NFPA requires all fire dampers to be tested 1 year after installation and then every 4-6 years thereafter depending on the building type. Resetting fire dampers by hand after a test has been performed can be an unsafe, difficult, and time-consuming process. FiDO fire damper openers help make this process safer and easier, while also saving significant time and money. FiDO2 can open fire dampers up to 16"" in height.
