Expand the versatility of the InnovairFlex™ line of duct smoke detectors with System Sensor notification and test accessories.

The System Sensor DH400OE-1 is a steel enclosure for mounting a standard indoor rated duct smoke detector outdoors.

2D51 duct smoke detectors are low-profile photoelectric detectors designed for special applications, specifically for use in no-flow or low-flow air-handling systems (0 to 4,000 FPM).

InnovairFlex™ 4-wire photoelectric duct smoke detectors offer 2 sensors to 1 powerboard capability in standard (D4120) and watertight (D4120W) versions.

InnovairFlex™ 2-wire photoelectric duct smoke detectors sense airflow at speeds ranging from 100 to 4,000 ft/min.

The InnovairFlex™ Series are the only duct smoke detectors flexible enough to fit configurations from square to rectangular and everything in between.
