<p>The present invention provides a P-type and address-type automatic fire detection system in which different resistance values (hereinafter referred to as "specific resistance") are applied to each detector in a common P-type automatic fire detection system (hereinafter referred to as a "P-type system"), in which a specific resistance is provided to each of the detectors and then an address is identified by tracking the resistance value of a relevant detector when a fire is detected. The P-type and address-type automatic fire detection system in which a specific resistance value is applied to each of the detectors, according to the present invention, comprises: a down transformer (A1), which is installed so as to be connected to a common wire (A), for supplying an appropriate voltage to the relevant detector; a D/A convertor (DA) for converting a digital signal of the voltage supplied from the down transformer (A1) into an analog signal for measuring and supplying same; specific resistance detectors (10) for delivering a resistance value of the relevant detector to the wire by installing the detectors on the wire to which the analog signal converted by the D/A converter (DA) is supplied so that each of the detectors has a different value that is the specific resistance (RE), and then connecting the detectors with contact switches; a microcomputer (MC), which is installed so as to be connected to the wire (A) to which the D/A converter transmits, for registering a transmitted analog value from the wire as an initial value when no resistance value is present, registering an address to each of the specific resistance detectors (10) that have a unique resistance value, and outputting the address of the specific resistance detector (10) that is operated by calculating an analog value that is currently flowing from the initial analog value that is registered, when the resistance value of the relevant specific resistance detector (10) is delivered to the wire by means of operation by the detector; and a display (DP) for outputting to a screen and controlling data of the microcomputer (MC).
