Air sampling detectors are not prone to nuisance alarms.

• A. True
• B. False
• C. Not specified
• D. Not applicable

Answer: (A)

Air sampling detectors reduce nuisance alarms by actively pulling air from the protected space and monitoring it over time rather than reacting to a single brief spike. Because they sample from multiple points through a network and use time-averaged or rate-of-rise alarm logic, short-lived gusts, transient leaks, or background fluctuations are less likely to trigger an alarm. The system typically requires a sustained concentration above threshold (or a rising trend) before it alarms, which smooths out temporary disturbances. Proper maintenance—keeping sampling lines clean, filters in place, and sensors calibrated—keeps this advantage, while neglect can allow blockages or drift to reintroduce nuisance alarms.
