A detection alarm device comprising a gas leak detector electrically connected to a sonic transmitter that simultaneously emits a plurality of sound waves having different frequencies when the gas leak detector detects a gas leak, and a gas supply. A sonic discriminator is electrically connected to a gas circuit breaker installed in the road, and when the sonic discriminator simultaneously receives each sound wave of each frequency emitted by the sonic transmitter, the gas circuit breaker is activated. A gas leak alarm interlocking shutoff system consisting of a shutoff device.
