Until the audio signal lines KPn-KPCn are cut off, a noise sound may be generated from the speaker 4 or the short-circuit protection circuit 18 may operate due to an abnormal waveform signal generated by a drop in the power supply of the amplifier circuit 15. That is, the operation becomes unstable between the time when the power supply of the amplifier circuit 15 is turned off and the time when the output of the amplifier circuit 15 becomes completely zero, and the output of the speech synthesis circuit 14 is not completely zero during this time. Therefore, the signal of an abnormal waveform may be output from the amplifier circuit 15. Noise noise due to this signal may be output from the speaker 4 or the short-circuit protection circuit 18 may be operated. By the way, if the short-circuit protection circuit 18 operates, it will not be restored unless the power supply of the sound alarm device itself is turned off, so it is troublesome to restore once the short-circuit protection circuit 18 operates.

First, in step S10, it is determined whether or not the district sound stop state is generated by operating the district sound stop switch 8, for example, the state in which the district sound representative signal B is not input during the sound warning output. The process is repeated, and if the district sound is stopped, the process proceeds to step S12, and the corresponding individual relay K is turned off. That is, when the speakers 4 and 4 of the common area on the first and second floors of the apartment house are sounding, the relays K1 and K2 are turned off. Relays K1, K2 is the contact k 1, k 2 is turned off is opened, the 1st and the speaker 4, 4 of the second floor of the shared portion is disconnected from the amplifier circuit 15. At this point, no sound is output from the speakers 4 and 4. After the relay K is turned off, that is, after the contacts k 1 and k 2 are opened, a wait of 5 msec is performed in step S14, and after the elapse of 5 msec, the amplifier start signal to the amplifier power control circuit 16 is turned off in step S16 (ie, "L" level). As a result, the power supply to the amplifier circuit 15 is turned off and stopped. After turning off the amplifier start signal, the control signal for starting the voice synthesizing circuit 14 is turned off (that is, set to "L" level) in step S18. As a result, the voice synthesis circuit 14 stops. FIG. 2 is a time chart showing the above operation. In this figure, time T1 is waiting for a time of 5 msec.
