The System Sensor DNRE Duct Detector Housing with B501AP Base is part of the advanced InnovairFlex range, designed to deliver reliable duct smoke detection in commercial and industrial HVAC systems (Sensor Head Sold Separately)
Featuring intelligent photoelectric detection and integrated low flow technology, the DNRE housing ensures dependable performance across a wide range of environmental conditions.
The pivoting housing design allows flexible installation on both square and rectangular duct configurations, making it suitable for a variety of applications. With support for airflow speeds from 1.5 m/s to 20.3 m/s, the DNRE is engineered to perform effectively even in challenging airflow environments.
Designed with ease of installation and maintenance in mind, the improved cover isolates the sensor head from low flow features, while a tamper resistant cover provides a trouble signal if the cover is removed or incorrectly installed. Additional wiring space and a 20 mm conduit knockout further simplify installation.
Ideal for commercial buildings, offices, healthcare facilities, schools, and industrial environments, the System Sensor DNRE provides dependable duct smoke detection with flexible mounting and simplified maintenance.
