How do you deal with fire smoke dampers in rated shafts? Installing a duct detector within 5 ft. of each damper? Do you use a damper that has both a heat detector and smoke detector built into the FSD? If so are you testing it yearly for proper operation? Just throwing it out there to see what others are doing.
