Duct Detector Accessory Velocity Test Kit

The SD-VTK is an air velocity test kit for Kidde SuperDuct duct smoke detectors, giving installers and testing technicians the stoppers needed to verify sampling tube airflow during commissioning and periodic testing.

Built for the commercial installer

NFPA 90A and the detector's own listing require a documented airflow verification at commissioning and on a recurring test interval. The SD-VTK provides the stopper hardware called out in the SuperDuct test procedure so the crew isn't left improvising a way to check sampling tube velocity in the field.
