Data Sheet: DNRECL

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.
