Extent: E+W+S+N.I.

Smoke damper means, for the purpose of implementing Regulation II-2/B/9a, a device installed in a ventilation duct which under normal conditions remains open allowing flow in the duct and is closed during a fire, preventing the flow in the duct to restrict the passage of smoke and hot gases. A smoke damper is not expected to contribute to the integrity of a fire rated division penetrated by a ventilation duct. In using the above definition the following terms may be associated:
.1 automatic smoke damper means a smoke damper that closes independently in response to exposure to smoke or hot gases;
.2 manual smoke damper means a smoke damper intended to be opened or closed by the crew by hand at the damper itself; and
.3 remotely operated smoke damper means a smoke damper that is closed by the crew through a control located at a distance away from the controlled damper.
