DNR-AUS

Analogue Addressable Duct Detector

dnr

The InnovairFlex DNR-AUS Intelligent Photoelectric Duct Smoke Detector features a pivoting housing that 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 metres 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.
