The Edwards 6263-SG is an Air Velocity Test Kit for Signature Series duct detector housings. First, it is a service and commissioning tool — not a fire alarm device itself. Specifically, technicians use it to measure airflow through Edwards Signature Series duct probes.
What is in the Edwards 6263-SG kit
The 6263-SG ships as a complete diagnostic kit. In addition to the test fixture, it includes an air velocity meter and a psychrometer. As a result, the technician can verify both duct air velocity and relative humidity in a single visit.
Where the 6263-SG fits
This kit pairs with Edwards Signature Series duct housings such as the SIGA-DH. Therefore, the technician uses it during commissioning of SIGA-SD intelligent duct smoke detectors. Also, it supports periodic testing and recommissioning per the building maintenance plan.
Why airflow verification matters
A duct smoke detector relies on sampling tubes that pull HVAC air across the sensing element. Specifically, the Edwards SIGA-SD operates between 100 and 4,000 ft/min duct air velocity. Therefore, if the duct airflow falls below 100 ft/min, the detector cannot reliably sample smoke. As a result, verifying airflow with the 6263-SG is a standard part of HVAC duct detector commissioning.
