Abstract
A method of monitoring smoke, fire, and temperature conditions includes transmitting light through a first fiber optic cable, the fiber optic cable terminating at a node disposed to monitor a smoke or fire condition at one or more predetermined areas, transmitting light along a second fiber optic cable, the second fiber optic cable arranged to monitor a temperature condition at one or more predetermined areas, receiving scattered light from the first fiber optic cable and/or the second fiber optic cable at a control system, and analyzing the scattered light to determine at least one of the presence and magnitude of smoke, fire and/or a temperature condition along the fiber harness or at the node.
