Notifier DNRE Duct Detector Housing

Notifier Model DNRE Air Duct Smoke Detector utilizes photoelectric technology forthe detection of smoke. This detection method, when combined with an efficient housing design, samples air passing through the duct and allows detection of a developing hazardous condition. When sufficient smoke is sensed,an alarm signal is initiated at the fire control panel monitoring the detector,and appropriate action can be taken to shut off fans, blowers, change over airhandling systems, etc. These actions can facilitate the management of toxicsmoke and fire gases throughout the areas served by the duct system
