1,3-2,3-3. 4 is a power supply, 5 is a power supply backup battery unit, and 6 is a power supply automatic switching unit 3 for switching power supply from the power supply backup battery unit 5.
A power cut-off notification signal generating unit 7 received via the switching switch 3-3 of the first embodiment is provided with a battery use restriction which receives power supply from the power supply backup battery unit 5 via the switching switch 3-3 of the automatic switching unit 3 when the power is cut off. The signal detecting section 8 is a backup battery supply disconnecting section which disconnects the power supply from the power supply backup battery section 5 in response to the disconnection signal 11 from the battery use restriction signal detecting section 7. The power-off notification signal generating unit 6 is connected to the input side of the monitoring device 2 via the disconnection switch 3-1. The monitoring device 2 is connected to the input side of the battery use restriction signal detecting unit 7 via the disconnection switch 3-2. The battery use restriction signal detecting unit 7 is a backup battery supply disconnecting unit (disconnecting unit).
8 is connected to the input side. Further, the power-off notification signal generating section 6 and the battery use restriction signal detecting section 7 are connected to the power supply backup battery section 5 via the disconnection switch 3-3 and the backup battery supply disconnection section 8.

換部３の切換スイツチ３−1,3−２がａ側に倒れている
ので、監視装置２との通信はない。First, when the power supply is normal, all the contacts of the switching switches 3-1, 3-2, 3-3 of the automatic switching unit 3 when the power supply is turned off fall to the a side. For this reason, no backup battery is used, and all circuits are supplied with power from the power supply 4. And
The power-off notification signal generator 6 and the battery use restriction signal detector 7 are supplied with power from the power supply 4, but the switching switches 3-1 and 3-2 of the automatic switching unit 3 when the power is turned off fall to the side a. Therefore, there is no communication with the monitoring device 2.

Side, and the contact of the backup battery supply disconnection unit 8 is tilted to the side a until the disconnection signal 11 is input from the battery use restriction signal detection unit 7, so that the power supply backup battery unit 5
All circuits are supplied with power. Then, the power-off notification signal generating unit 6
Generates a notification signal 12 and notifies the monitoring device 2.

する。Upon receiving this notification signal 12, the monitoring device 2 sends a backup battery disconnection signal 13 to the device 1. This back-up battery disconnection signal 13 is transmitted to the battery use restriction signal detecting section 7.
Is detected, the disconnection signal 11 is output to the backup battery supply disconnecting section 8, and the backup battery supply disconnecting section 8 receives the disconnection signal 11 and moves the contact to the b side. Thus, the power supply to the circuit of the power supply backup battery unit 5 is cut off.

寿命を長くし保守点検を軽減できる効果がある。As described above, according to the present invention, when the power is turned off, a signal for notifying the power-off is sent to the monitoring means, and then the backup battery disconnection signal is sent from the monitoring means to the switch means for connecting the backup battery and the power-off notification signal generating means. Is sent to disconnect the connection between the backup battery and the power-off notification signal generating means. As a result, since the power supply from the backup battery is cut off, the power supply from the backup battery is not continuously performed when the power supply is cut off, so that the life of the backup battery can be prolonged and the maintenance and inspection can be reduced.
