InnovairFlex D4120 4-Wire Photoelectric Duct Smoke Detector

The InnovairFlex D4120 4-Wire Photoelectric Duct Smoke Detector features 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 100-4,000 feet per minute, temperatures of -4 to 158 degrees F., and a humidity range of 0-95%.

For applications that require supply and return detection, InnovairFlex has a 2-to-1 sensor to power board capability, which eliminates the need to run power to a second power board.
