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
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.
• 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
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 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 ³/4-inch
conduit knockout and ample space to facilitate easy wiring and
mounting of relay module.
• 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 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.
