An address type fire detection device that generates AC current with multiple frequency components AND a fire detection system including the same

摘要

An address-type fire detector for generating an alternating current having a plurality of frequency components includes an address setting unit generating an address code value corresponding to an electrical connection state of each of a plurality of switches, and a plurality of address code values corresponding to the address code values one-to-many. A microprocessor for adding and outputting a frequency signal and an operation confirmation voltage to the output value of the fire detection sensor, and outputting an AC voltage having a plurality of frequency components corresponding to one-to-many address code values, but adding an operation confirmation voltage to the output value of the fire detection sensor It characterized in that it comprises a voltage-frequency converter for outputting the added value to be reflected in the amplitude of the AC voltage, and a voltage-to-current converter for driving a current corresponding to the voltage level of the AC voltage to the power line.
