Agency Listings
The InnovairFlex D4120W watertight 4-wire photoelectric duct
smoke detector is UL listed as a watertight enclosure providing
protection against falling dirt, rain, windblown dust, splashing
and hose directed water. D4120W duct smoke detector features
a pivoting housing that fits various applications: both square and
rectangular footprints mount to round or rectangular ductwork.
This unit senses smoke in the most challenging conditions, operating
in airflow speeds of 100 to 4,000 feet per minute, temperatures
of –4°F to 158°F, and a humidity range of 0 to 95 percent (noncondensing). A plug-in sensor head offers superior false alarm
immunity. These features, plus a NEMA 4 rating, allow operators to
mount the detector to rooftop HVAC equipment or use the detector
in other harsh environments.
The new design provides the same form, fit, and wiring terminations
as the standard InnovairFlex unit. Superior test and operational
features added to the standard model are also available in this
watertight unit. As the only watertight duct smoke detector on the
market, D4120W provides unsurpassed environmental protection
while simplifying installation, testing, and maintenance.
This 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 are NOT a substitute for open
area smoke detectors; NOT a substitute for early warning detection;
NOT a replacement for a building’s regular fire detection system.
Refer to NFPA 72 and 90A for additional information.
NOTE: To maintain the watertight properties of this duct smoke detector, watertight
conduit and fittings must be used. Mount the product with the conduit holes facing
downwards, if possible

*Please refer to the corresponding installation manual for accessory wiring diagrams.
Important Interconnect Notes
• When using the interconnect feature, all interconnected units must be powered using the same independent supply.
• Polarity must be maintained throughout the interconnect wiring. Connect the INT+ terminal on unit 1 to the INT+ terminal on unit 2 and so on. Similarly,
connect the INT/AUX– terminal on unit 1 to the INT/AUX- terminal on unit 2 and so on.
• Up to 50 D4120W units may be interconnected.
• Up to 10 DH100ACDC units may be interconnected. Please note that each of the 9 DH100ACDC units interconnected may be replaced by three D4120W
units. Therefore, when using the interconnect feature a single DH100ACDC can drive either 9 DH100ACDCs or 27 D4120W units.
* NOTE: Alarm can be reset only at the initiating device and not at the devices interconnected.
