Duct Smoke Detectors

When System Sensor introduced the Innovair line of duct smoke detectors, it was revolutionary.  Over the past few years System Sensor has taken feedback from users across the country to come up with an even better product:  InnovairFlex, a true collaboration of field experience plus expertise in life safety design and manufacturing.

The star of the InnovairFlex lineup is the D4120, a 4-wire photoelectric duct smoke detector that 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 to 4,000 feet per minute, temperatures from -4 to 158 degrees F, and a humidity range of 0 to 95 percent.   What make it even better is that it is easy to install, easy to test and easy to maintain. It also replaces most duct mounted smoke detectors on the market making it a logical replacement.
