Description
The Silent Knight SK-DUCT-W Duct Smoke Detector is an advanced, addressable photoelectric detector engineered for detecting smoke in air handling systems under even the most demanding conditions. Featuring integrated low-flow sensing technology, this intelligent device is capable of detecting combustion particles in airflow speeds ranging from 100 to 4,000 feet per minute (0.5 – 20.32 m/s) — making it ideal for commercial HVAC applications.
Its innovative housing supports square or rectangular mounting configurations, ensuring broad installation flexibility. With operating temperature capabilities from -4°F to 158°F (-20°C to 70°C) and up to 93% humidity, the SK-DUCT-W is built to perform in a wide range of environmental conditions. A clear cover enables easy visual inspection, while the tamper-resistant design ensures added security by signaling a trouble condition if the cover is removed or improperly installed.
The SK-DUCT-W also features remote testing capabilities, tool-free sampling tube installation from the front or back, and an accessible sensor head with code wheels for simplified address setup. The housing includes a 3/4-inch conduit knockout for increased wiring space and can optionally accommodate a Form-C relay module for expanded functionality.
