The Fire•Lite InnovairFlex D355PL intelligent non-relay photo- electric 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, UV resistant 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 4,000 feet per minute, tem- peratures of -4 degrees F to 158 degrees F, and a humidity range of 0 to 95 percent (non-condensing.) An improved cover design isolates the sensor head, which allows for ease of maintenance. A cover tamper feature indi- cates a trouble signal for a removed or improperly installed sen- sor cover. The Fire•Lite  InnovairFlex housing provides a 3/4- inch conduit knockout and ample space to facilitate easy wiring and mounting of a relay module. The Fire•Lite InnovairFlex duct smoke detector can be custom- ized 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.
