A design of a fire alarm system based on dual-signal detection and transmission

Disadvantages such as high false alarm rate and the duration of long checking cycle time appear in current fire alarm equipments/systems. In view of these disadvantages, this paper presents data communications using non-conventional and conventional data communications to achieve a combination of information transmitting fire alarm system working principle, the main system controller analysis, the area controller analysis, the detection of the first line and software design. Through set the main program flow of area controller, according to judge the rate of temperature rise, the system can effectively reduce the false alarm rate while reducing the pressure on the central controller.
