PURPOSE: A fire alarm system using the wireless communication is provided to reduce the damage of fire by taking fast action against the fire by notifying people in real time by sending alarm through wireless communication by sensing the fire through a plurality of sensor. CONSTITUTION: The alarm system comprises a sensor(1), a control processor(2), a signal change modifying part(3), a frequency synthesizer/transfer part(4), a buffer amplifier(5), a switching switch(7), a BPF/LPF(8), an RF detector(9), a power control part(10), and an antenna(11). The sensor(1) senses different signals of temperature, thermal energy, smoke, opening and closing of the fire exit and transfers them into electric signal and sends the sensed electric signal to the control processor. The control processor further comprises one-chip micro processor and a code and operation program are stored inside the ROM memory of the processor.
