At what interval are service personnel required to clean smoke detectors?

• A. Every 6 months
• B. Every year
• C. There is no requirement for periodic cleaning
• D. Only when alarms occur

Answer: (C)

Cleaning smoke detectors on a fixed calendar interval isn’t required. Maintenance focuses on ensuring detectors operate correctly through regular inspections and testing, and cleaning is performed only when the unit shows dirt or reduced performance, or per the manufacturer’s guidelines. In other words, the standard supports cleaning as needed based on condition and environment, not as a mandatory calendar-based task. This helps avoid unnecessary maintenance while still keeping detectors reliable; if a dusty or dirty detector is noted during inspection or testing, cleaning is carried out to restore proper sensitivity.
