NFPA 72 requires sensitivity testing of smoke detectors every two years. Other than building a mock up and removing duct smoke detectors for testing on the mock up how can non intelligent duct smoke detectors be tested for sensitivity
Seems like it would depend on the brand and model of the device.
Call the manufacture and ask??
To many brands out there, and various year models.
There are equipments available in the market used for testing smoke detector sensitivity. It's expensive but most Maintenance companies doing Fire Alarm has it. That's the option I can only suggest.
