The InnovairFlex™ 2-Wire Conventional Photoelectric Duct Smoke Detector features a pivoting housing which fits both square and rectangular footprints, capable of mounting to a round or rectangular duct. These units sense smoke in the most challenging conditions, operating in airflow speeds of 0.5 to 20 meters per second,
temperatures of -20 °C to 70 °C and a relative humidity range of 0 to 95 percent, non-condensing. An improved cover design isolates the sensor head from the Low-Flow feature for simple maintenance. A Cover Tamper feature provides a fault signal if the sensor cover is removed or improperly installed. The InnovairFlex™
housing has a 20 mm conduit knockout and ample space for wiring. The InnovairFlex™ Duct Smoke Detector can be customized to meet local requirements and specifications without additional wiring. The product line utilises a new sampling tube range, but remains compatible with all previous Innovair models, including remote test accessories.
