in the event of fire, provide a conduit for fire, hot smoke and cold smoke. An intumescent fire damper, fitted into the duct at the point where it penetrates a fire resistant construction, will prevent the passage of fire and hot smoke. Lorient intumescent fire dampers fitted in conjunction with a Lorient automatic smoke control system will also provide protection against cold smoke. They have been shown by specific testing to be equivalent to a conventional damper, not only in fire and smoke barrier properties but also by exhibiting insulation values.
