The SK-DUCT-W and DNRW use photoelectric technology to detect smoke and combustion particles present in air moving through an HVAC air handling system.
These units sense smoke in the most challenging conditions, operating in airflow speeds of 100 to 4,000 feet per minute (0.5 ? 20.32 m/s), temperatures of -4?F ? 158?F (-20?C ?70?C), and a humidity range of 0 ? 93 percent (non-condensing).
