This product has been replaced by the DNR-AUS.

The DNRHS high sensitivity duct smoke detector provides very early warning of fires to protect high-value assets and mission critical operations from fire and the spread of damaging smoke through air management systems. The detector’s intelligent laser sensor can detect miniscule amounts of smoke flowing through duct work at air velocities from 1.524 metres per second to 20.32 metres per second — ideal for environments with high-velocity, high-volume air changes.

This product has been replaced by the combination of a DNR-AUS, fitted with a 7351-IV detector.
