Discussion about Large Space Fire Prevention

The early fire detection in large space structures was introduced and the settlement was provided. The importance of the building electrical in the large space fire prevention were pointed out. The working principle, characteristics and typical applications of optical cross section smoke detectors and a dual-band image-based sense of flame detector were introduced. The working principle, characteristics and application areas of optical fiber grating temperature fire detector were also introduced. It could provide references for fire prevention.
