Intelligent Non-Relay Photoelectric Duct Smoke Detector The InnovairFlex™ Series are the only duct smoke detectors flexible enough to fit configurations from square to rectangular and everything in between. Features •Photoelectric, integrated low-flow technology •Air velocity rating from 100 ft/min to 4000ft/min (0.5m/s to 20.32m/sec) •Versatile mounting options: square or rectangular configuration •Broad ranges for operating temperature (-4F to 158F) and humidity (0% to 95% non-condensing) •Patented sampling tube installs from front or back of the detector with no tools required •New Cover tamper signal •Increased wiring space with a newly added 3/4-inch conduit knockout •Available space within housing to accommodate mounting of relay module •Easily accessible code wheels on sensor head (sold separately) •Clear cover for convenient visual inspection •UL 268A listed •Remote testing capability •Requires com line power only •NEMA Type 4 UL listed for non-hazardous indoor and outdoor applications (DNRW only) •UV Resistant, UL listed housing and cover material (DNRW only) The InnovairFlex DNR intelligent non-relay photoelectric duct smoke detector and DNRW watertight non-relay photoelectric duct smoke detector feature a pivoting housing that fits both square and rectangular footprints capable of mounting to a round or rectangular duct. DNRW duct smoke detector, with its NEMA 4 rating, is listed as a watertight enclosure providing protection against falling dirt, rain, and windblown dust, splashing and hose directed water, allowing operators to use the detector in the most extreme environments. These units sense smoke in the most challenging conditions, operating in airflow speeds of 100 to 4000 feet per minute, temperatures of -4F to 158F, and a humidity range of 0 to 95 percent (non-condensing). An improved cover design isolates the sensor head from the lowflow feature for simple maintenance. A cover tamper feature was added to indicate a trouble signal for a removed or improperly installed sensor cover. The InnovairFlex housing provides a 3/4-inch conduit knockout and ample space to facilitate easy wiring and mounting of relay module. The InnovairFlex duct smoke detector can be customized to meet local codes and specifications without additional wiring. The new InnovairFlex product line is compatible with all previous Innovair models, including remote test accessories. WARNING: Duct smoke detectors have specific limitations. Agency Listings 2911 DUCT SMOKE DETECTORS ARE: NOT a substitute for an open area smoke detector, NOT a substitute for early warning detection, and NOT a replacement for a building’s regular fire detection system. Refer to NFPA 72 and 90A for additional duct smoke detector application information.
