The Duct Smoke Delivery System (DSDS) is a breakthrough solution for smoke detector testing and maintenance in commercial HVAC systems. Designed to simplify testing and ensure full compliance with fire codes, DSDS makes it easier and safer to perform critical inspections without taking shortcuts.

DSDS delivers test smoke directly and precisely to duct-mounted detectors using a patented delivery method. This eliminates the guesswork and inefficiencies of traditional return-side testing, and makes testing accessible, fast, and foolproof.

Why DSDS?

• Ensures safer, faster, and fully code-compliant smoke detector testing

• Reduces labor time and eliminates the need for risky or improvised testing methods

• Minimizes disruption to building operations

• Prolongs detector lifespan through correct and consistent testing
