The Farenhyt DNR Intelligent Photoelectric Duct Smoke Detector is a highly reliable device designed for early detection of smoke in HVAC ducts. It features advanced low-flow technology, enabling it to operate effectively in airflow speeds ranging from 100 to 4,000 feet per minute (0.5 to 20.32 m/s). This makes it suitable for a wide range of environments with varying airflow conditions.

The detector is built with a pivoting housing, allowing it to fit both square and rectangular footprints, and it can be mounted on round or rectangular ducts. Its robust design ensures reliable performance in challenging conditions, with an operating temperature range of -4°F to 158°F (-20°C to 70°C) and a humidity tolerance of 0% to 95% (non-condensing).

Additional features include a patented sampling tube for easy installation, a clear cover for visual inspection, and a cover tamper signal to indicate if the sensor cover is removed or improperly installed. The detector also provides ample wiring space and includes a 3/4-inch conduit knockout for convenient installation. It is compatible with remote testing accessories and can accommodate an addressable relay module for applications requiring a Form-C relay.

This detector is ideal for commercial and industrial settings, offering reliable smoke detection in HVAC systems to enhance safety and compliance.
