The InnovairFlex D4120 4-wire photoelectric duct smoke detector features a pivoting housing that fits both square and rectangular footprints. Because the detector mounts to round or rectangular ductwork, it is indispensable for Building Automation Systems, BAS, and HVAC applications. This duct detector unit senses smoke in the most challenging conditions, operating in airflow speeds of 100 to 4,000 feet per minute, temperatures of -4 deg. F to 158 deg. F, and a humidity range of 0 to 95 percent (non-condensing). A plug-in duct 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.
