During sensitivity testing, we may not use an unmeasured amount of smoke or aerosol to test the smoke detector(s).

During sensitivity testing, we may not use an unmeasured amount of smoke or aerosol to test the smoke detector(s).

• A. True
• B. False
• C. Not enough information
• D. Not applicable

Answer: (A)

In sensitivity testing, you expose detectors to a defined, measured amount of smoke or aerosol rather than an unmeasured spray. This is essential because a detector’s stated sensitivity is based on a specific stimulus level. Using an unmeasured amount makes test results unreliable and non-reproducible, and it can lead to false conclusions about whether the detector will alarm within its listed range. By using a calibrated test source and knowing the concentration or obscuration level, you can verify that the detector responds as expected, document the results, and maintain safety and compliance. In practice, you follow the manufacturer’s procedure or standards, use a test aerosol with a known quantity, and confirm the detector activates within the specified sensitivity range.
