  As shown in FIG. 4, when the battery detector 28 is attached to the fire detector 10 and power is turned on by supplying power to the detector controller 12, the detector controller 12 performs step S <b> 1 (hereinafter “step” is After the predetermined initial processing is performed in step (Omitted), an off control signal is output to the power switch unit 26 to be fixed in the off state in S2, and power supply from the battery power source 28 to the device circuit unit 14 is stopped.

  In S <b> 2, the sensor control unit 12 accesses the memory 38 of the wireless tag 30 via the wired interface by the I / F circuit units 24 and 40, writes power-off information, and confirms the power state by the operation device 100. Keep it in a possible state.

  Subsequently, the process proceeds to S3, where the sensor control unit 12 sets the sleep mode to be in a substantially non-operating state. In this state, the process proceeds to S4, where the wireless tag is connected via the wired interface by the I / F circuit units 24, 40. 30, the set address of the rewrite flag is periodically read, and when the rewrite flag is detected, the power-on information is written by the operating device 100 in the memory 38 of the wireless tag 30 in S5. The rewritten power-on information is read from a predetermined address in the memory 38 of the wireless tag 30.

  Note that when the power-off information is written in the memory 38 of the wireless tag 30 by the operation device 100 with the power switch unit 26 being turned off, the power-off information is read in S5, but fire detection Since the device 10 is already in the power-off state, the read power-off information is ignored and power-off control is not performed.

  In step S6, the power switch unit 26 is turned on. In step S7, the previous sleep mode is canceled to switch to the wake-up mode. In step S8, for example, the smoke concentration detection signal output from the sensor unit 20 has a predetermined fire threshold. When it exceeds, a predetermined sensor control is performed to generate and transmit a telegram signal indicating a fire.

  Even in the operation state in the wake-up mode, the sensor control unit 12 proceeds to S9 and accesses the memory 38 of the wireless tag 30 via the wired interface by the I / F circuit units 24 and 40 to periodically set the rewrite flag set address. When the rewrite flag is detected, the power-off information is written in the memory 38 of the wireless tag 30 by the operating device 100. Therefore, the power-off information rewritten from the predetermined address of the memory 38 is read out in S10, and S2 Then, the power switch unit 26 is turned on and the wake-up mode is canceled in S3 to switch to the sleep mode. In S4, detection of the next rewrite flag is awaited.

  When power-on information is written to the memory 38 of the wireless tag 30 by the operating device 100 with the power switch unit 26 turned on, the power-on information is read in S10. Since 10 is already in the power-on state, the read power-on information is ignored and power-off control is not performed.
