Duct smoke detector limitations
SuperDuct duct smoke detectors will not operate without
electrical power.
SuperDuct duct smoke detectors will not operate as designed
outside of the listed electrical and environmental
specifications.
SuperDuct duct smoke detectors will not sense smoke unless
the ventilation system is operating and the sensor’s cover is
properly installed.
SuperDuct duct smoke detectors may not operate as designed
unless installed in accordance with these instructions and all
applicable national and local codes as determined by the local
authority having jurisdiction.
Product description
Overview
The duct smoke detector is used to detect smoke under
extended temperature ranges, typically in self-contained
commercial rooftop HVAC systems. In self-contained
commercial HVAC units, the HVAC equipment is enclosed in
a single package to protect the internal components
(compressor, condensing unit, heating coils, etc.) from adverse
environmental conditions. Hinged or removable service panels
provide access to the equipment.
