Description
The SL-DA4R Series Smoke Duct
Detector is the latest analog
addressable innovation for early
detection of smoke and products of
combustion present in air moving
through HVAC ducts in Commercial,
Industrial, and Residential applications.
The unit is designed to prevent the recirculation or spread of smoke by air
handling systems, fans, and blowers.
Complete systems may be shut down
via the building’s fire alarm control
panel (FACP) in the event of smoke
detection.
The SL-DA4R is designed and built to
meet all local code requirements, as
well as the NFPA and ICC standards
regarding HVAC supply and return duct
smoke detectors. Output terminals are
provided for a wide range of remote
accessories such as horns, strobes,
remote status indicators and test key
switches or push buttons.
The SL-DA4R includes many features
that represent true innovations from
current generation duct smoke
detectors. Our traditional installer /
servicer-friendly approach has been
closely followed and expanded
throughout the SL-DA4R. This philosophy
provides a new level of efficiency in
after-purchase value to
both the installer/servicer and enduser.
