Which of the following tests are required for system type smoking detectors in one- and two- family dwellings?

• A. Functional test per manufacturer's instructions
• B. Sensitivity test using a calibrated sensitivity test instrument
• C. Smoke entry test using smoke aerosol
• D. All of the above

Answer: (A)

Testing system-type smoke detectors in one- and two-family dwellings centers on ensuring the device actually operates and signals correctly. The required method is a functional test conducted according to the detector manufacturer’s instructions. This verifies that the detector senses smoke, triggers the alarm, and properly communicates with any linked devices or control panels as designed, using the procedure specified by the maker. Sensitivity testing with a calibrated instrument is typically associated with commercial or higher-risk systems and isn’t a standard requirement for residential, system-type detectors. Smoke entry testing, which checks whether smoke can reach the sensor from a test aerosol path, is also not a general requirement for these dwellings. So, the only mandated approach in this scenario is performing the functional test per the manufacturer’s instructions.
