Duct Smoke Detector
The duct smoke detector features a pivoting housing that fits various applications: both square and rectangular footprints mount to round or rectangular duct work.

This senses airflow speeds ranging from 1.5 - 20 metres per second with proven precision. The enhancements built into this model improve false alarm immunity (with plug-in sensor head); broaden operating temperature (-20ºC to 70ºC) and humidity (0 to 95 percent noncondensing) ranges; while simplifying installation and maintenance.
