This non-relay photoelectric smoke detector's pivoting housing is capable of mounting to a round or rectangular duct. Smoke can be sensed in 0.5m-20m/sec airflow, between -20 to 70 degrees C.

The weatherproof version of the InnovairFlex Intelligent Photoelectric Duct Smoke Detector. For extreme environments like rooftops, the DNRW can be installed without a costly enclosure.

A 2-wire InnovairFlex duct smoke detector, isolates the sensor head from the LowFlow feature for simple maintenance. The housing has a 20mm conduit knockout and ample wiring space.

A 4-wire photoelectric duct smoke detector, with an easy-access Test/Reset. Its three DIP switches can be used to configure field selectable settings. Can be customised to local codes.

Sampling tubes, which may be cut to length as necessary, for use in DNR, DNRW, D2 and D4120 Photoelectric Duct Detectors.
