SL-2000 Series
Duct Smoke Detectors
Hi-Temp, Low-Flow and No-Tools
The SL-2000 Series Smoke Duct Detector is the latest
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 in the event of smoke
detection. The SL-2000 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/reset key switches or push buttons.
The SL-2000 includes many features that represent true
innovations from current generation duct smoke detectors.
Our traditional installer/service-friendly approach has been
closely followed and expanded throughout the SL-2000.
This philosophy provides a.the installer/service and enduser. Our attention to detail has yielded a host of “No-Tools
Required” features, as well as a multi-application performance level as yet unmatched in the industry. Innovative
product combined with unsurpassed customer service
equals the right combination for all of your projects. The
key features below detail many of the customer-driven
innovations incorporated in the SL-2000 Series.
