With the characteristic of visual fire-alarm signal in an ordinary fire-alarm video surveillant system to add no may more sensors within the equipment.

Optical fiber methods may offer alternatives to well-established conventional devices and a fluorescence-based fire alarm system has been developed specially to address this requirement.

In order to standardize the order of dispatch command when receiving fire alarm and to secure fire fighting forces being dispatched accurately and in time, the definition of fire rank is defined according to the experience in fire categories, fire scales and fire times when the state rule has not been enacted.

A fire-alarm prediction system based on multi-sensor information fusion is presented,the block diagram of the system hard-ware is introduced,the soft-decision information fusion rule and its application in fire-alarm prediction is explained.
