Duct Smoke Delivery Tools

The DSDS and DSDP are Duct Detector accessories that facilitate a clever method for testing duct smoke detectors from an accessible location per NFPA requirements which calls for test smoke to be properly introduced into the duct’s airstream. DSDS and DSDP are intended for indoor use only and use with return-side or supply-side (up to 95' and 4' respectively per UL) duct smoke detectors.

Applications include easier, more timely testing of hard to access duct detection devices within hospitals, schools, warehouses, commercial kitchen spaces, and even other devices such as fire smoke dampers.
