioning and being actively maintained over time. The best record content is a clear log of what was tested, the results of those tests (for example, whether detectors triggered correctly and within expected timeframes), and any maintenance actions taken (such as calibrations, sensor replacements, battery changes, or repairs). This creates traceability and accountability, showing regulators and facility managers that the safety system is ready to warn in a real event and that issues are being addressed promptly.

Other items listed don’t fit because they don’t reflect the detector’s performance or its maintenance history. Insurance policy numbers for alarms aren’t about the detector’s function. Cartridge inventory concerns munitions assets, not the detector system. Employee names attached to alarms aren’t relevant to the detector’s status and could introduce unnecessary privacy considerations; they don’t contribute to confirming the system’s readiness. In short, documentation should focus on how the detectors were tested, how the alarms performed, and what maintenance actions were executed, with dates, who performed them, results, and planned next checks.
