Abstract This paper is devoted to the system for fire detection and extinction which uses power line as bus. And the spread spectrum technology is introduced to the system for fire detection and extinction. According to the low power density and high interference suppression characteristic of the spread spectrum communication system, it can decrease the high error code rate of the system which only uses FSK or ASK modulation method. The characteristic of error code probability in this system is analyzed.

Key words： System for fire detection and extinction Spread spectrum communication system Pseudorandom （PN） sequence Code division multiple access
