Fire Smoke Damper Duct Detector. The device detects the presence of smoke in. nfpa 90a requires that if duct smoke detectors are connected to the building’s fire alarm system and are used “to cause the operation of hvac systems, smoke dampers,. what is a fire or smoke damper, where are they installed, and how should they be installed? the dsdf is designed for use with ruskin ul classified smoke and fire/smoke dampers. a fire damper closes once the duct temperature reaches a high enough level to melt a fusible link. combination fire and smoke dampers are used in heating, ventilation, and air conditioning (hvac) to protect duct and air transfer opening penetrations through fire smoke rated. address false alarms right at the source with patented optica led technology that uses dual wavelengths, multiple angles and detection algorithms to differentiate. finally, duct detectors are often used to initiate the operation of smoke dampers within ducts.
