System Sensor DNR(A): Intelligent Photoelectric Duct Smoke Detector

The System Sensor DNR(A) is an advanced, intelligent photoelectric duct smoke detector designed for optimal performance in a wide range of environments. Perfect for commercial, industrial, and residential applications, this smoke detector offers reliable protection with superior features that enhance both safety and ease of installation.

Key Features:

  • Photoelectric Sensing Technology: Equipped with integrated low-flow photoelectric technology, the DNR(A) provides highly accurate smoke detection, ideal for environments with varying airflow speeds.

  • Wide Airflow Velocity Range: The DNR(A) operates efficiently in airflow speeds ranging from 100 ft/min to 4,000 ft/min (0.5 m/s to 20.32 m/s), ensuring reliable smoke detection even in high-velocity environments.

  • Versatile Mounting Options: The DNR(A) is designed with a pivoting housing that fits both square and rectangular duct footprints. It can be mounted on round or rectangular ducts, making installation simple and flexible.

  • Broad Environmental Tolerance: This detector is built to perform in extreme 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.

  • Tamper-Resistant Design: Featuring a cover tamper signal, the DNR(A) provides an alert if the sensor cover is removed or improperly installed, ensuring ongoing reliability and safety.

  • Easy Maintenance and Accessibility: The detector includes an improved cover design that isolates the sensor head for easy maintenance. It also offers a 3/4-inch conduit knockout for simplified wiring and a larger space for mounting relay modules.

  • Remote Testing: The DNR(A) supports remote testing capabilities for convenient system checks without needing to disassemble the unit.

  • UL and FM Approved: The DNR(A) is UL and FM listed, ensuring it meets high safety and reliability standards. It is also compatible with all previous models and remote test accessories.
