Intelligent DNRE Duct Smoke Detector

The InnovairFlex™ DNRE intelligent non-relay photoelectric duct smoke detector features versatile mounting options in square or rectangular configuration with modular construction.

The DNRE Intelligent Duct smoke detector senses airflow speeds ranging from 0.5 -20meters per second with proven System Sensor precision. It improves false alarm immunity (with plug-in sensor head); detect smoke even in the harshest duct applications; broadens operating temperature (-20ºC to 70ºC) and humidity (0-95 percent non-condensing) ranges; simplifies installation, saving your time and money.

The improved cover design, with the integrated the low-flow feature, isolates the sensor head from the low-flow technology for simple maintenance.
