Bosch Security offers the DS291 Series Duct Smoke Detectors. The DS291 includes a DS291 Air Duct Smoke Detector Housing complete with a DS260 Ionization Smoke Detector for 4-wire loops and a 1.5 foot sampling tube. The DS291P Air Duct Smoke Detector has a DS250DH Photoelectric Smoke Detector for 4-wire loops in place of the DS260.
