The Honeywell Farenhyt DNR / DNRW Intelligent Duct Smoke Detector is an intelligent solution designed to detect smoke within Heating, Ventilation, and Air Conditioning (HVAC) duct systems. It helps identify smoke in air moving through ventilation ducts and sends a signal to the fire alarm system, enabling the appropriate response. The series utilizes intelligent photoelectric detection technology and integrates with Farenhyt addressable fire alarm systems to provide accurate and reliable monitoring. The DNR is designed for standard applications, while the DNRW is intended for more demanding environmental conditions, making the series suitable for a wide range of commercial, industrial, and building fire protection applications.
The Honeywell Farenhyt DNR / DNRW Intelligent Duct Smoke Detector is designed to provide reliable and intelligent smoke detection within Heating, Ventilation, and Air Conditioning (HVAC) duct systems. By continuously monitoring air moving through ventilation ducts, the detector helps identify the presence of smoke and communicates alarm conditions to the connected Farenhyt fire alarm control system, supporting an effective response to potential fire conditions.
The DNR / DNRW series utilizes intelligent photoelectric smoke detection technology to detect smoke particles carried through HVAC ductwork. Its addressable design allows the detector to communicate directly with the fire alarm control panel, enabling centralized supervision and accurate identification of detector status. This intelligent communication enhances system monitoring while supporting efficient inspection, testing, and maintenance.
The DNR model is designed for standard duct smoke detection applications and provides a practical solution for commercial, institutional, and industrial facilities. The DNRW version is designed for applications requiring additional environmental protection, making it suitable for more demanding installation conditions where enhanced resistance to environmental exposure is required.
These detectors are designed to work as part of an integrated fire alarm system and can help initiate programmed system responses when smoke is detected within the ductwork. Depending on the fire alarm system configuration, these responses may include generating an alarm or supervisory signal and supporting the programmed control of associated HVAC equipment to help limit the movement of smoke through the building.
The detector housing is designed to support installation on HVAC ductwork while allowing air samples from inside the duct to be evaluated by the smoke detector. This configuration provides effective monitoring of air distribution systems and helps detect smoke that could otherwise be transported between different areas of a building through ventilation ducts.
With intelligent addressable operation, photoelectric smoke detection, centralized system monitoring, and options for standard or more demanding environments, the Honeywell Farenhyt DNR / DNRW Intelligent Duct Smoke Detector provides a dependable solution for HVAC smoke detection in a wide range of commercial, industrial, and institutional fire protection applications.
