Air Duct Smoke Detector

Air Duct Smoke Detector

The U5006 is designed to detect the presence of smoke for the primary purpose of controlling blowers and dampers in air conditioning and ventiliation systems. Our U5006 uses the technology of the U5005 mounted into a fiberglass NEMA 4 enclosure. The unit mounts directly to heating, ventilating and air conditioning ducts and uses a cros-sectional sampling tube arrangement that allows large volume air sampling. Includes auxiliary alarm relay contact, which can be normally open or closed.
