Fire alarm controller

The invention provides a fire alarm controller, comprising a main CPU unit, a loop card, an alarm expanding card, a direct-control monitoring card, a DC IO card, an extinguishment control disc and a drive card. The main CPU unit is respectively connected with the loop card, the alarm expanding card, the direct-control monitoring card and the DC IO card; the drive card is connected with the direct-control monitoring card; the extinguishment control disc is respectively connected with the direct-control monitoring card, the DC IO card and the drive card. The incompatibility of a point detector and an aspiration smoke-sensing detector is solved; the direct-line control communication with high reliability is realized and the fire alarm controller further has the advantages of good compatibility and higher reliability.
