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 (non-
condensing). 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.
