SL-DA4R Series
Analog Addressable Duct Smoke Detectors
(Hi-Temp, Low-FLow & No-Tools)
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 unit’s on-board alarm contact 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 SLDA4R. This philosophy provides a new level of efficiency in
after-purchase value to both the installer/servicer 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. The key features below detail many of the customer-driven innovations
incorporated in the SL-DA4R Series. Innovative product
combined with unsurpassed customer service equals the
right combination for all of your projects.
