の中継器。[Claim for Utility Model Registration] A plurality of repeaters are connected to the signal line drawn out from the receiver, and at least three different signal voltages are generated depending on the detection state of the gas leak detector connected to each repeater. In a repeater of gas leak alarm equipment that transmits a signal to a receiver side, when a gas leak signal voltage output from a gas leak sensor is detected, the gas leak signal is transmitted to a first signal line from the receiver. a gas leak signal detection circuit that relays and outputs a voltage; and a signal voltage supplied from the receiver via a second signal line when a normal signal voltage of the gas leak sensor is detected to be relayed to the next stage as a normal signal voltage. A normality detection circuit is connected to the normality detection circuit of the receiver, and a termination element is provided in the final stage repeater to convert the normal signal voltage supplied from the previous stage repeater into a specified voltage. 1, and a switching circuit for intermittent normal signal voltage to the next-stage repeater when the normality detection circuit detects a failure of the gas leak detector. A repeater for gas leak alarm equipment.
