• Duct Detector - 40950





Duct Detector Intelligent Addressable Duct Detector

Product Number: 40950


The 40950 series of duct smoke detectors systems samples air movement in heating and ventilation ducts by means of an intelligent smoke detector, housing, and air sampling tube.

An intelligent or conventional optical smoke or heat detector can be mounted in the 40950 housing.

Air in the ducts is sampled by the sampling tube/venturi pipe, which extends from the detector housing into the duct. The length of the Aluminium sampling tube can be shortened according to the diameter of the duct. However, if the ventilation duct is wider than 0.6 m, the sampling tube should penetrate the whole duct.

A filter can be attached to the duct detector for operation in dust environments.

A flexible 40950-BR enables mounting of the 40950 housing on rectangular and circular ducts with diameters as small as 100 mm.
