Mircom InnovairFlex D2 2 Wire Photoelectric Duct Smoke Detector

INNOVAIRFLEX 2-WIRE PHOTOELECTRIC DUCT DETECTOR

Description

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 duct work.
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 (-4ºF to 158ºF) 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 ¾ 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 detector.
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.
The InnovairFlex 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, 90A and CAN/ULC S524 for additional duct smoke detector application information.
