DNRA
Addressable Duct Smoke Detector

The Notifier InnovairFlex® DNR(A) 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, 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 (0.5
to 20.32 m/s), temperatures of -4°F to 158°F (-20°C to 70°C),
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 indicates
a trouble signal for a removed or improperly installed
sensor cover. The Notifier InnovairFlex housing provides a 3/
4-inch conduit knockout and ample space to facilitate easy wiring
and mounting of a relay module.
The Notifier 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.
