Duct Detector

Building, fire, and life safety codes often require the installation of duct smoke detection in heating, ventilating, and air conditioning (HVAC) ducts for the detection of fires in an HVAC System. Typically, these codes refer to NFPA 90A, Standard for the Installation of Air Conditioning and Ventilating Systems, to determine if and where they are required. Duct smoke detectors provide early detection of smoke and products of combustion present in air moving through HVAC ducts. These devices are designed for the prevention of smoke recirculation in areas by air handling systems. Fans, blowers, and complete systems may be shut down in the event of smoke detection.
