In a transmission device for an alarm device that converts physical quantities such as smoke, gas, temperature, etc. into electrical signals and sends back data signals, the power source of each terminal device includes a capacitor that is charged to a predetermined voltage by a transmission signal from the central device. A transmission device for an alarm device, wherein the central device outputs a power supply signal different from the transmission signal between the call signals. (2) The transmission device for an alarm device according to claim 1, wherein the signal for the power source is a continuous signal or a pulse signal. (3) The transmission device for an alarm device according to claim 1, wherein the voltage of the power supply signal is higher than the voltage of the transmission signal.
