InnovairFlex™ D4120 4-Wire Duct Smoke Detector

InnovairFlex™ D4120 4-wire duct smoke detectors sense smoke in the most challenging conditions, operating in airflow speeds of 100 to 4,000 ft/min, temperatures of –4 °F to 158 °F, and a humidity range of 0 to 95% non-condensing.

InnovairFlex™ D4120 4-wire photoelectric duct smoke detectors feature a pivoting housing that fits both square and rectangular footprints and mounts to round or rectangular ductwork. This unit senses smoke in the most challenging conditions, operating in airflow speeds of 100 to 4,000 ft/min, temperatures of –4 °F to 158 °F, and a humidity range of 0 to 95% non-condensing. A plug-in sensor head offers improved false alarm immunity and simple installation, testing, and maintenance. An improved cover design isolates the sensor head from the low-flow feature for simple maintenance.
