Duct Detector

Duct Detector

Duct Detectors are mounted on the outside of ventilation ducts with two tubes connected inside the duct to the Duct Detector. Should smoke enter the ventilation duct the smoke is forced into the probe and then into the Duct Detector. Inside the Duct Detector is a smoke detector which senses the smoke and signals the FAP. The air that is forced into the duct detector is then sent back into the ventilation duct by the exhaust probe.
