PURPOSE: Provided is an automatic fire extinguisher with a voice output function embedded which bases on the control of a micom to inform users of gas valve state immediately so that it enable users to control a gas valve remotely in emergency. CONSTITUTION: The automatic fire extinguisher with the voice output function embedded comprises the parts of: a phone(1) which is connected to a public telephone network through a public line(2); a ring detection part(3) which detects a ring signal; a micom(5) which notifies users of the valve state and gas leakage in a gas equipment(12) as users input a key; a relay(4) which is switched into the ring detection part or a transformer(6) by a control signal in the micom; the transformer which sends users' key input information into an internal device when the relay turns on and provides an output voice signal for users; a first filter(7) which eliminates noise in a key input signal and supplies to a dial interpretation part(8); the dial interpretation part which interprets users' key input signal and converts to data for supplying to the micom; the voice output part which generates voice message to inform users of the valve state and gas leakage; a second filter(10) which eliminates a voice signal in the voice output part and supplies to users through the transformer; and a speaker(11) which sends the voice signal in the voice output part to users directly.
