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 (detector head sold separately) •Air velocity rating from 300 ft/min to 4000ft/min (1.52m/s to 20.32m/sec) •Versatile mounting options: square or rectangular configuration •Broad ranges for operating temperature (−4°F to 158°F) 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 ¾-inch conduit knockout •Available space within housing to accommodate mounting of relay module •Clear cover for convenient visual inspection •UL 268A listed •Remote testing capability •Requires com line power only The InnovairFlex DNRECL intelligent non-relay photoelectric duct smoke detector features a pivoting housing that fits both square and rectangular footprints capable of mounting to a round or rectangular duct. The intelligent non-relay photoelectric duct smoke detector senses smoke in the most challenging conditions, operating in airflow speeds of 300 to 4000 feet per minute, temperatures of −4°F to 158°F, and a humidity range of 0 to 95 percent (non-condensing). An improved cover design isolates the ED-DP or ED-DPI sensor head from the low-flow 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 ¾-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. 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.
