DSDS Duct Smoke Delivery System
#1
Here is a video of the DSDS (Duct Smoke Delivery System) showing a new way to test duct smoke detectors using canned aerosol / smoke in less than 30 seconds. Using 8 feet of plenum rated tube connected to our nozzle that is mounted on the side of the duct work. The nozzle penetrates the side of the duct and is pointed at the sampling tube. I have attached pictures of the wall/ceiling plate with cover.
Patent Pending.
