InnovairFlex combines an impressive collection of innovations
shaped by your field experience and our life safety design expertise.
One unit can accommodate multiple installation footprints to overcome
mounting constraints. Tool-free, snap-in sampling tubes speed and
simplify installation. Broad temperature and humidity ranges accommodate
exposure to environmental extremes. Easily visible status indications
and a readily accessible test feature simplify testing and maintenance.
With its unmatched flexibility, InnovairFlex can adjust to fit any
The InnovairFlex D2 2-wire photoelectric duct smoke
detector features a pivoting housing that fits various applications:
both square and rectangular footprints mount to round or rectangular
This new duct smoke detector senses airflow speeds
ranging from 100 to 4,000 feet per minute with proven System Sensor
precision. The enhancements built into this model improve false alarm
immunity (with plug-in sensor head); broaden operating temperature (?4°F
to 158°F) and humidity (0 to 95 percent noncondensing) ranges; while
simplifying installation and maintenance.
These advance features
can detect smoke even in the harshest duct applications. The new design
provides more wiring space with an added 3/4 inch conduit knockout.
Numbers and labels for terminal designations are consistent with
previous Innovair models. The new sampling tube can be clicked into
position with one smooth motion from either the front or the back of the
The InnovairFlex D2 duct smoke detector has signals to
indicate trouble and maintenance conditions. Additionally, a cover
tamper feature is incorporated to indicate a trouble condition for
removed or improperly installed sensor cover. An improved cover design,
with an integrated the low-flow feature, isolates the sensor head from
the low-flow technology for simple maintenance.
series is designed for greater flexibility and reliable smoke detection
to simplify installation and maintenance. The new InnovairFlex product
line is backward compatible to existing 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.
