ム。[Scope of Claim for Utility Model Registration] A self-holding fire detector that is installed in a warning area and outputs a fire signal when a fire is detected; a battery; and a power source that supplies power from the battery to the fire detector. a recovery power supply control unit that is installed in the middle of the line and restores the fire detector by power control; a fire reception unit that receives a fire signal from the fire detector via the signal line; and a fire reception unit that receives a fire signal from the fire detector. At the same time, power is supplied from the battery to the wireless transmitting/receiving unit to modulate and transmit the fire signal to the central unit, and after the transmission, the wireless transmitting/receiving unit is switched to the receiving side and when a response signal from the central unit is received, the restoration is performed. a terminal device comprising: a control unit that restores the fire detector using a power supply control unit; under normal conditions, the wireless transmitter/receiver unit is switched to the receiving side, and a fire alarm is issued when a fire signal from the terminal device is received; and switch the wireless transmitter/receiver to the transmitter side,
A wireless fire alarm system comprising: a central device including a control unit that transmits a response signal indicating that a fire alarm has been issued to a terminal device; and;
