Abstract
A device and method for facilitating convenient measurement of airflow in a duct detector. The device may include a detector assembly and an airflow sensor mounted within the detector assembly. The airflow sensor may be coupled to a remote control device, such as via control circuitry. A method for testing airflow in the duct detector may be performed by measuring airflow in the detector assembly, generating a signal that corresponds to the measured airflow in the detector assembly, and determining whether the generated signal exceeds a predetermined threshold signal level. If the generated signal does not exceed the threshold signal level, alarms may be activated and/or blowers in a ventilation system may be deactivated.
