' NV 4F NRW Intelligent Photoelectric Duct Smoke Detectors The DNR and DNRW use photoelectric technology to detect smoke and combustion particles present in air moving through an HVAC air handling system. i 1 The Gamewell-FCI DNR intelligent non-relay photoelectric duct smoke detector and DNRW watertight non-relay photoelectric duct smoke detector feature a pivoting housing that fits : both squarea nd recta ngularfootprints capable of mounting to around or rectangular duct. The DNRW duct smoke detector,with its NEMA-4 rating,is listed as a watertight,UV resistant enclosure providing protection againstfa Ili ng 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(0.5—20.32 m/s),temperatures of-4°F—158°F(-20°C— 70°C),and a humidity range of 0—95 percent(non-condensing.) An improved cover design isolates the sensor head,which allows for ease of maintenance.A r, cover tamper feature indicates a trouble signalfor a removed or improperly installed sensor cover.The housing provides a 3/4-inch conduit knockout and ample space to facilitate easy wiring and mounting of a relay module. The Gamewell-FCI DNR duct smoke detectors can be customized to meet local codes and =: specifications without add itionalwiring and are compatible with all previous models, including remote test accessories. ACCESSORIES Gamewell-FCI provides system flexibilitywith a variety of accessories,including two remote test stations and different means of visible and audible system annunciation.As with our duct smoke detectors,all duct smoke detectors accessories are UL listed.
