A distributed temperature system with at least one optical fiber is provided. Each optical fiber runs horizontally and vertically within at least one compartment of a ship. Each optical fiber connects to a distributed temperature system unit or is multiplexed to a single temperature system unit. The system employs Optical Time Domain Reflectometry to support measurements of optical pulses in processing bins defined along the fiber. The spatial fidelity of the measurement capability is sufficient to localize a fire detection in individual shipboard compartments. The system can diagnosis conflagration events that produce fire and also flooding in the compartment.

Fire detection and conflagration event monitoring and diagnosis system

A pair of vector sensors are provided and mounted orthogonally to each other. Each vector sensor includes a central structural member having a first end and a second end. The central structural member has four symmetric arms oriented at 90&#xb0; to each other. A crystalline plate is attached perpendicular to a distal end of each arm of the central structural member. The first end of each vector sensor is embedded in a socket of a proof mass. The second end of each vector sensor is embedded in an aperture of a cubic base.
